Mystery of knowledge and our (Muslims) current state of affairs!

How it works?

We all know, last prophet of Allah, Muhammad Peace be Upon Him is the person bestowed with the Last Book from Allah that confirms final deeds required to be successful. Quran documents all those deeds.

Unfortunately this concept is not that simple now a days. This complexity is due to misunderstanding of something called " Knowledge ".

Our current definition of knowledge is, merely,  what we read in a book/scripture etc, and are supposed to practice. All our preachers, people in Masjid every (Friday) Jumma prayer and so called religious people wandering around in society have same understanding. This understanding is confirmed by not what we speak but what we practice.

If you are reading this, please revisit the definition of knowledge.
What we read in a book is nothing but an information.
If we are inspired enough by what is written in book, we try to practice this.
Once one start practicing this, he/she find him/her self confronting new experiences, an experience which is limited to his/her own understanding and is very difficult to explain that experience in words. This experience affects all the things in a realm, one live in. Now this new experience is called knowledge.

Give me a moment to explain this by some example. I read in a book, i should start every work by seeking blessing of Allah by reciting "Bismilla". This is just an information and has nothing to do with me till i start practicing this. Once i start practicing this, i find new things in my daily living which are quite new to me and have a visible impact on how i live this life. This impact, as per my understanding, is knowledge.

How i discovered this:
When I started listening and doing things in life, I was put to a Masjid to learn how to read Quran.
In Masjid, being a Brailvi Masjid, I was introduced with different "Silslas" like Chishtiya, Qaadriya etc. Later in my after 30's, I discovered that teachings of all saints, founder of these "Silslas" were different. In fact it was impossible to follow ways of all the sects, while everyone seems right in their deeds. Question, that pinched myself for long, how is it possible that all these teachings have so different directions yet are considered right?

Later this mystery was solved by three words, Maloom (information), Amal (Practice) and Ilam (Knowledge). It is when one mixes "Maloom" with "Amal", it results in "Ilam" and Ilam is what is required for a practicing Muslim.

If i am unable to achieve Ilam with my Maloom and Amal, it is like things are being wasted. Of course, there are different stages of knowledge and everyone has its own piece of experience.

Importance of Ilam:
The person, who holds Ilam, is called Alim in Islam and islamic literature is all full explaining blessings for an Alim. And who doesn't know about prayer of Nabi PBUH, Rabbi Ziddni Ilman.

Results:
Please revisit your definition of Ilam and do not consider that Mulvi sb says about it. Reject all so called Alims who just read things from Quran and command you and have nothing to do with practice and gaining experience out of what is written.

Note:
This is a personal opinion and documented based on experience of a single person. You may have your own version.

May Allah bless us all!

Working with VxVM mirroring

How to make RAID 1 in simple steps. 

In Lab i have:


1- RHEL 6 system
2- two 2GB disks
   i - disk_4 -> i'll refer this disk as p_disk
  ii - disk_5 -> i'll refer this disk as s_disk

Note: disk_4 and disk_5 are names reported by OS in vxdisk -e list

"Making Mirror"
1- Create a disk group "mdg" with disk_4 as p_disk
vxdg init mdg p_disk=disk_4

check vxprint output for new DG

vxprint -g mdg 
Output is as follow:
TY NAME         ASSOC        KSTATE   LENGTH   PLOFFS   STATE    TUTIL0  PUTIL0
dg mdg          mdg          -        -        -        -        -       -

dm p_disk       disk_4       -        4099840  -        -        -       -


2- Now add second disk in "mdg" as s_disk
vxdg -g mdg adddisk s_disk=disk_5

Verify disk addition in vxprint output:
[root@lab1 ~]# vxprint -g mdg
TY NAME         ASSOC        KSTATE   LENGTH   PLOFFS   STATE    TUTIL0  PUTIL0
dg mdg          mdg          -        -        -        -        -       -

dm p_disk       disk_4       -        4099840  -        -        -       -
dm s_disk       disk_5       -        4099840  -        -        -       -


3- Create a volume in DG "mdg" on disk s_disk named "mvol"
vxassist -g mdg make mvol 4099840 s_disk

Verify volume creation from vxprint output
[root@lab1 ~]# vxprint -g mdg
TY NAME         ASSOC        KSTATE   LENGTH   PLOFFS   STATE    TUTIL0  PUTIL0
dg mdg          mdg          -        -        -        -        -       -

dm p_disk       disk_4       -        4099840  -        -        -       -
dm s_disk       disk_5       -        4099840  -        -        -       -

v  mvol         fsgen        ENABLED  4099840  -        ACTIVE   -       -
pl mvol-01      mvol         ENABLED  4099840  -        ACTIVE   -       -
sd s_disk-01    mvol-01      ENABLED  4099840  0        -        -       -


4- Add mirror to "mvol" on disk p_disk
vxassist -g mdg -b mirror mvol p_disk

Verify status using vxprint as follow:
[root@lab1 ~]# vxprint -g mdg
TY NAME         ASSOC        KSTATE   LENGTH   PLOFFS   STATE    TUTIL0  PUTIL0
dg mdg          mdg          -        -        -        -        -       -

dm p_disk       disk_4       -        4099840  -        -        -       -
dm s_disk       disk_5       -        4099840  -        -        -       -

v  mvol         fsgen        ENABLED  4099840  -        ACTIVE   ATT1    -
pl mvol-01      mvol         ENABLED  4099840  -        ACTIVE   -       -
sd s_disk-01    mvol-01      ENABLED  4099840  0        -        -       -
pl mvol-02      mvol         ENABLED  4099840  -        TEMPRMSD ATT     -
sd p_disk-01    mvol-02      ENABLED  4099840  0        -        -       -



NOTE: "TEMPRMSD" status of mvol-02 states that mirror is in process of sync.

verify sync process from vxtask list
[root@lab1 ~]# vxtask list
TASKID  PTID TYPE/STATE    PCT   PROGRESS
   191     -     ATCOPY/R 23.33% 0/4099840/956416 PLXATT mvol mvol-02 mdg auto-throttled


vxprint output after sync is complete:
[root@lab1 ~]# vxprint -g mdg
TY NAME         ASSOC        KSTATE   LENGTH   PLOFFS   STATE    TUTIL0  PUTIL0
dg mdg          mdg          -        -        -        -        -       -

dm p_disk       disk_4       -        4099840  -        -        -       -
dm s_disk       disk_5       -        4099840  -        -        -       -

v  mvol         fsgen        ENABLED  4099840  -        ACTIVE   -       -
pl mvol-01      mvol         ENABLED  4099840  -        ACTIVE   -       -
sd s_disk-01    mvol-01      ENABLED  4099840  0        -        -       -
pl mvol-02      mvol         ENABLED  4099840  -        ACTIVE   -       -
sd p_disk-01    mvol-02      ENABLED  4099840  0        -        -       -



Removing Mirror

Decide which disk is to remain active - Let's say i want p_disk to remain in DG and remove s_disk (remember we created volume originally on s_disk and then add p_disk for mirror - so logically p_disk is a secondary copy which will be primary after removal of s_disk from DG)

1- Remove mirror copy on disk s_disk
vxassist -g mdg remove mirror mvol '!s_disk'

NOTE: '!s_disk'  --  single quotes have been used since any command starting with ! on linux sometimes refers to some shell keyword and consequently failing of the command.

Verify results from vxprint:
[root@lab1 ~]# vxprint -g mdg
TY NAME         ASSOC        KSTATE   LENGTH   PLOFFS   STATE    TUTIL0  PUTIL0
dg mdg          mdg          -        -        -        -        -       -

dm p_disk       disk_4       -        4099840  -        -        -       -
dm s_disk       disk_5       -        4099840  -        -        -       -

v  mvol         fsgen        ENABLED  4099840  -        ACTIVE   -       -
pl mvol-02      mvol         ENABLED  4099840  -        ACTIVE   -       -
sd p_disk-01    mvol-02      ENABLED  4099840  0        -        -       -


Note: "mvol" is left with just one copy on plex mvol-02 while mvol-01 is removed. although mirror is removed but disk s_disk is still part of DG "mdg".

2- Let's remove s_disk from DG as well.
vxdg -g mdg rmdisk s_disk

Verify results from vxprint:

[root@lab1 ~]# vxprint -g mdg
TY NAME         ASSOC        KSTATE   LENGTH   PLOFFS   STATE    TUTIL0  PUTIL0
dg mdg          mdg          -        -        -        -        -       -

dm p_disk       disk_4       -        4099840  -        -        -       -

v  mvol         fsgen        ENABLED  4099840  -        ACTIVE   -       -
pl mvol-02      mvol         ENABLED  4099840  -        ACTIVE   -       -
sd p_disk-01    mvol-02      ENABLED  4099840  0        -        -       -



Good Luck with VERITAS mirroring.

Where did i go wrong!

Being in IT support business and especially data center support, life is always a rush. While on the way back to home, escaping from the same rush, and feeling bit hot, I just randomly started thinking about the cold days those we used to have round the old house "Angeethi" or furnace in December and January. What a life and peace experience that was.

In fact, now a days we experience cold only for two weeks or so if I compare it with the one in childhood. Suddenly my eyes got blinded with the light emerging from head lights of a fancy car driven by some young chap - lo and behold - suddenly my thoughts emerged like of a taste on tongue of a person experiencing extreme acidity and stomach disorder. In struggle to keep myself at peace, I just started reasoning, why this young chap needed these gloomy head lights for his car? The only reason came to my mind was upcoming fog days, perhaps. By the way, one can find people on road in summer hot days with more bright light than coming out of this car’s head lights.

Believe me it was a revelation telling me if I’ll use these head light for my car, those can make some other driver or passer by blind, I’ll NOT be blessed with fog and peace of childhood. It was the moment of realization, being able to afford 50k budget for my house electricity needs only, doesn't make me eligible to have it. In big canvas I am something odd and this odd outlook is what is forbidden for me (May be in Islam too).

May Allah Bless us all with wisdom to know the reality of these worldly materials and to use them for better.

What if i was given the chance to make “prime” decisions about Pakistan – Please not funny!


Don’t judge me – its just a list of things, as i think, can fix Pakistani problems and highlight our features as a nations. Here goes the list

>    Own the religion – by saying this i mean take ownership of every masjid and madrasa from “private” owners and make them “public”.
>    Hurting someone on basis of faith difference – make it a most harsh of crimes and punish it accordingly
>    Define criteria for a person to be speaker in mosque. Punish badly if happens contrary.
>    >Define a strict criteria on basis of education and research, both, specially research for a person to be a preacher (well this is most important of all).
>    Ban all gatherings on the basis of religions – annual gatherings (tableeghi jamat, dawat-e-Islamic, dawah etc). Gathering can be allowed after proper permission and a reason to gather like some procession etc.
>    Ban recitation of all the books like “fazail-e-amal”, “faizan-e-sunnat” etc. in gatherings and push the nation to read more from Quran.
>    Make financial figures of religious institutions public and accountable.
>    Make criteria for being “Molana”, “Hazrat” etc. right now it looks like we say in punjabi “anni riyooriyaaN wandh di paee ay” mean a blind woman is distributing sweets.


Well I'll add more to the list. Mind it – it is an opinion and wish and don’t be offended.

comments are welcome.

Arranged Vs Love marriage



Arranged Vs Love marriage


I have been discussing this topic in my own teenage / adulthood and used to be very confused. Although there is not much to be confused about it but you know the teenage!. Most prominent feelings of those days used to be “what to do if I fall in love with someone?” Please don’t be judgmental as, it never happened for myself. As life is being squeezed with every mark of year and is evolved too – at last found the answer of few questions. So sharing those answers is agenda of this little writing and may this be a guide to the young ones (although it might not be the case).
I’ll not hook myself with this ongoing debate of
Ø  Being in love and then marriage OR
Ø  Being in love and be married with someone who is chosen by parents OR
Ø  Being in frame of reference where emotions do not matter and one binds himself or herself with the choice of parents OR anything that one can think of.  
One will have to give space and margin to the second party in order to make the relation a success; any relation from friendship to wife/husband. If we consider this a rule of thumb then look at the marriage choices above. The choice that gives maximum chance to this rule – can be a way forward.
Please don’t choose partner on the basis of material. “She is so hot” “damn he is so beautiful and rich” “she got the figures man” could all these typos be a reason/basis of a relation like marriage?
People please consider marriage a sacred relation and do not ruin it because of “fatal illness” called “jawani”. Why I’ll use “illness” for the part of life which is full of joy and energy? It’s because of surroundings and things those affects/directs our decisions and emotions.

Thinking rational and requesting pardon


This Friday on Jumma prayer, it happened – I concentrated the "dua" which Imam sb was requesting to Allah. It was all about our sins that we may have done due to which we are flooded every year. I really didn't find any objection within myself over this philosophy but I thought – our sins might not be the only reason for these earthly disasters. On a closer look, EU and US have these problems too. For instance, I thought of the Japan and its last disaster.
I think, it's our negligence and lack of interest to fix the issue that is playing. On a stronger note, it's our struggle to not to change and to resist every factor that tends to change ourselves. Even this attitude encompasses Godly hints that encourage us to look upon ourselves and make us understand the need to adapt.
Birth of every single child is a clear sign that Allah has accounted for the recent technology changes and social evolution, we are passing through. Children were not so "fast and furious" even a decade back. I am 36 and I see people above 50 years are quite afraid of these latest technology and gadgets, even if they want to learn it.

 

May Allah bless us with right words while praying!
