[LU-805] lfs quota should show quota allocation rather than used

Wed, 9 May 2012 12:24:26 +0000

lfs quota give actual used rather than what has been allocated. But what is allocated what really effects the user. Here is an example

sh-3.2# lfs quota -u treddy /nobackupp30
Disk quotas for user treddy (uid 10787):
Filesystem kbytes quota limit grace files quota limit grace
/nobackupp30 208932428 210000000 420000000 - 14641 75000 100000 -

This shows that he is under his soft quota. But if we look at what he is allocated

pbspl1 ~ # lfs quota ~~v -u treddy /nobackupp30 | awk '$2 == "~~"

{ sumu = sumu + $1; suma = suma + $3 }

END

{ print sumu, suma, "\n" }

'
> 208932428 220463104

We see that his allocation (220,463,104) is over the softlimit (210,000,000). Therefore his grace time has been accumulating and in fact it is expired.

I have a modified version of lfs tool that does a better job of providing the quota info.

bash-3.2# /usr/local/bin/lfs.nas quota -v -u treddy /nobackupp30
Disk quotas for user treddy (uid 10787):
Filesystem kbytes quota limit grace files quota limit grace
/nobackupp30 208932428* 210000000 420000000 None 14641 75000 100000 -
nbp30-MDT0000_UUID
6844 - 131072 - 14641 - 20480 -
nbp30-OST0000_UUID
2352640 - 2490368 - - - - -
nbp30-OST0001_UUID
1963180 - 2097152 - - - - -
...

nbp30-OST0076_UUID
2860332 - 3014656 - - - - -
nbp30-OST0077_UUID
1344680 - 1441792 - - - - -
------- -------
Total 208932428 220463104

We see here that he has no grace time left and the softlimit has turn into a hardlimit. In order to reset his grace time he must delete enough data to drop his allocation below his softlimit. In this case it would be ~10,217 MB.

So it would be better to show total allocated in the lfs quota output. Example in this case should be

Disk quotas for user treddy (uid 10787):
Filesystem kbytes quota limit grace files quota limit grace
/nobackupp30 220463104* 210000000 420000000 None - 14641 75000 100000 -
