reinitializing quota on xfs

reinitializing quota on xfs

[Jan Engelhardt]

Hi,


for some strange reason, `quota -v` showed an impossible number in the 
inodes (files) field, something that resembled 2^64 - n, n={1..100}. I do 
not know how it happened, but I wanted to reinitialize the quota. Though, 
how does one do that with XFS? (Since it's different from the vfsv0 quota 
architecture.)

By chance, I could make xfs reinit it using:
  quotaoff /D
  touch /D/something
  umount /D
  mount /D   # impliclty mounts with usrquota,grpquota (options in fstab)

but it would have been nicer to have a mount option.

It would be really good if we could get a test case for this; it
gets reported once in a blue moon, so there does seem to be some
latent issue there...

See xfs_quota(8) from recent versions of xfsprogs, or in older
ones theres doco in /usr/share/doc/xfsprogs*/README.quota.

cheers.

I'll try figure out a testcase.

I can't find it in xfsprogs-2.7.11/man/man8/xfs_admin.8 ... or it's too 
well hidden.
