[Gluster-users] Quota going crazy

[Jonathan MICHALON]

Thanks, good catch. I didn't find anything in quota*.log but didn't have a look in the bricks subdir…

Looks like the problem is about null gfid. Now I have no idea how it can happen to have a null gfid… :)

Searching for nulls I found a one in some xattrs:
trusted.glusterfs.quota.00000000-0000-0000-0000-000000000001.contri=0x00000a1bafc7f200
This looks rather strange too, maybe it's related?

P.S. sorry for bad formatting, but have to use OWA…

Hi Jonathan,

Are there any error related to quota in the brick log?

Thanks,
Vijay
