Description Saurabh 2011-04-18 07:07:12 UTC 
over the fuse mount also the amount of data displayed is similar to the one by back-end

[root@centos-qa-client-1 d1]# cd ../d2

dd: closing output file `f.3': Disk quota exceeded

[root@centos-qa-client-3 sbin]# getfattr -m . -d -e hex /mnt/drep/d2/f.2
getfattr: Removing leading '/' from absolute path names
# file: mnt/drep/d2/f.2
trusted.afr.drep-client-2=0x000000000000000000000000
trusted.afr.drep-client-3=0x000000000000000000000000
trusted.gfid=0x422837d4c6174f6880c050cd8650be21
trusted.glusterfs.quota.032245e2-9380-4deb-8dfa-ed1aebeb7ca4.contri=0x000000000007f000

after calculation 7f00=520192, where as the back-end shows 512000



[root@centos-qa-client-3 sbin]# ls -li /mnt/drep/d2/f.1
4620397 -rw-r--r-- 1 root root 512000 Apr 18 02:53 /mnt/drep/d2/f.1





hence the quota limits gets filled up soon.


Finding this bug only in this glusterfs 3.2.0qa14 release.
Comment 2 Anand Avati 2011-04-18 11:56:29 UTC 
This is due to the new way of using st_blocks to account for quota usage. Expected behaviour.
