Hi Rick,
Last November I had 'negative' file count reported quota for two groups.
Checking it now the count for one of them got 'positive.' I guess user just
wrote more files.
The file count reported by robinhood was 1,634 and 3924 files.

[root@lfsb ~]# lfs quota -qh -g thermog /mnt/lfsa
/mnt/lfsa 0k 0k 0k - 18446744073709550831 0
0 -
[root@lfsb ~]# lfs quota -qh -g c51 /mnt/lfsa
/mnt/lfsa 0k 0k 0k - 18446744073709551611 0
0 -
interestingly:
>>> hex(18446744073709551611)
'0xfffbL'
>>> hex(18446744073709550831)
'0xfcefL'
Right now lfs quota reports same large number of files for group c51:
18446744073709551611
and [almost] no space used.
# lfs quota -g c51 /mnt/lfsa
Disk quotas for group c51 (gid 9886):
Filesystem kbytes quota limit grace files quota limit grace
/mnt/lfsa 0 1048576 1048576 - 18446744073709551611* 1024
1024 -
I can mount mdt snapshot and take a look but I have to know what to look for.
This is lustre 2.5.3 GA with few patches. zfs-0.6.4.1
Alex.

Alex,
Were you ever able to get more details about this problem? Thanks.
