Hi all,
we have one Lustre 2.5.3 with ZFS 0.6.3, and another one with Lustre 2.10.3 and ZFS 0.7.6
I have copied a number of directories from old to new, and noticed that the number of inodes given by
'lfs quota' differ.
Extreme example is a user with just one file:
# lfs quota -h -u USER /lustre/old
Disk quotas for usr USER:
Filesystem used quota limit grace files quota limit grace
/lustre/old 133k 0k 0k - 1 0 0 -
# lfs quota -h -u USER /lustre/new
Disk quotas for usr USER:
Filesystem used quota limit grace files quota limit grace
/lustre/new 60k 0k 0k - 2 0 0 -
(Size difference is easy: it is a text file, and only the OSS in the 'new' FS have compression enabled.)
I suppose some counting scheme has changed between those Lustre versions?
However, some copied directories have much larger count-differences, but some have identical numbers.
Cheers,
Thomas
