Hi Guys,
maybe someone has some time to take a look at my issue, I didn't find a answer
using the search.
Here we go:
I was running a backup of a directory located on a ZFS pool named TimeMachine,
before I started the job, I checked the size of the directory called NFS, and
du -h or du -s was telling me 25GB for /TimeMachine/NFS. So I started the job
after a while I was very surprised that the backup app requested a new tape,
and the a new one again, so in total 3 tapes (lto1) for 25GB ??!?!
After that I checked the directory again:
r...@fileserver:/TimeMachine/NFS# du -h .
25G
r...@fileserver:/TimeMachine/NFS# du -s
25861519
r...@fileserver:/TimeMachine/NFS# ls -lh
total 25G
-rw-r--r-- 1 root root 232G 2009-09-25 14:04 nfs.tar
zfs list TimeMachine/NFS
NAME USED AVAIL REFER MOUNTPOINT
TimeMachine/NFS 24.7G 818G 24.7G /TimeMachine/NFS
Also, if I use nautilus under Gnome, he also tells me that Directory NFS used
232GB and not 24.7GB as du and zfs list reports to me ?!?! Same if I mount
that share (AFP) from a Mac and via NFS, still got 232GB used for
TimeMachine/NFS.
r...@fileserver:/Data/nfs_org# ls -lh
total 232G
-rw-r--r-- 1 root root 232G 2009-09-24 17:57 nfs.tar
r...@fileserver:/Data/nfs_org# du -h .
232G .
r...@fileserver:/Data/nfs_org#
I've upgraded from snv_118 to snv_123 but still the same. I also copy the
contend of the directory to another ZFS spool, removed the org content and copy
it back again, but I still get an incorrect value!
