Hi,
I am looking for the file system ownership information of ZFS file system. I
would like to know the amount of space used and number of files owned by
each user in ZFS file system. I could get the user space using 'ZFS
userspace' command. However i didn't find any switch to get Number of files
I have three zpools on a server and want to add a mirrored pair of ssd's for
the ZIL. Can the same pair of SSDs be used for the ZIL of all three zpools or
is it one ZIL SLOG device per zpool?

Actually, this brings up a related issue. Does anyone have experience
with running VirtualBox on iSCSI volumes vs NFS shares, both of which
would be backed by a ZFS server?

It is entirely true. You absolutely cannot use ESX with a guest on a block
device without formatting the LUN with VMFS. You are *FORCED* to use VMFS.
You can format the LUN with VMFS, then put VM files inside the VMF

Hi Paul,
I am using EXSi 4.0 with a NFS-on-ZFS datastore running on OSOL b134. It

I'll try to summarize my experience here, albeit our system does not provide

Hi Giovanni,
The spare behavior and the autoreplace property behavior are separate
but they should work pretty well in recent builds.
You should not need to perform a zpool replace operation if the
autoreplace property is set. If autoreplace is set and a replacement

Let say I have zfs filesystem export/test1, which is shared over NFSv3

Thank you all for your help. It appears my understanding of parity was rather
limited. I kept on thinking about parity in memory where the extra bit would be
used to ensure that the total of all 9 bits is always even.
In case of zfs, the above type of checking is actually moved into checksum.

Hello,
In OpenSolaris b111 with autoreplace=on and a pool without spares,
ZFS is not kicking the resilver after a faulty disk is replaced and
shows up with the same device name, even after waiting several
minutes. The solution is to do a manual `zpool replace` which returns
the following:

I've regularly heard people mention data corruption in network layer here - and
