continue using rsync between a ZFS pool and an LVM2 pool. At the very
least, have two ZFS pools.
For ZFS over iSCSI, have some zpool-layer redundancy because
I was looking into something like that last year, I was mirroring two iSCSI
drives using ZFS. The only real problem I found was that ZFS hangs the pool
for 3 minutes if an iSCSI device gets disconnected, unfortunately ZFS waits
for the iSCSI timeout before it realises something has happened.
Great to hear the driver works, I'll cross my fingers that my cards eventually
turn up.
I'm pretty sure I read something about work being done on ZFS to smooth out
those lumpy writes, I'm not 100% sure it's the same problem but it did sound
very similar. I can't remember the RFE / bug number
Exporting them as one huge iSCSI volume is good if you're paranoid about data
loss. You can use raid5 or 6 on the Linux servers, and then mirror those
large volumes with ZFS. The downside is that it's much harder to add
storage. I don't know if iSCSI volumes can be expanded, so you might

Hi there!
I made a dumb but serious error:
I have a 500G external usb disk with a zfs-pool containing only this one disk.
I then installed a new OS on my host-computer (debian with zfs-fuse) and wanted
to access my usb-drive again. I know now that ZFS saves the pool-data on the

If we get two x4500s, and look at AVS, would it be possible to:
1) Setup AVS to replicate zfs, and zvol (ufs) from 01 - 02 ?

For Solaris 10, one will need to purchase AVS. It was not until
OpenSolaris, that AVS became bundled. Also the OpenSolaris

This is not true. If on the primary
