That's not a limitation, just looks like one. The cluster's resource
type called "SUNW.nfs" decides if a file system is shared or not. And it
does this with the usual "share" and "unshare" commands in a separate
dfstab file. The ZFS sharenfs flag is set

replicate single boxes with local drives. And, in case OpenSolaris is
not an option for you due to your company policies or support contracts,
building a real cluster also A LOT cheaper.

Jim, it's okay. I know that you're a project leader at Sun Microsystems
and that AVS is your main concern. But if there's one thing I cannot
withstand, it's getting stroppy replies from someone who should know
better and should
en.
In any case and any disk size scenario, that's something you don't want
to have on your network if there's a chance to avoid this.

If you already have an X4500, I think the best option for you is a cron
job with incremental 'zfs send'. Or rsync.

g has been that the drive was unavailable
right after the *creation* of the zpool. And replacing a broken drive
with itself doesn't make sense. And after replacing the drive with a
working one, ZFS should recognize this automatically.

the average I/O
transaction size. There's a good chance that your I/O performance will
be best if you set your recordsize to a smaller value. For instance, if
your average file size is 12 KB, try using 8K or even 4K recordsize,
stay away from 16K or higher.

May I ask how you accomplish that?
And why are you doing this? You should replicate your zpool to another
host, instead of mirroring locally
ld sleep better if I were responsible for an application
under such a service level agreement without full high availability. If
a system reboot can be a single point of failure, what about the network
infrastructure? Hardware errors? Or power outages?
I'm definitely NOT some kind of know-i
the error count which iostat
reports without a reboot, so this method is not suitable for monitoring
purposes.
