Working on my ZFS Build, using a SuperMicro 846E1 chassis and an LSI 1068e SAS
controller, I'm wondering how well FM works in OpenSolaris 2009.06.
I'm hoping that if ZFS detects an error with a drive, that it'll light up the
fault light on the corresponding hot-swap drive in my enclosure and any
st way of doing this without
setting up a complex HA service and at the same time minimising load on the
master?
Thanks in advance and sorry for the barrage of questions,
Matt.

solution.
I even tried simply copying /etc/zfs/zpool.cache to
/a/etc/zfs/zpool.cache and not exporting/importing the data pool at all,
however this gave the same hostid problem.
thanks for your help.
cheers

Dan,
Tried export data after beadm umount, but on reboot zpool data is simply
not imported at all...
So exporting data before reboot dosen;t appear to help..
thanks

Hi list,
I've got a pool thats got a single raidz1 vdev. I've just some more
disks in and I want to replace that raidz1 with a three-way mirror. I
was thinking I'd just make a new pool and copy everything across, but

Thanks Eric, however seeing as I can't have two pools named 'tank', I'll

Hi Matt,
You have several options in terms of migrating the data but I think the
best approach is to do something like I have described below.

I want to monitor the read and write ops/bandwidth for a couple of pools

I've got a system with 3 WD and 3 seagate drives. Today I got an email
that zpool status indicated one of the seagate drives as REMOVED.
I've tried clearing the error but the pool becomes faulted again. Taken

t; method mentioned above
worked swimmingly for me. I was nervous doing this during production hours, but
the release command returned in about 5-7 seconds with no apparent adverse
effects. I was then able to destroy the snap.
I was initially afraid that it was somehow the "memory bug" mentioned in the
current thread (when things are fresh in your mind, they seem more likely), so
