Hello... Since there has been much discussion about zpool import failures
resulting in loss of an entire pool, I thought I would illustrate a scenario
I just went through to recover a faulted pool that wouldn't import under
Solaris 10 U5. While this is a simple scenario, and the data
Greetings,
I have Sun Fire 4600 running Solaris 10, running Sun Cluster 3.2.
SunOS hubdb004 5.10 Generic_120012-14 i86pc i386 i86pc
We ran into some space issues in /usr today, so as a quick fix, I created a
slice (c5t0d0s12) with about 25GB of disk in order to create some zfs
filesystems
Richard,
Having read your blog regarding the copies feature, do you have an
opinion on whether mirroring or copies are better for a SAN situation?
It strikes me that since we're discussing SAN and not local physical
disk, that for a system needing 100GB of usable storage (size chosen

to an even number of disks.
I still have yet to purchase the system due to my issues with finding
the right board with the right SATA controller. My desktop system at
home runs an nVidia 590a chipset on a Foxconn motherboard and Solaris
U3 will only recognize the DVD drive during installation
I considered this as well, but that's the beauty of marrying ZFS with
a hotplug SATA backplane :)
I chose the to use the 5-in-3 hot-swap chassis in order to give me a
way to upgrade capacity in place, though the 4-in-3 would be as easy,
though with higher risk.
1. hot-plug a new 500GB SATA disk
You don't have to do it all at once... ZFS will function fine with 1
large disk and 1 small disk in a mirror, it just means you will only
have the as much space as the smaller disk.
As of things now, if you have multiple vdevs in a pool and they are of
diverse capacities, the striping becomes
Greetings.
I applied the Recommended Patch Cluster including 120012-14 to a U3
system today. I upgraded my zpool and it seems like we have some very
strange information coming from zpool list and zfs list...

Try exporting the pool then import it. I have seen this after moving disks
between systems, and on a couple of occasions just rebooting.

Is it possible to force ZFS to nicely re-organize data inside a zpool
after a new root level vdev has been introduced?
e.g. Take a pool with 1 vdev consisting of a 2 disk mirror. Populate some
arbitrary files using about 50% of the capacity. Then add another 2
mirrored disks to the pool.

Hi Jim,
The handout referenced is in fact the second of the two PDF documents
