I'm using Open Solaris 10 doing some test on ZFS and Zpool.I've encountered a
situation that caused the system crash.
There are two SCSI disks connected to my computer, c1t0d0 was used as the
bootable disk, c1t1d0 was used to test ZFS and Zpool.

Gino,
Were you able to recover by setting zfs_recover?
Unfortunately no :(
Using zfs_recover not allowed us to recover any of the 5 corrupted zpool we had
..
Please note that we lost this pool after a panic caused by trying to import a
corrupted zpool!
tnx,

Gino,
Can you send me the corefile from the zpool command?
This is the only case where we are unable to import a corrupted zpool but not
having a kernel panic:

Hi All
I'd like to expose two points about ZFS that I think are a must before even
trying to use it in production:
1) ZFS must stop to force kernel panics!
As you know ZFS takes to a kernel panic when a corrupted zpool is found or if
it's unable to reach
a device and so on...
We need to have

There was some discussion on the always panic for fatal pool failures issue
in April 2006, but I haven't seen if an actual RFE was generated.

Hi,
I have a zpool with only one disk. No mirror.
I have some data in the file system.
Is it possible to make my zpool redundant by adding a new disk in the pool
and making it a mirror with the initial disk?
If yes, how?
Thanks
Martin

Read the man page for zpool. Specifically, zpool attach.

Hi Martin,
Yes, you can do this with the zpool attach command.
See the output below.
An example in the ZFS Admin Guide is here:

Hello Basrt,
tanks for your answer. The filesystems on different projects are sized between
20 to 400 gb. Those filesystem sizes where no problem on earlier installation
(vxfs) and should not be a problem now. I can reproduce this error with the 20
gb filesystem.

You'd want to export them, not detach
Is there a more elegant approach that tells rmvolmgr to leave certain
devices alone on a per disk basis?
I was expecting there to be something in rmmount.conf to allow a specific device
or pattern to be excluded but there appears to be nothing. Maybe this is an RFE?

As you know ZFS takes to a kernel panic when a corrupted zpool is found or
one quickdirty way of backing up a pool that is a mirror of two
devices is to zpool attach a third one, wait for the resilvering to
finish, then zpool detach it again.
The third device then can be used as a poor man's simple backup.
How would you access the data on that device?

This sounds a lot like:

Which would allow us to retry write failures on
alternate vdevs.
Of course, if there's only one vdev, the write should be retried to a different
block on the original vdev ...

Are you sure you have a pool with that name not a filesystem in a pool
with that name ?
See zfs(1)

You'd want to export them, not detach them.
But you can't export just one branch of the mirror, can you?
Off the top of my head (i.e. untested):
- zpool create tank mirror dev1 dev2 dev3
- zpool export tank
But this will unmount all the file systems, right?

Presumably, zpool import.
This is basically what everyone does today with mirrors, isn't it? :-)
