Yes, the devid should have prevented this from occurring in the first
place.  One interesting thing would be to run 'zdb -C' and see if the
devid of the disk is now different from the email you sent previously.

It is. Previously:

guid=12723054067535078074
path='/dev/dsk/c1t0d0s7'
devid='id1,[EMAIL PROTECTED]/h'

whereas now:

guid=12723054067535078074
path='/dev/dsk/c1t0d0s7'
devid='id1,[EMAIL PROTECTED]/h'

So everything looks the same but the devid has changed. Is this
a consequence of having changed the raid controller?

Hm. I tried this earlier, and it didn't work. (Pretty much the first thing
I tried). Something like 'no such pool' when I tried the export.

However, I just tried again and it worked. But I have been poking at it and
it's had a reboot or two along the way.

So thanks - I have my data back!

There must be a better way of handling this. It should have just
brought it online first time around, without all the fiddling around
(that feels like voodoo to me).

2007-09-13 Thread Solaris 
Ok, I guess I misunderstood the status of your pool.  If you can do a zpool
status then your zpool is configured, and should be exportable, even if the
pool is inoperable, right?  If you do a zpool status and it says no pools
available (just like the zpool import command you had shown), then my
suggestion would not be applicable to your situation.

Greetings,

It looks to me like maybe the device names changed with the controller
swap you mentioned.  Possibly the "new" device has not been fully
recognized by the OS yet.  Maybe a "cfgadm -al" will trigger a rescan
of disk devices, and/or show if anything is awry.

Once you've confirmed that the OS actually sees the disks, you might
try removing /etc/zfs/zpool.cache and then doing "zpool import".

Regards,

Marion

The pool is imported, or else 'zpool status' wouldn't show it at all.
It's just faulted.  So when you say "doesn't work", does that mean that
the "zpool export" failed, or that it doesn't find the pool when doing
the subsequent "zpool import"?

Not yet. Let me give it a try:

# zpool clear storage
cannot open 'storage': pool is unavailable

Bother...

Thanks anyway!

Doesn't work. (How can you export something that isn't imported
anyway?)

[zfs-discuss] How do I get my pool back?

2007-09-13 Thread Peter Tribble 
After having to replace an internal raid card in an X2200 (S10U3 in
this case), I can see the disks just fine - and can boot, so the data
isn't completely missing.

However, my zpool has gone.

# zpool status -x
  pool: storage
 state: FAULTED
status: One or more devices could not be opened.  There are insufficient
replicas for the pool to continue functioning.
action: Attach the missing device and online it using 'zpool online'.
   see: http://www.sun.com/msg/ZFS-8000-D3
 scrub: none requested
config:

NAMESTATE READ WRITE CKSUM
storage UNAVAIL  0 0 0  insufficient replicas
  c1t0d0s7  UNAVAIL  0 0 0  cannot open

Note that this is just a slice on my boot drive. So the device
is physically accessible.

How do I get my pool back?

(And how can this sort of thing happen?)

# zpool import
no pools available to import

# zdb
