zfs discuss - Sep 2010 - How to rebuild raidz after system reinstall

What does ''zpool import'' show?  If that''s empty, what
about ''zpool import
-d /dev''?

I just tried

admin$ zpool replace BackupRAID /dev/disk0 /dev/disk1 /dev/disk2
too many arguments

As you can see, it didn''t do what I need to accomplish.

I think, I just destroyed the information on the old raidz members by doing

zpool create BackupRAID raidz /dev/disk0s2 /dev/disk1s2 /dev/disk2s2

The pool mounted fine after that, but is empty. None of the old information is
present. Am I right?

It should have warned you that two of the disks were already formatted 
with a zfs pool.  Did it not do that?  If so, perhaps these aren''t the 
same disks you were using in your pool.

There was no warning. This is the output:

admin$ sudo zpool create BackupRAID raidz /dev/disk0s2 /dev/disk1s2 /dev/disk2s2
Password:
admin$ zpool status
  pool: BackupRAID
 state: ONLINE
status: The pool is formatted using an older on-disk format.  The pool can
	still be used, but some features are unavailable.
action: Upgrade the pool using ''zpool upgrade''.  Once this is
done, the
	pool will no longer be accessible on older software versions.
 scrub: none requested
config:

	NAME         STATE     READ WRITE CKSUM
	BackupRAID   ONLINE       0     0     0
	  raidz1     ONLINE       0     0     0
	    disk0s2  ONLINE       0     0     0
	    disk1s2  ONLINE       0     0     0
	    disk2s2  ONLINE       0     0     0

errors: No known data errors

I can only tell you what it is now:

admin$ zpool import
no pools available to import
admin$ zpool import -d /dev
no pools available to import

Also, I am quite sure that I was using the actual drives from the old raidz.
This is my drive listing:


admin$ diskutil list
/dev/disk0
___#:_______________________TYPE NAME____________________SIZE_______IDENTIFIER
___0:______GUID_partition_scheme________________________*465.8 Gi___disk0
___1:________________________EFI_________________________200.0 Mi___disk0s1
___2:________________________ZFS BackupRAID______________465.4 Gi___disk0s2
/dev/disk1
___#:_______________________TYPE NAME____________________SIZE_______IDENTIFIER
___0:______GUID_partition_scheme________________________*465.8 Gi___disk1
___1:________________________EFI_________________________200.0 Mi___disk1s1
___2:________________________ZFS BackupRAID______________465.4 Gi___disk1s2
/dev/disk2
___#:_______________________TYPE NAME____________________SIZE_______IDENTIFIER
___0:______GUID_partition_scheme________________________*465.8 Gi___disk2
___1:________________________EFI_________________________200.0 Mi___disk2s1
___2:________________________ZFS_________________________465.4 Gi___disk2s2

/dev/disk2 is the new drive.
