zfs discuss - Jan 2011 - ZFS root clone problem

(for some reason I cannot find  my original thread..so I''m reposting
it)

I am trying to move my data off of a 40gb 3.5" drive to a 40gb 2.5"
drive.  This is in a Netra running Solaris 10.

Originally what I did was:

zpool attach -f rpool c0t0d0 c0t2d0.

Then I did an installboot on c0t2d0s0.

Didnt work.  I was not able to boot from my second drive (c0t2d0).

I cannot remember my other commands but I ended up removing c0t2d0 from my pool.
So here is how it looks now:

# zpool status -v
  pool: rpool
 state: ONLINE
 scrub: none requested
config:

        NAME        STATE     READ WRITE CKSUM
        rpool       ONLINE       0     0     0
          c0t0d0s0  ONLINE       0     0     0

zfs list shows no other drive connected to the pool.

I am trying to redo this to see where I went wrong but I get the following
error:
zpool attach -f rpool c0t0d0 c0t2d0


# zpool attach -f rpool c0t0d0 c0t2d0
invalid vdev specification
the following errors must be manually repaired:
/dev/dsk/c0t2d0s0 is part of active ZFS pool rpool. Please see zpool(1M).
/dev/dsk/c0t2d0s2 is part of active ZFS pool rpool. Please see zpool(1M).


How can I remove c0t2d0 from the pool?

Hi Alex,

Disks that are part of the root pool must contain a valid
slice 0 (this is boot restriction) and the disk names that you
present to ZFS for the root pool must also specify the slice
identifier (s0). For example, instead of this syntax:

# zpool attach -f rpool c0t0d0 c0t2d0

try this syntax:

# zpool attach rpool c0t0d0s0 c0t2d0s0

Then, apply the boot blocks to c0t2d0s0.

This issue was a bug in previous releases:

  # zpool attach -f rpool c0t0d0 c0t2d0
invalid vdev specification
the following errors must be manually repaired:
/dev/dsk/c0t2d0s0 is part of active ZFS pool rpool. Please see zpool(1M).
/dev/dsk/c0t2d0s2 is part of active ZFS pool rpool. Please see zpool(1M).

To workaround this bug, try this syntax:

# zpool attach -f rpool c0t0d0s0 c0t2d0s0

Thanks,

Cindy

Hey Cindy...

wanted to post up on here since you''ve been helping me in email (which
I greatly appreciate!).


I figured it out.. I''ve done the ''dd'' thing before
etc.  I got it all the way to where it was complaining that it cannot use a EFI
labeled drive.  When I did a prtvtoc | fmthard on the drive, I was never able to
change it to a SMI label.  So I went in there, changed the cylinder info,
relabeled, changed it back, label..and voila..now I can mirror again!!

Thank you for taking the time to personally email me with my issue.

-Alex
