zfs discuss - Sep 2010 - moving rppol in laptop to spare SSD drive.

Hello folks,

I ordered a bunch of 128Gb SSD''s the other day, placed 2 in PC, another
in a windoz laptop and I thought I''d place one in my opensolaris
laptop, should be straightforward or so I thought.

The problem I seem to be running into is that the partition the rpool is on is
130Gb, SSD once sliced up is only about 120Gb.

I pulled the main disk from the latop and put it in a caddy, put the new ssd in
the drive bay and booted from cdrom.

I imported the rpool and created an altpool on the ssd drive.

zfs pool list shows both pools.
altpool size 119G avail 119G
rpool size 130G used 70G

I created a snapshot of the rpool and tried to send it to the other disk but it
fails with file too large.

zfs send -R rpool at backup > altpool
warning: cannot send ''rpool/build at backup'': file too large.

is there anyway to get the data over onto the other drive at all?

Thanks Steve.

Hi Steve,

Couple of options.  

Create a new boot environment on the SSD, and this will copy the data over.

Or 

zfs send -R rpool at backup | zfs recv altpool

I''d use the alt boot environment, rather than the send and receive.

Cheers,
-Mark.

Doh,

Why didn''t I think of that cheers Mark, some time the most obvious
options get completely passed by, alt boot environment it is.

Thanks Steve.

You can create a new pool on the replacement drive and use send | recv
to populate it.

There are a few properties that are normally set on a boot pool,
namely bootfs, which points at your bootenv:
$ zpool get bootfs rpool
rpool  bootfs         rpool/ROOT/snv_134  local

The basic method is:
- Boot from LiveCD
- Import existing rpool. You may need to import -f.
- Using fdisk, create a SOLARIS2 fdisk partition that uses the entire drive.
- Using format, create slice 0 that uses the entire disk.
- Create new rpool in slice 0 (call it "new_rpool"?)
- zfs send -R rpool | zfs recv new_rpool
- BOOTFS=$( zpool list -o bootfs -H rpool )
- zpool export rpool
- zpool export new_rpool
- zpool import new_rpool rpool (to rename it to rpool)
- zpool set bootfs=$BOOTFS
- zpool export rpool
- Run installgrub on the new drive
- Powerdown, remove the old drive and boot.
- Profit.
