I've got the new controller and the new system disks running in the
system, for anybody keeping score at home.
So I'm looking at how to migrate to the new system disks. They're a
different size (160GB vs 80GB) and form factor (2.5" vs 3.5") from the
old disks (I've got a mirrored pool for my old rpool).
Here's what I've started: I've created a mirrored pool called rp2 on
the new disks, and I'm zfs send -R a current snapshot over to the new
disks. In fact it just finished. I've got an altroot set, and
obviously I gave them a new name so as not to conflict with the existing
rpool.
I probably lost properties in the zfs send/receive (111b doesn't support
-p on zfs send). I suppose I could boot from a LiveCd of something
more recent and re-do the send/receive with a version that supports -p,
to save me trouble later reconstructing the properties.
So, I was thinking I could reconstruct the properties, rename the pool
and filesystem (possibly by booting from a livecd), and put Grub on them
the same way you do when adding a mirror disk to rpool. Other
possibilities seem to include using dd to copy one drive physically and
then booting from it and proceeding from there, and installing from
scratch on the new drives (and then having to recreate my configuration
down to UIDs and GIDs manually).
So does anybody have strong opinions about the best, meaning easiest,
way to do this, remembering that when done I need to import my existing
data pool and have the user still have access to their data?
I haven't actually investigated if the bios can boot from the new
controller, but if not I can finagle the cables around to put the new
disks on the old controller.
Speaking of which, to make the controller card physically fit I had to
remove the end bracket from it, since it didn't match up with the
cutouts in the back of the case. This leaves the controller almost
hanging free (currently supported by an inch of gaffer's tape), with one
now and soon two rather stiff SAS-to-4-SATA cable sets connected to it.
This seems like a bad idea, really. I suppose I could glue some wood
blocks to the back of the chassis (or the next covering strip down) to
provide something solid for the card to rest on, but being restrained in
both directions seems better. How do people handle this? And how did
this particular standard come to have competition?
