I have OpenSolaris 2009.06 currently installed on a 160 GB IDE drive.
I want to replace this with a 2-way mirror 30 GB SATA SSD boot setup.
I found these 2 threads which seem to answer some questions I had, but I still
have some questions.
Although, it seems possible to add a drive to form a mirror for the ZFS boot
pool 'rpool', the main problem I see is that in my case, I would be attempting
to form a mirror using a smaller drive (30GB) than the initial 160GB drive.
Is there an easy solution to this problem, or would it be simpler to just do a
reinstall of OpenSolaris 2009.06 onto 2 brand new 30GB SSDs? I have the option
of the fresh install, as I haven't invested much time in configuring this
OS2009.06 boot environment yet.
I also want the possibility to have multiple boot environments within
OpenSolaris 2009.06 to allow easy rollback to a working boot environment in
case of an IPS update problem. I presume this will not cause any additional
This is for a home fileserver so I don't want to spend too much, but does
anyone see any problem with having the OS installed on MLC SSDs, which are
cheaper than SLC SSDs. I'm thinking here specifically about wearing out the SSD
if the OS does too many writes to the SSDs.
I agree SSDs are a bit overkill, and using standard spinning metal would be
cheaper, but the case is vibrating like crazy as I ran out of drive slots and
had to use non-grommeted attachments for the boot drive. But the SSDs should be
silent and should certainly speed up boot and shutdown times dramatically :)
