Hi all, got some questions about ZFS filesystem on Ubuntu, some help would be great, thanks!
I used ZFS to create a storage pool on my Ubuntu system (12.04, 32bit) and has been using it as a file server for a few months now. Had a few hiccups - first, messed up Ubuntu so much that I had to do a reinstall, and then the OS drive just died last night, out of the blue, which has left my pool in a 'DEGRADED' state with some 'UNAVAILABLE' devices, as seen below:
According to some ZFS cheat sheets I've read, I should be able to remove cache devices from the pool but I just don't seem to be able to get rid of sdb7 and sdb6. Tried zpool replace and zpool remove, it said no such device in the pool when the output clearly says there is. My question is, is there any way to force remove these unavailable devices? Do I even have to remove them, considering there are other online devices in the same category? Is it bad to leave it in its degraded state?
Question 2, is it okay to add more drives controlled by a different chipset to this pool? My board only has 5 SATA ports and all are occupied right now. I can add a PCI/PCI E SATA card and thus more drives, but will this bring any compatibility issues with the existing pool? Would there be any huge performance issues?
Thanks in advance!

Code:
pool: server
state: DEGRADED
status: One or more devices could not be used because the label is missing or
invalid. Sufficient replicas exist for the pool to continue
functioning in a degraded state.
action: Replace the device using 'zpool replace'.
