Hi guys,
I have a quick question, I am playing around with ZFS and here's what I did.
I created a storage pool with several drives. I unplugged 3 out of 5 drives
from the array, currently:
NAME STATE READ WRITE CKSUM
gpool UNAVAIL 0 0 0 insufficient replicas
raidz1 UNAVAIL 0 0 0 insufficient replicas
c8t2d0 UNAVAIL 0 0 0 cannot open
c8t4d0 UNAVAIL 0 0 0 cannot open
c8t0d0 UNAVAIL 0 0 0 cannot open
These drives had power all the time, the SATA cable however was disconnected.
Now, after I logged into Solaris and opened firefox, I plugged them back in to
sit and watch if the storage pool suddenly becomes "available"
This did not happen, so my question is, do I need to make Solaris re-detect the
hard drives and if so how? I tried format -e but it did not seem to detect the
3 drives I just plugged back in. Is this a BIOS issue?
Does hot-swap hard drives only work when you replace current hard drives
(previously detected by BIOS) with others but not when you have ZFS/Solaris
running and want to add more storage without shutting down?
It all boils down to, say the scenario is that I will need to purchase more
hard drives as my array grows, I would like to be able to (without shutting
down) add the drives to the storage pool (zpool)
Thanks
