Having a problem with our Freenas box.
Our server is a Supermicro X7DBE+ Dual L5420, 16GB RAM, LSI 9211-8i. We are using 8x Seagate 2TB Barracuda ST2000DM001 drives. From the boot process, it says it's FreeBSD-RELEASE-p4 #0 r262572+17a4d3d
On boot it says:
after sitting there for a few minutes, it reboots.
We had an issue a few weeks back where the freespace ran out. I was able to clear that up and the server was working fine. The other day, I happen to be on the server, and noticed the alerts indicated one of the drives was bad. It had no errrors, just reporting it had some retries on it from what I could remember. I attempted to go into the GUI to see if we bring the disk offline and use the spare disk to rebuild while the "bad" disk is replaced. I remember being able to pull teh information up, and seeing the option to edit/offline the disk. Wasn't quite sure, and decided I would handle this when I was back at the office. When I came back to the office, I was not able to see any of those options in the GUI. After a reboot, the system gets stuck, at a point where it is looking for l2arc_no_rw. If I disconnect the drives, the system boots, but of course complains about missing volume1.
I was wondering if there's a way of clearing the volume from the freenas system through the shell, and attempt to reimport the pool. I've come to grips with the fact that our pool may be done. However, I'd like to see if anything is possible to attempt to recover the data. It's mostly off-site backups, so it's just a matter of re-seeding the backups. Would prefer to not, but if we must, we must.
Thanks,
Carlos.
