Running FreeNAS for a couple years now. It is built on a Dell 390 workstation. I have 6Gb ECC RAM and have had no major issues to date. I have had a few minor problems and it was suggested that I go to 8Gb from 6Gb. It is a long story as to how hard it has been to find ram for this machine, but I finally received some and put it in yesterday. Powered down, pulled plug, removed the 2 sticks, replaced to bring it to 8Gb. Post shows 8Gb. Boot FreeNAS and it almost boots then has a kernel panic. Tried it again. same result. Powered down replaced the 2 sticks and replaced it with what I had previously (back to 6Gb). it boots up! Yea! now I have a critical error, though:
~# zpool status -v
pool: first_NAS
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

What is the best way to repair this? It doe snot appear that any of my data has been affected. Backup and wipe? Can/should I reinstall Freenas from scratch then use my config to restore the pool? It appeqars to be in the OS area and may affect any updated (python). There is also an update for it, but I have not clicked on it until I get this error resolved.

CRITICAL: The volume first_NAS (ZFS) state is ONLINE: One or more devices has experienced an error resulting in data corruption. Applications may be affected.
Ran zpool status -v and was initially told that there was an error in file '0x0'. Ran a scrub and now it says:
~# zpool status -v
pool: first_NAS
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.
