- Hi Kris and Alan,
- Love the show. I'm not yet a full-time user of BSD but listening to this show is slowly converting me.
- What I do have right now is a FreeNAS box which I use to store family photos/videos and share via samba.
- My question is...
- Yesterday I had a bit of a scare as I saw ZFS reporting something like this:
- ----------------------------------------------------------------
- # zpool status -v
- pool: vol1
- 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.
- see: http://www.sun.com/msg/ZFS-8000-8A
- ...
- ----------------------------------------------------------------
- And a list of a bunch of videos of my kids listed after as corrupt files.
- My pool is a 2TBx3 (6TB total) stripe array.
- I switched the nas off and reseated the HDD's to see if that would help. Then I turned it back on and tried to copy files off to another PC (via samba). I got a read error and gave up then went back to look at FreeNAS again and even MORE files were listed as corrupt under zpool status.
- I was then about to give up and thought I would try a scrub to see if it would help (there was no redundency in the array so not sure if it could). After the 5 hour scrub though the result was this:
- ----------------------------------------------------------------
- pool: vol1
- state: ONLINE
- scan: scrub repaired 0 in 4h45m with 0 errors on Mon Feb 1 13:00:23 2016
- ----------------------------------------------------------------
- How is that possible the errors could fix themselves? I tried to view the corrupted files and they viewed fine.
