Zpool error but online

[fede2222]

Hi

Today i recreate a pool and copy a lot of data... in a break i opened the GUI and see a yellow status... So.. zpool status

Code:

[root@freenas] ~# zpool status media6
  pool: media6
 state: ONLINE
status: One or more devices has experienced an unrecoverable error.  An
        attempt was made to correct the error.  Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
        using 'zpool clear' or replace the device with 'zpool replace'.
   see: http://www.sun.com/msg/ZFS-8000-9P
  scan: none requested
config:

        NAME                                            STATE     READ WRITE CKSUM
        media6                                          ONLINE       0     0     0

errors: No known data errors

I'm doing a SCRUB now... this behavior is common when copying lot of data (4.1TB)?... or is a near problem on the future. The SMART data of the disk looks ok. DMESG not report lost device or anything after power on... Is there a way to look what can cause this error?, to avoid future problems.

Thanks

edit: During SCRUB (at 20%), i got something in DMESG

Code:

GEOM_ELI: Crypto WRITE request failed (error=5). ada3p1.eli[WRITE(offset=393216, length=65536)]
swap_pager: I/O error - pageout failed; blkno 1572963,size 65536, error 5
GEOM_ELI: Crypto WRITE request failed (error=5). ada3p1.eli[WRITE(offset=458752, length=65536)]
swap_pager: I/O error - pageout failed; blkno 1572979,size 65536, error 5
GEOM_ELI: Crypto WRITE request failed (error=5). ada3p1.eli[WRITE(offset=249856, length=8192)]
swap_pager: I/O error - pageout failed; blkno 1572928,size 8192, error 5

I don't have encryption on that pool... ¿?... ada3 is a HDD on the pool in question

ada3 is failing and should be replaced. Any errors from a zpool scrub are bad, and any write request failed is also a bad sign. Being that you have a raidz1 your "redundant" disk seems to already be failing, so you should replace it before that disk fails along with another. This happens so frequently its why I don't recommend RAIDZ1 unless you are doing religious backups.

Thanks Cyberjock... ADA3 is the GptId that have Write and Checksum errors. I will replace it...

I wish to have ZFS2, but to do this i need to move the data somewhere (new disks) and buy new disks for the extra spare, money for me is an issue. I know the speech of how much value your data, but my economic status dont allow me to do it. It's a home installation. So i cant move to ZFS2 in the short term. It's catharsis.. not any problem with you Cyberjock, you always help people in the forum.
