[SOLVED] ZFS has detected an io error: Mail from PVE

[fireon]

After the last 2 weeks i get about 7 Mail from Errors from us Backupmachine:

 eid: 7
 class: io
  host: backup
  time: 2016-10-27 20:35:23+0200
 vtype: disk
 vpath: /dev/disk/by-id/ata-WDC_WD20EARX-00ZUDB0_WD-WCC1H0381420-part2
 vguid: 0x3F2DB389837D114B
 cksum: 0
  read: 0
 write: 0
  pool: rpool

Always the same disk. But smarts seems to be ok:

OK - Powered on: 35103 hours, Power cycles: 236, Reallocated sectors: 0, Reallocated events: 0 (was 0 during discovery: normalized value looks OK), Spin retries: 0, Pending sectors: 0, UDMA CRC errors: 0

So what does it mean? I scrubed the pool a few days ago. No errors.

Thanks

That system has been online for 4 years? Nice. Why not replace the drive?

... smart finds no errors, and it is only an backupserver, so that is the reason. Scan ZFS the disk with another way?

 

[fabian]

does the journal at those timestamps show any error messages?

Bad WDGreen. Only use WD Red Pro or Enterprise SSD's
