Drive failing, how best to proceed (snapraid)

So SMART sent me two emails:
Device: /dev/disk/by-id/ata-WDC_WD40EFRX-68WT0N0_WD-WCC4E5PER6EA [SAT], 1 Currently unreadable (pending) sectors

Device info:WDC WD40EFRX-68WT0N0, S/N:WD-WCC4E5PER6EA, WWN:5-0014ee-2b874c60a, FW:82.00A82, 4.00 TB
And:
Device: /dev/disk/by-id/ata-WDC_WD40EFRX-68WT0N0_WD-WCC4E5PER6EA [SAT], ATA error count increased from 2 to 3

Device info:WDC WD40EFRX-68WT0N0, S/N:WD-WCC4E5PER6EA, WWN:5-0014ee-2b874c60a, FW:82.00A82, 4.00 TB

And SMART in OMV says it has some bad sectors, so not completely dead. However my daily SnapRAID cron job quit hashing at 15%, did not sync, but then did a scrub and reported 2342 file errors. Are the scrub file errors because the sync wasn't done? Email log attached.

How should I proceed? Get a new drive and run a fix command before attempting any more syncs? Disable daily cron so no syncs are attempted until new drive can be installed?

Thanks!

No replies so far. Can or should I replace the drive as described in the snapraid manual? Or can I use the plugin GUI to simply edit the physical drive that the bad volume is pointed to and then run a fix? Does the gui let you select which drive to fix?

I ended up replacing two drives. I found it super easy to use the plugin GUI to edit the drive information to point to the new drive. I had spare empty hard drive slots, so it went like this:

• insert new drive, format and mount it.
• use snapraid gui to edit drive entry for bad drive to point to new drive
• run snapraid fix. Can either use plugin gui or shell. I prefer using a shell for these type of commands that will run for hours. If i use the web gui, when i come back my login will have timed out and I cant see what happened.
• run a check if you want, or sync and you're done
• old drive will be unreferenced at this point so it can be wiped, unmounted, and removed.
