I have two enterprise-grade SSDs that I've been using for
L2ARC in an
OpenZFS pool for a few years. Workflow during this time has been fairly heavy, with lots of reads and writes, serving up video to clients for video post-production.
Recently, got a couple of critical alerts about the L2ARC SSDs:
CRITICAL: Oct. 22, 2018, 6:12 p.m. - Device: /dev/da0 [SAT], 215869351264256 Offline uncorrectable sectors CRITICAL: Oct. 22, 2018, 6:12 p.m. - Device: /dev/da1 [SAT], 174264003067904 Offline uncorrectable sectors
Obviously there's no risk of data loss, since these are just L2ARC, but is it time to just get them replaced?
Am I sacrificing performance? If not, is there a way to reset or ignore the bad sectors?
