Hello,
I need some advice with a pool where multiple hard disks are showing signs of failure.
The first disk began to show signs of failure a few days ago with 198 Offline Uncorrectable count increasing after a failed SMART test.
I have offlined this disk and already installed its replacement, which is now completing its final smart test after badblocks.
Now, while badblocks was running on the replacement, two more disks (out of a total of eight in a raidZ2) are starting to exhibit the same problem: 198 Offline Uncorrectable count increasing. The pool is currently in a degraded state, but still healthy. I almost cannot believe the amount of chance I ran into (3 out of 8 disks starting to fail within 3 days).
What is the best course of action now? I'm thinking to start to re-silver the replacement disk and cross my fingers that the other two don't give up on me?
Or would it be more advisable to just tear down the pool, replace all three disks and restore from backup? Other thoughts?
Thanks,
