Hey there,
So I am trying to replace the 6x3TB hard drives with 6x14TB SEAGATE ST14000NM002G drives. Last night I replaced a drive in the pool and left it to resilver overnight. Logging in this morning I can see the process is still running and I know this can take quite some time however I keep seeing the process get to about 22% or 23% and then it restarts from 0.
I have read some other posts and they seem to indicate that it can be due to errors on disks and not being able to rebuild properly. I have got two errors currently:
The mistake I think I have made is I should have replaced one of the disks with errors, instead I replaced da4 which was running fine.
Question: What should I do now, Ideally I would like to try and replace one of the drives with errors but I am worried to try that while the previous disk is still resilvering? Is there a way to safely stop this process and put back in the original da4 drive that was working and restart the whole process on da0 or da1?
Let me know if there is more information required and I'll post back as soon as I can.
