Dear community
It's still a learning process for me, as I shall demonstrate now:
I am running a RAIDZ2 on a DELL R510 with a crossflashed H200. Today, my RAIDZ2-Pool was marked degraded, there were some write errors in one disk.
My plan was (and is) to get a replacement for this disk and resilver the pool (as I have done before). To make sure (now comes the beginner part :) ) there's nothing wrong with the backplane or some cabling, I shut down the server and took a look at the failing harddrive, the backplane and generally my server.
I then restarted and now there's a problem: FreeNas keeps trying to resilver my Pool, all the disks (including the faulty one) are now online. The resilver process works it's way to 1% and starts again from 0%.
What should I do now in order to replace the failed disk? Can I replace a disk while the pool is resilvering? There are no SMART errors in any of the disks.
da7 is the failing drive..:
Thanks and kind regards
Alex
