One of my disks has decided to die on me.
Its actually the newest of all of my disks, still under warranty, so it’ll probably be replaced with a new one.
But until I get this sorted out, I have ordered a new disk to replace it.
The symptoms are something like this.
Rockstor started sending me mails about pending writes to sdf.
I started investigating.
sdf is recognized in bios, and by rockstor.
“Btrfs fi sh” shows that its stil registered as part of the pool. The pool is not acessible, propably due to the reboot I made to see if it was detected by BIOS.
The disk is definately defective, its clicking every 1 second, and every few minutes it spins down and up again.
DMESG shows a lot of read / write and other errors.
In my time with Rockstor I have been installing and replacing a lot of disks. But never one that has gone defective.
The documentation seems a bit sketchy about this scenario.
Do I just run a btrfs replace (-r), or do I have to mount the volume in degraded mode, before replacing?
Anybody with any insights?
