I did a replication to an extra disk as a backup, but I only did 1 dataset, I can't seem to replicate other datasets to it, so I assume it's a pool to pool thing or something... so I went to start over.

I tried to delete the dataset but it wouldn't do anything, so I removed the whole volume. I can't re-add the disk or wipe it due to the known issue... so I found the thread here and went to run the commands, but the last dd is not working.

Code:
[root@nas ~]# dd if=/dev/zero of=/dev/da3 bs=1m count=1

One of my 2 new disks that I moved everything to is flapping off/on and causing non-stop reslivering only to go offline and come back a few minutes later. I'm nervous to power down right now without a good backup, so I'm trying to get a snapshot and replication going to this other disk before I reboot, but having problems re-adding it.

What can I do to get past this so I can make this disk a fresh volume to replicate to?

Thanks

Well that's not good, I decided to add another disk back in, and dmesg shows it came online, but da4 never showed up in the GUI, now the last thing dmesg says is something about sending a reset to the controller 0 index 2 or something, but now nothing works, everything in the GUI just says "loading...". I tried to run gpart show on the console and it's just hanging too. apparently I should not have tried to connect another disk while the system was running, since the other disk keeps flapping on and off I thought it would be safe to do.

So at this point I can't seem to do anything at all in the GUI or shell. I can't pull up the GUI in a new tab at all either. Debating on pulling this disk I just tried to add back out... Really trying to avoid a hard power off at this point, all this to avoid shutting down the system while it was reslivering the original pair until I had a backup, maybe I should have just done it

That was stressful, I need to get a backup asap, that is clear...

The system was completely hung, would not even shutdown after getting a shutdown signal. I ended up hard booting the VM and thankfully the pool and datasets are still there and things seem OK.

Still interested to know how to fix my original problem so I can re-use that disk, for now I've put in an alternative disk to run a replication backup.

sigh lol... so I found out I have 2 more bad disks trying to find another to use for backup, I ended up putting the original backup that I replicated to and had the issue that started this tread back in. This time it failed to mount and said there was an error with the volume (even though I had deleted the volume before, it somehow came back, I assume that data at the end of the disk I was trying to remove...)... so I deleted it again, and suddenly I was able to wipe the disk, then I was able to re-use it without a problem.

Now to configure some backups to it, then configure some backups to backblaze!
