Recently my data drive of 6tb was disabled. My two parity drives were 22TB and 24tb. I had a new 26tb drive so had to do parity swap.

Everything seems fine so I started to copy as per instructions.

However it has almost been 12 hours and it is still at 1%, and I don’t see any increase in numbers for reads and writes count between 22tb and 26tb drive. Something is wrong..? Is it supposed to be like this? How can I restart the process without breaking anything?

There's a call trace logged less than one minute after the parity copy started, so it's very possible it crashed the copy.

You using a very old release, I would recommend upgarding to latest (backup the flash drive first), then try the procedure again.

I didn’t want to upgrade now while there is an issue.. unless the os cannot support 26tb... will I be able to copy it still if I cancel it now and I start it again? I’m just worried it won’t know to provide me the copy option anymore.

That's not a problem, but it may be related to other hardware. You can try again with the same release, but upgrading with disabled disks is not more risky than with enabled ones, though, like mentioned, create a flash backup first.

You should be able to start a new copy after a reboot.

Ok I tried to click reboot but it seems like it didn’t take. I went back and click Cancel also nothing happened. Typing command reboot does nothing too. Any idea what is going on? Should I force power off?

If normal shutdown doesn't work, you will need to.

Forced reboot and had to set the disks again and then it was thankfully fine afterwards and it ran as expected! Once parity copy was done it rebuilt and all is fine. Thank you!
