The monthly data check found a bad drive in my raid6 array. This is what
started to show up in the log:
Jun 3 12:02:53 rogen kernel: [9908355.355940] sd 2:0:1:0: attempting task abort! scmd(ffff8801547c6a00)

But now it has changed to this:

I don't really want to wait 30 days for this to finish, what is correct
thing to do before I replace the failed drive?
Thanks in advance,
