If it keeps up the reshape rate, it will complete in 4ish days. That's still a long time for it to sit there with a potentially bad drive. Can you cancel the reshape and just replace the failing drive and have it rebuild it, then reshape it after?

Could you point me to the command to cancel the reshape?
So the steps would be, mark the failing drive as failed, remove it from the array, replace it physically, format new drive, and start the array again. At that point, you're thinking it should rebuild using the new drive, then continue reshaping to the other 2 drives after that?

Yeah, mdadm --S /dev/md0 will stop the array. I didn't know if there was another specific command to simply stop rebuilding. I will have to mark the drive as failed and remove it from the array before I stop the array though. I'll try this all later or tomorrow morning and see how things work out.
Good luck!

Maybe one of the disks (the failing one?) is slowing all others down. The hdparm program might give an indication:
etc.Code:hdparm -tT /dev/sda
What could help in such a case, is copying all data from the failing disk to a new healthy disk and continue from there (I'm not sure what happens when you cancel the reshape/resync/recover.)
The right tool to do that is ddrescue.
Thanks for all of your suggestions so far everyone! Funny thing...I woke up this morning, and the array was just about finished reshaping. Go figure, right? The drive 'sdi' is still failing, but I came back from being out all day and the array is now clean, active, and rebuilding to the other two drives:
Still won't mount though...Code:Every 2.0s: cat /proc/mdstat Sun Sep 29 16:56:42 2013 Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : active raid6 sdh1[0] sdk1[11] sdl1[12] sdj1[9] sde1[7] sdb1[6] sdf1[5] sdd1[4] sdg1[3] sdc1[2] sdi1[1] 8790839424 blocks level 6, 64k chunk, algorithm 2 [11/9] [UUUUUUUU_U_] [>....................] recovery = 4.1% (40822148/976759936) finish=1234.2min speed=12638K/sec unused devices: <none>
Wait for it to rebuild and see if it will mount.

I've changed out the bad drive to a new good one and it recovered! Hooray.
Same problem still around though, that the drive won't mount (same error). Thoughts?
Aw crap. Have you run fsck on the md0 device?
