I had some more bright ideas and here is what happened:
I am unable to even do ls on the directory mounted on this raid device.
So, I said, maybe the problem is that I need to run fsck.ext3 on the drive
first. So I tried to umount it and i got the error message:
A1:~# umount /home/big0
umount: /home/big0: device is busy
umount: /home/big0: device is busy
So I said maybe the problem is the rsyncing. So maybe an idea is to fail the
new added device /dev/hdi1 and then remove /dev/hdi1, move back to degraded
mode. Do an umount of the drive, then do an fsck.ext3 on the drive and then I
can do a reboot and then add the drive back in.
Hey why not?
Ok. So I tried: Here is the transcipt of the session:
