mdadm: Cannot open /dev/hdb5: Device or resource busy
All the solutions I've been able to google fail with the busy. There is
nothing that I can find that might be using /dev/hdb5 except the raid
device and it appears it's not either.
Very odd. But something must be using it.
What does
ls -l /sys/block/hdb/hdb5/holders
show?
What about
cat /proc/mounts
cat /proc/swaps
lsof /dev/hdb5
??

Problem is not raid, or at least not obviously raid related. The
problem is that the whole disk, /dev/hdb is unavailable.
root@chinaberry:~# for i in /dev/hdb?

mount: /dev/hdb1 already mounted or /mnt busy
mount: /dev/hdb2 already mounted or /mnt busy
mount: /dev/hdb3 already mounted or /mnt busy
mount: /dev/hdb4 already mounted or /mnt busy
mount: /dev/hdb5 already mounted or /mnt busy
mount: /dev/hdb6 already mounted or /mnt busy
root@chinaberry:~# mount /dev/hda1 /mnt
I can fdisk it but none of the partitons are available. Knoppix can
access it normally so it's not a hardware issue. No funny messages in
the syslog. So I'll go off and stop harassing this list. ;)
Thanks,
Jim.
