This seems to be a semi-common issue asked, but I have not yet found a good solution.
I try the following:
[root@localhost ~]# pvcreate /dev/sdc
Can't open /dev/sdc exclusively. Mounted filesystem?
This forum post shows the user's solution to have been to boot off a different image, modify his LVM groups, and then restart normally.
That is not an option for this particular setting.
Output of multipath -l
:
[root@localhost ~]# multipath -l

What do I need to do to get past this issue?
mount | grep sdc
return nothing, and lsof | grep sdc
shows only multipath
looking at it (which makes sense since it's a LUN).
