You'll have to make sure that disk is (1) not mounted anywhere, (2 - lvm specific) not a pv of any vg with at least one active lv, and (3) not a member disk of any running software raid device, (4) not otherwise "locked - in use" by other kernel systems like evms, iscsi, nbd, or others. (1) is solved by careful use of umount. (2) is solved by careful use of lvchange -an or vgchange -an (3) is solved by careful use of mdadm -S (4) is solved using tools specific to that kernel system. Unless you are using it for some vital filesystem, you should be able to fix you issue with rebooting. -- Boyd Stephen Smith Jr. ,= ,-_-. =.
