https://bugzilla.novell.com/show_bug.cgi?id=256183 ------- Comment #4 from nfbrown@novell.com 2007-04-12 16:52 MST ------- Both --examine and --examine-bitmap must be given a name of a component device, not the whole array. e.g. mdadm --examine-bitmap /dev/hda2 mdadm --examine /dev/hdc2 This is because the bitmap is stored on the devices. It is not stored in the array. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

https://bugzilla.novell.com/show_bug.cgi?id=256183 ------- Comment #5 from jnelson-suse@jamponi.net 2007-04-12 20:13 MST ------- My goodness. Somehow I've managed to miss that. Thank you for clarifying. If you happen to think of it, perhaps a small note or example in the manpage/docs might be warranted. Thank you for the explanation! I don't know if I should close the bug or not but surely the issue is one of operator error in any case. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
