Re: A Nasty md/raid bug

26 June 2012, 23:29 UTC

Any thoughts on sorting this out when the (Ubuntu) system in question has whole-disk encryption at boot stacked on top of the raid (and LVM on top of that)?

There are actually 2 partitions mirrored by raid in this case -- a small one with /boot installed (no encryption) and a larger one with /swap and an encrypted LVM volume containing / .

Assuming the system were affected, if one were to move mdadm as suggested prior to shutting down, it wouldn't be possible to move it back after boot without mounting the encrypted disk and LVM volume via busybox/cryptsetup or a rescue disk, but wouldn't these be on the inaccessible array and therefore... inaccessible?

Thanks for any thoughts you may be willing to share.
