As an alternative, assuming omconfig doesn't work for some reason and
dellmgr doesn't have the functionality...an (unpleasant) alternative
would be to brute-force copy everything off the host, rebuild the array
from scratch, and copy everything back. Sorry if this is a bit
off-topic, but does this look like a good synchronization command?
rsync -a --hard-links --sparse / /external_backup/tempfs
The restore command would be the same arguments, but the directories
reversed:
rsync -a --hard-links --sparse /external/backup/tempfs/ /
(Note the absence and presence of the / after tempfs, which I believe
is significant to rsync.)
I'm also open to other solutions using tools other than rsync (tar,
perhaps?). The basic idea is that I want the filesystem to look
exactly the way it did before the copy.
