Is RAID1 alive and well?
Etch with kernel 2.6.12-1-686 (2.6.12-10) Gnome desktop
........................................................
I recently tested imaging and restoring my complete system with Mondo
(before I screw it up again :-)
All seems well, but earlier today I thought I saw something like "RAID1
not detected" in the messages scrolling by at boot up. May be nothing,
as I have scanned all logs in the appropriate time frame without
success, but I would like to put my mind at rest. I've been googling
and searching man pages for hours for a way to determine if RAID1 is
working properly after the restore. I even installed a package named
"dmraid" which tells me there is no detected RAID, but I'm not sure it's
looking for the type of software RAID used by Debian.
The only thing I found (other than dmraid) that gives me any kind of
indication is the cli "sfdisk" (I only used the -l option). The output
from such is below. Is it telling me that hdb is an "active" RAID1
disk? Is there any other way of determining the status of RAID1 in my
Debian installation? Sorry, but this is bugging me %-/
Thank you,
Lee C
