Hi List,
A few weeks ago I created a Raid 5 set for my data partition using mdadm.
This works fine, but last week a short power outage caused the server to
reboot.
When I came home the server was in need of maintainance because it couldn't
check all his filesystems.
Strange fact was that the md device wasn't start...
mdadm --assemble /dev/md1 works fine, the /etc/mdadm.conf is read the the
raid device is started...
But why doesn't start it at boot?
A piece of output from dmesg:
md: Autodetecting RAID arrays.
md: autorun ...
md: considering hdb1 ...
md: adding hdb1 ...
md: created md1
md: bind<hdb1>
md: running: <hdb1>
raid5: device hdb1 operational as raid disk 0
raid5: not enough operational devices for md1 (2/3 failed)
RAID5 conf printout:
--- rd:3 wd:1 fd:2
disk 0, o:1, dev:hdb1
raid5: failed to run raid set md1
md: pers->run() failed ...
md: do_md_run() returned -5
md: md1 stopped.
md: unbind<hdb1>
md: export_rdev(hdb1)
md: ... autorun DONE.
It tell's me that 2/3 devices failed, but after I assemble it.. the ouput of
mdadm --detail /dev/md1 is:
/dev/md1:

If UNIX isn't the solution, you've got the wrong problem.
