Subject: how does autoraid work ?
Date: Tue, 28 Nov 2006 19:59:36 +0100 [thread overview]
Message-ID: <456C8718.2040406@goldfisch.at> (raw)
I've currently a new server (first ubuntu I set up) and I've a problem
with a raiddevice. While the system itself (/ and /boot) do not use
raid, a /data-partition is setup as raid1 /dev/md0
Now I'v the problem that md0 is not started during boot, but only late
when the scripts in rc.d/ are processed for my runlevel. There is a
script mdadm-raid that actually assemlnbles the raid based on a
copnfig-file. This is not what I want/need.
On my other servers the raids are autodetected much earlier by the
kernel or a module much earlier without need of a configfile.
The partitions of my raid are all labeld als linux-autoraid and I can
manually assemble my raid with mdadm -A -a yes -m 0 /dev/md0, so
everthing should be fine for the kernel to autostart my raid.
When exactely are the raids supposed to be assembled during boot. Which
module/script is actually responsible for doing this? And are there any
shots in the dark, why my ubuntu/debian is not doing so?
The raid is on hde and hdf - can this be the problem? that the
raidmodule/script/whatever does not scan beyond the first two ide-buses?
I tried raid=autodetect on the bootline but this didnt help either.
I hope I made my self a bit clear and any help is greatly appretiated...
thnx
peter
