Re: Help Root Raid

[Pankaj Agarwal]

Hi Ender,

this isn't the case...however i tried by changing the 83 to FD but it
doesn't worked.

its already enabled and the kernel is reading these partitions as well....i
guess because of these messages during bootup and shutdown....

Part of BOOTUP message ...
"
autodetecting Raid Arrays
autorun...
...autorun DONE
"

Part of shutdown message ....
"
md recovery thread got woken
md recovery thread finished
mdrecoveryd(7) flushing signals
Stopping all md devices.
"
Hope it helps you in helping me further.

thanks and regards,

Pankaj

Hello, Pankaj.

Probably you are not starting your RAID. You can check it with
cat /proc/mdstat. If not, well, you can mark the partitions forming the RAID
with persistent superblock (fd partition type in fdisk)) for starting
automatically the RAID on boot, or fill in the /etc/raidtab file with the
values of your current RAID and start it manually (see raidtools2 package).

Also you can read RAID-HOWTO for unvaluable information.

Regards,


Ender.
