Hi,
I have encountered the following problem with a software raid array,
and I am hoping that you can help. I hav a Dell 410 with 2 SCSI busses,
each with 8 disk (16 in all). I configured the system as 2 raid 5
disk, md0 and md1, each with 7 data disks and 1 parity disk. Raid
disk md0 containd devices (sda1-sdh1) and md1 contained devices
(sdi-sdp1). Both raid arrays were OK until I moved the disks that
make up md0 to another computer. Naturally the naming of md1 has
changed. the disks that make it up have moved from sdi-sdp to sda-sdh.
I get the following message when I boot the system. As you can see the
raid autodetect does recognise that the disks have changed their names,
but fails to recreate the raid device md1????? Any help is appreciated.
Would a mkraid --force command with a new correctly composed raidtab
solve my problem? How about the raidreconf patch?
Thanks,
-Andy
