I am having a problem getting my software raid setup. I have a system
running off an IDE hdd. I have an future domain ISA scsi card hosting 7
1gig scsi drives. The scsicard and Linux detect all the drives just
fine and they are all accesible through fdisk and such. The system is
running linux 2.2.12 and has support for multiple devices compiled in.
This is debian potato (updated slink) using the raidtools2 package. I
want to setup this system with the drives either linear or with RAID0
striping. (All 7 drives together).
The problem I am having comes when I want to mkraid. I have my setup
defined in /etc/raidtab which is attached to this email. When I run mkraid
/dev/md0 I get the message that it had to abort and it tells me to look in
/proc/mdstat and /var/log/syslog for possible clues. Syslog says nothing.
mdstat tells me that md0 -> 3 are inactive, read-ahead is not set, and
Personalities [1 linear] and [2 raid0]. This doesnt tell me much. I would
assume that md0 is inactive because I have not mkraid'd it yet.
Here is what I have done so far. All the drives are accessible. All of
them have a partition (1) that is marked type 0xfd (Linux raid
autodetect). None of them have ext2 filesystems on them anymore. They have
all been formatted msdos just so there would be no trailing superblocks.
When I get the raid going, I would like to make /dev/md0 ext2 and put
files on it.
So basically, why is mkraid complaining? Have I missed a step? Any help
would be appreciated.
Thanks,
Jon Webb
