Hi All,
I've got a problem with my software raid-1 setup that
I hope one of you kind people can help with. I have a slackware7.0
setup with an ide drive (for installation) and a pair of 9gig scsi drives
on an adaptec 2930 that will be used for the raid.
I can get the raid up by hand ok but I cannot get the system to boot
with raid entries in /etc/fstab - it errors saying
"Attempt to read block from filesystem resulted in short read
while trying to open /dev/md5"
"Could this be a zero length partition?"
But weirdly enough the first raid partition (/dev/md2, which
will be root) comes up fine.
The disks were both partitioned to have type fd and autodetect
raid is set in the kernel with the raid module hardwired.
Here's "raidtab", "fstab".
raidtab:
raiddev /dev/md2
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
persistent-superblock 1
chunk-size 4
device /dev/sda2
raid-disk 0

#/dev/md6 /newroot/usr ext2 defaults 1 1
#/dev/md7 /newroot/usr/local ext2 defaults 1 1
#/dev/md8 /newroot/home ext2 defaults 1 1
(This boots fine - uncommenting any of the other raid partitions
breaks it )
Thanks for any input - all help appreciated.
