Hi,
I'm trying to create a linear RAID of two loopback devices. The code in the
standard 2.2.13 kernel acted very strangely, (sometimes it worked, mostly it
didn't) so I downloaded the raid0145-19990824-2.2.11 patch, and raidtools of
the same date.
However, I can't create /dev/md0 with the new raidtools... Can anyone spot
any errors here?
</scratch/raidtools-0.90> # cat ./raidtab
raiddev /dev/md0
raid-level linear
nr-raid-disks 2
persistent-superblock 1
device /dev/loop0
raid-disk 0
device /dev/loop1
raid-disk 1
</scratch/raidtools-0.90> # ./mkraid -c raidtab /dev/md0
handling MD device /dev/md0
analyzing super-block
disk 0: /dev/loop0, 563200kB, raid superblock at 563136kB
disk 1: /dev/loop1, 102400kB, raid superblock at 102336kB
/dev/md0: Invalid argument
</scratch/raidtools-0.90> #
Looking at an strace, this seems to be the problem:
open("/dev/md0", O_RDWR) = 4
ioctl(4, 0x400c0930, 0xbffff61c) = -1 EINVAL (Invalid argument)
