[1.] Using raid0,1 moduls not possible in kernel 2.2.16
[2.] The following problem was found on two different systems. we can't use the
kernel 2.2.16 for we are using software raid0
mounting a /dev/md device (either raid0 or raid1, i've checked) is not
possible in Kernel 2.2.16.
raid's were used with 2.0.36 and 2.2.13-2.2.15 without any problems.
creating:
mdcreate -c8k raid0 /dev/md0 /dev/sdb1 /dev/sdc1
mdadd -a
mdrun -a
mount /dev/md0 /mountpoint
mdcreate -c4k raid1 /dev/md1 /dev/sdd1 /dev/sde1
mkraid << EOF
# Mirror Raid configuration /dev/md1
raiddev /dev/md1
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
device /dev/sdd1
raid-disk 0
device /dev/sde1
raid-disk 1
EOF
mdadd -a
mdrun -a
the following was done with the raid0:
during mount the following essage appeared endless, stopping not possible:
REGISTER_DEV sdb1 to md0 done
REGISTER_DEV sdc1 to md0 done
raid0 : Allocating 8 bytes for hash.
VFS: grow_buffers: size = 65536
VFS: grow_buffers: size = 65536
VFS: grow_buffers: size = 65536
VFS: grow_buffers: size = 65536
VFS: grow_buffers: size = 65536
VFS: grow_buffers: size = 65536
VFS: grow_buffers: size = 65536
VFS: grow_buffers: size = 65536
VFS: grow_buffers: size = 65536
......
we tried it a few times, and the grow_buffer size changed between 8192,
65536 and 131072
