I am having a problem with SLES 10 where it will not always boot
because it is unable to find any of the file systems that are using
EVMS. I am running under z/VM 5.3 and using mini disks. All are using
ext3 as the file system. When I have this problem I can usually reboot
and it will start correctly.
I have installed using the following DASD configuration all on 1
physical mod 9 volume:
0201 ROOT 1004 Cyl /
0202 EVMS 1004 Cyl /home/
0203 EVMS 3000 Cyl /opt/
0204 EVMS 3000 Cyl /usr/
0205 EVMS 1004 Cyl /tmp/
0206 EVMS 1004 Cyl /var/
When I receive the boot failure I see the following messages in
my log:
error on stat() /dev/evms/lvm2/home/home: No such file or
directory
error on stat() /dev/evms/lvm2/opt/opt: No such file or
directory

The superblock could not be read or does not describe a correct
ext2
filesystem. If the device is valid and it really contains an
ext2
filesystem (and not swap or ufs or something else), then the
superblock
is corrupt, and you might try running e2fsck with an alternate
superblock:
e2fsck -b 8193 <device>
fsck.ext3 /dev/evms/lvm2/home/home failed (status 0x8). Run
manually!

Any ideas why I am receiving these messages and how to fix it so
it will always boot properly. I do need to have EVMS or lvm for the file
systems and would prefer EVMS.
