Hi,
I am seeing unexpected behavior with getting LVM drives to automatically mount when I boot my machine. The expected behavior works for one LV but not the other. I specified these lines in my /etc/fstab:
/dev/mapper/vg0-www /www ext3 rw 0 2 /dev/mapper/vg0-uml /uml ext3 rw 0 2
These entries didn't work, so I thought I'd try these next two lines:
/dev/vg0/www /www ext3 rw 0 2 /dev/vg0/uml /uml ext3 rw 0 2
Oddly enough, the uml disk mounts on bootup, while the www one does not! Is it just me, or is this chain of events, rather unexpectedly strange:
# umount /uml
# mount /dev/vg0/www
mount: wrong fs type, bad option, bad superblock on /dev/vg0/www,
or too many mounted file systems
# ls -al /dev/vg0/www
lrwx------ 1 root root 19 Nov 26 01:29 /dev/vg0/www -> /dev/mapper/vg0-www
# mount /dev/mapper/vg0-www /www
#
But:
# mount /dev/vg0/uml #
After this, both drives are mounted:
# df Filesystem 1K-blocks Used Available Use% Mounted on [my other partitions] /dev/mapper/vg0-www 30237648 10572760 18128888 37% /www /dev/mapper/vg0-uml 10079084 945240 8621844 10% /uml #
I am running Linux 2.6.8 on an Athlon with LVM on top of software RAID5. Both partitions were created with mkfs -t ext3 (i.e. no special options...at least...I don't remember using any special options...). I uncommented the "uml" line from /etc/fstab and rebooted, and saw the same sort of behavior. Any ideas? Feel free to email me for more info.
[side question: why is there a symbolic link from /dev/X/Y to /dev/mapper/X-Y anyway?]
Any and all advice is greatly appreciated!
Thanks,
- Armen
