I have a SUSE 10 SP1 running on a HP proliant DL385 (VxVM 5.0MP3) that fails fsck during startup because it can't stat /dev/vx/dsk/dsudg/lvol1. If I comment out the volume in /etc/fstab and boot  the host, I can mount the volume without any problem. None of my other 5 SUSE host have showed this issue before. I suspect VxVM isn't fully stared but I can't find the reason.

Any ideas are greatly appreciated !.

Hello Nicolai, Was this ever

Hello Nicolai,

Was this ever working before ?

Also, was this disk encapsulated or manually added to group ?

From linux admin guide I see following:

Root disk encapsulation is only supported for devices with standard SCSI or
IDE interfaces. It is not supported for most devices with vendor-proprietary
interfaces, except the COMPAQ SMART and SMARTII controllers, which use
device names of the form /dev/ida/cXdXpX and /dev/cciss/cXdXpX.

Not sure if you are hitting the same...

No encapsulation

It's a new install, so to answer you're question : no

However it's not root disk encapsulation - It's a out of the book disk group I use for disk staging in Netbackup. I have other host with the same config, but this host is the only one that bring me into Linux maintenance mode. If I in maintenance mode run /etc/init.d/vxvm-boot the /dev/vx/dsk/dsudg/lvol1 device becomes available. Also if I comment out the vxvm volume in /etc/fstab and boot into normal mode, I can mount the volume by hand without problems.
