logical volume "NOT available" after reboot - iSCSI LUN

[rib]

Hello everyone,

I have installed centos 5.7 and connected it over 2 NICs to a iSCSI storage (2 pathes):

- iSCSI (SW initiator) and multipath config done
- disk device (LUN): dm-5
- created a partition: dm-5p1
- created pv: /dev/mapper/dm-5p1
- created vg: vgxx
- created lvol: lvolx
- filesystem ext4
- fstab: /dev/vgxx/lvolx /mountpoint

It's working so far, but after reboot, the logical volume lvolx is "NOT available" (vgdisplay -v).
When I run "lvchange -a y /dev/vgxx/lvolx" I can mount the filesystem again.

How can I fix this, so the lvol and fs automatically starts at boot?

Thx and best regards

Now I found the following site: asianux.com/node/212
"After setting up a LVM on the iSCSI device, it works fine. But after a system reboot, the LVM is not automatically activated."
Can this be used on CentOS5, too?

Sound promising, same issue on my CentOS Server.
