LVM diskgroup not listet in /dev


we are using a VMWare guest SLES11.3 x86_64 and try to use LVM with ext3 as a datastore.

The problem is that the LVM VolGroup do not show up in /dev

We can see the vm devices in fdisk and created a volgroup to add the disks.

But the VolGoup will not be mapped to /dev/ORAPOOL but we do not understand why

lboptb01:/dev # pvs

/dev/sdc1 ORAPOOL lvm2 a-- 20.00g 0

Thanks for advice

Did you try “vgchange -ay ORAPOOL”?


thank´s that solve my problem but why I do have to activate the pool by hand or script after every reboot ?

Does LVM or DM can do it on reboot ?
