Hi I've recently rebuilt my home server using centos 7, and transplanted over the main storage disks It's a 3 disk raid5, with an lvm storage group (vg03) on there Activating and mounting works fine: # vgscan Reading volume groups from cache. Found volume group "vg03" using metadata type lvm2 # vgchange -ay 1 logical volume(s) in volume group "vg03" now active # lvscan ACTIVE '/dev/vg03/storage' [<1.82 TiB] inherit I can then mount /dev/vg03/storage as expected However on a reboot, boot fails if I add that entry to fstab: 'Timed out waiting for device dev-mapper-vg03\x2dstorage.device' I then have to activate it again with vgchange. I'm guessing I'm going to need a grub option, or do something with dracut but I'm a bit stuck here Thanks Duncan
