i've a RAID device, with a VolumeGroup & a LovicalVolume,
/dev/md3 -> VG('VG01'):LV('test'):'/home/test'
i've added a new LV to VGO1's available space,
lvcreate -n new_DomU -L 4G /dev/VG01
dd if=.../template of=/dev/VG01/new_DomU
i need to *exclude* '/dev/VG01/new_DomU' from lvm scanning, but make
sure the 'home/test/ mount is still scanned.
in lvm.conf, if i set,
filter =[ "a|/dev/md[3]|", "r|.*|" ]
it correctly excludes the entire block-dev, and it's VG/LV contents.
but, @ attempt to, e.g.,
dd if=.../template of=/dev/VG01/new_DomU
then returns,
Volume group "VG01" not found
iiuc, the 'filter=' specification filters on block-devices only, not
VG/LV names (at least i've not figured out a regex that works, yet).
is there any way to exclude just certain LVM's in/on a block device,
leaving the rest scannable?
thanks.
