Does LVM support extending LUN size?
LVM1 does not support extending lun size.
I extended size of an existing LUN from my disk-array manager but vgdisplay shows me always the original size (with no free physical extents). No change if I reboot, I need to destroy and re-create volume group.
did you partition the lun or are you using a whole device?
in the former case you can add a second partition, in the latter your
only chance is to reduce the lun again and assign the space as a new
lun, iirc you should be able to allocate more than one lun from the same disk group. i
am not that sure about reducing.
Watch out for the maximum number of sd devices in the kernel which is probably limited to 40 (CONFIG_SD_EXTRA_DEVS)
