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) L. -- Luca Berra -- bluca@comedia.it Communication Media & Services S.r.l. /"\ \ / ASCII RIBBON CAMPAIGN X AGAINST HTML MAIL / \
