If that's the case you may have to reboot or reload the controller driver, both of those of course would be outages. Here's what you can do to determine what the kernel believes the size of the device is you can issue blockdev --getsize /dev/sda and that will return the size of the device in 512 byte blocks, or to get it in KiB you can simply use this bash statement: echo "$(($(blockdev --getsize /dev/sda) >> 1))" -- Zac Slade krakrjak@volumehost.net ICQ:1415282 YM:krakrjak AIM:ttyp99 _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
