use fdisk -u to be sure the new, larger partition starts with the exact same sector as the old, smaller one. -- Ray Morris support@bettercgi.com Strongbox - The next generation in site security: http://www.bettercgi.com/strongbox/ Throttlebox - Intelligent Bandwidth Control http://www.bettercgi.com/throttlebox/ Strongbox / Throttlebox affiliate program: http://www.bettercgi.com/affiliates/user/register.php On 11/27/2010 09:58:18 PM, Yang Zhang wrote:
I was messing around with a VM running Ubuntu 10.04 Server (64-bit) with LVM on a single 4GB disk. I just used the installer's automatic LVM setup and I landed with (ignore the disk size - that was after I resized the disk to be 8GB): <<< Disk /dev/sda: 8589 MB, 8589934592 bytes 255 heads, 63 sectors/track, 1044 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0004b903 Device Boot Start End Blocks Id System /dev/sda1 * 1 32 248832 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 32 523 3942401 5 Extended Partition 2 does not end on cylinder boundary. /dev/sda5 32 523 3942400 8e Linux LVM >>> Ubuntu also made the LVM house just a root FS and a 512M swap. At this point, I grew the underlying disk to 8GB using the VM management software, then booted into the VM and tried to figure out how to grow my swap and root FS. Reading man pvresize: <<< ... EXAMPLES Expand the PV on /dev/sda1 after enlarging the partition with fdisk pvresize /dev/sda1 ... >>> This made me figure I had to first enlarge the partition with fdisk. So I tried deleting the extended partition 2 (which also deleted the logical partition 5 housing LVM), then recreating both partitions but this time using all cylinders (with the same partition numbers and also setting the logical partition's type to 8e for Linux LVM). Alas, that failed - I rebooted at that point, but the VM would no longer boot. (Sorry I didn't jot down the exact error message(s), but there was something about the /dev/mapper/testbox-root not being found - I can retry the whole experiment if this message is critical.) So is what I'm trying to do possible? What's the right way to go about it? Thanks in advance. _______________________________________________ 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/
