I have a laptop that I put centos 7 on and I started out with a 30gig partition.? I resized the other part of the disk to allow more space for centos.? I then created an unformated partition in the available space,? ran pvcreate /dev/sda4 vgextend lvname /dev/sda4 lvextend -L 184.46G /dev/lvname/root but when I run: sudo resize2fs /dev/lvname/root I get: resize2fs: Bad magic number in super-block while trying to open /dev/lvname/root Couldn't find valid filesystem superblock. How do I resize the volume? Thanks, -wes

This patch is easier to read if you use the 'git show -w' option. Also observe that: fun a -> ( fun () -> (* code *) ) (ie. returning a closure) is identical to: fun a () -> (* code *) Rich.

...lder, and then migrated those from their .qcow files to lvm.

I have a series of unmounted lv's that are used in xen vm's of various flavors in a lab environment. I made a script that I use to backup all of them prior to doing anything I may need to undo and all I execute is: dd if=/dev/vgname/lvname of=/dir/name.img Are there any additional parameters I should use? I haven't tried to restore this into an lv, but I did swap the 'phy' specification for 'file' and started a vm using the backed up image and it was fine. Thanks! jlc

Just discovered that on CentOS 4.1 when you issue the command: lvcreate -s -n temp -L2G /dev/vgname/lvname to create a snapshot, you get the error message: snapshot: Required device-mapper target(s) not detected in your kernel I've checked and recheck my spelling and tried using the device created under /dev/mapper. I've tried it on both x86_64 and on i386. Works as expected under CentOS 3.5...

The way I''ve done it in the past is: 1. Make sure that xen domain is shut down that you are re-sizing 2. Run lvextend (you''ve already done this) 3. Run e2fsck -f [logical volume name] (i.e. /dev/domain0/lvname) 4. Run resize2fs [volume name] [new size in G of LV] (i.e. resize2fs /dev/domain0/lvname 8G 5. Start up vm. New size should be reflected now. HTH -----Original Message----- From: xen-users-bounces@lists.xensource.com [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of John S Little Se...

Hi, I have a centos 4 box i use for a file server (nfs and samba). It has two hdd: hda is for the standard install; hdb is for /export/samba/netdisk0 hda is lost - it just clicks now i think hdb is still good i can't figure out how i can remount the hdb disk in a new machine and retrieve the info from it; i've scanned the LVM howto and googled some LVM topics, but nothing seems to

...ks like you want to skip the pvmove. That's fine, but it means more downtime (an unreliable estimate is one minuted per GB). In that case, you don't even need the snapshot. You won't need a point in time copy if you are copying from a stable source. > 1. Shutdown domU source (source lvname = win2k8-source) which is never > file mounted in Xen dom0, just "lvm'd". Yeah, just turning off the guest and making sure it doesn't have the ``o'' flag set in the ``lvs'' output is enough. I hope that nothing else had it open (for writing) while your guest wa...

I'm running CentOS 5.2, it uses LVM to manage the disks and we had a programmer do something (not sure what) then reboot the system. When it came up it kernel panicked. Luckily it's not production, it was their sandbox. But they didn't backup any of their files. I know the disks are fine because I was able to boot from a linux live cd and mount the /boot partition from the sda
