I renamed my volume with vgrename however I didn't complete the other steps. Mainly update fstab and intiramfs. Once I booted, I was dropped on the Dracut shell. From here I can see the newly rename VG and I can lvm lvscan as well as activate it, lvm vgchange -ay. However I can't figure out what to do next, I'm assuming I need to regenerate the initramfs and then boot to change grub? Could someone point me in the right direction to recovering a FS from Dracut, or other means, once the volume group name w...

Hi, I am trying to recover data from my old system which had LVM. The disk had two partitions - /dev/sda1 (boot, Linux) and /dev/sda2 (Linux LVM). I had taken a backup of both partitions using dd. Now I am booting of CentOS live cd for system restore. I recreated partitions like previous system using fdisk and then used dd to dump all the data onto it. I would like to mount sda2 as LVM, but I

Hi all I want to shrink one of my LVM based domU''s, but don''t quite know how to do it. I have searched the Wiki & HOWTO''s, and they all show you how expand / enlarge a LVM based domU, but not shrinking it. So, I stopped (destroyed) the domU, and then resized it as follows: lvresize /dev/data/cpanel1 -L10GB (It was 100GB), but when I a started it up again, I

Hi all- I''m hoping someone can help me with this problem with Xen under CentOS 5.1 (RHEL 5.1) I''m having... This is the Xen package that comes stock with the distribution, I didn''t compile it from source. I can boot Domain0 and the hypervisor just fine. I''m trying to bring up a Xen guest VM and it crashes on boot, with this error: # xm create -c tcga1

...0 SHV Server Board. 2) Installed Centos 5.1, default LVM style. Anaconda saw a single 500GB disk so I assumed this was a true hardware RAID system. Am I wrong here? 3) Then wanted to reduce LogVol00 so as to make room for a new, data only filesystem on its own LV. Started by booting with rescue CD, lvscanned the disk, lvchanged -a y. Intended to resize root filesystem with resize2fs. Was asked to fsck, which I did (by the way, getting many errors). Fixed them all (fingers crossed), fsck again said ok. Then resize2fs worked happily. 4) Rebooted the installed system. Now "Duplicate PV" shows...

Can anybody tell me if it makes a difference if domU''s have separate LVM volume groups? For instance, the Xen User Manual ( http://tx.downloads.xensource.com/downloads/docs/user/#SECTION03330000000000000000) says, when setting up a domU''s disks with LVM, to do a vgcreate vg /dev/sda10 Should each domU have it''s own volume group, or can all the domU''s share

hello everyone. i guess this has been asked before, but haven't found it in the faq. i have the following issue... it is not uncommon nowadays to have desktops with filesystems in the order of 500gb/1tb. now, my kubuntu (but other distros do the same) forces a fsck on ext3 every so often, no matter what. in the past it wasn't a big issue. but with sizes increasing so much, users are
