I am running CentOS 5.6 on a VPS.Using yum can I remove the lvm2 package from my vps without causing issues with the filesystem for reads/writes? Is the actual disk managed by the host ... [by Light_Speed]
I'm trying to make an emergency recovery disk with Mondorescue to:
Restore my server in case of hardware (or severe software) failure.
Make an "identical" server setup for debugging and staging. My original image was lost when my laptop died, during setting up this server. Then I had to do it again from scratch in a hurry..
As for LVM2 and snapshot file consistency, I'm assuming that ext4 has freeze_bdev() implemented in it? And if so, can it be said that this implementation will guarantee a freeze of a filesystem and lock it for a consistent state for a lvm2 snapshot? And if not, would ZFS be better?
I have a Fedora 11 system that runs mythtv and stores the recorded video on an LVM drive. I use xfs because it was suggested by the howto that I followed when I originally installed. I want to replace a 200G drive with a new 1T drive.
Well, upon further investigation it relates to the LVM partitions. With lvm2 and device-mapper 2.02.100-1 the system boots reliably without the lvm2 HOOK, but from 2.02.103-1 it requires the lvm2 HOOK.If I upgrade to the latest packages, add the lvm2 HOOK, rebuild the initramfs and reboot the system comes up successfully.
