Operating Systems Linux SuSE Remove disks from VGs in LVM Post 302301344 by mark54g on Thursday 26th of March 2009 03:21:01 PM

I would recommend that you add a drive sizable to contain the filesystems to your volume group, then pvmove to them, and then vgreduce the drives out of your VG and then power off, remove the disks and be done with it


If you don't want to remove them physically, and want to keep them for something else, you can fdisk them and use them for whatever.

run lsscsi to show the drives in a more readable way

NAME
vgreduce - reduce a volume group SYNOPSIS
vgreduce [-a|--all] [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [--removemissing] [-t|--test] [-v|--verbose] VolumeGroupName [Physi- calVolumePath...] DESCRIPTION
vgreduce allows you to remove one or more unused physical volumes from a volume group. OPTIONS
See lvm for common options. -a, --all Removes all empty physical volumes if none are given on command line. --removemissing Removes all missing physical volumes from the volume group, if there are no logical volumes allocated on those. This resumes normal operation of the volume group (new logical volumes may again be created, changed and so on). If this is not possible (there are logical volumes referencing the missing physical volumes) and you cannot or do not want to remove them manually, you can run this option with --force to have vgreduce remove any partial LVs. Any logical volumes and dependent snapshots that were partly on the missing disks get removed completely. This includes those parts that lie on disks that are still present. If your logical volumes spanned several disks including the ones that are lost, you might want to try to salvage data first by acti- vating your logical volumes with --partial as described in lvm (8).
