Hi achenle,
I'm in complete agreement with you, the RAID-5 is at the hardware level. However my keen eager beaver colleageus have requested that I rebuild the server using LVM, having waited until the delivery build was complete and in alignment with the original specification provided.
I tarred up the full system last night and will reinstall the system this morning and restore over the new LVM based install. That is if my colleages ever get back to me with the required volume groups.
Anyway, thank you for your input.
Regards
Dave

vgcfgbackup
VGCFGBACKUP(8) System Manager's Manual VGCFGBACKUP(8)
NAME
vgcfgbackup - backup volume group descriptor area
SYNOPSIS
vgcfgbackup [-d|--debug] [-h|--help] [-v|--verbose] [VolumeGroupName...]
DESCRIPTION
vgcfgbackup allows you to backup the metadata or Volume Group Descriptor Area (VGDA) of one to all volume groups to files in /etc/lvmconf.
If you don't give any volume groups in the command line, all of them will be backed up. This DOESN'T backup user/system data in logical
volume(s)! To restore volume group descriptor area backups see the vgcfgrestore(8) tool. A 10 step history is backed up in /etc/lvm-
conf/VolumeGroupName.conf and /etc/lvmconf/VolumeGroupName.conf.[1-9].old. This enables you to restore your volume group configuration up
to 10 steps back in the backup history.
OPTIONS
-d, --debug
Enables additional debugging output (if compiled with DEBUG).
-h, --help
Print a usage message on standard output and exit successfully.
-v, --verbose
Gives verbose runtime information about vgcfgbackup's activities.
DIAGNOSTICS
vgcfgbackup returns an exit code of 0 for success and > 0 for error:
1 error doing backup
95 driver/module not in kernel
96 invalid I/O protocol version
97 error locking logical volume manager
98 invalid lvmtab (run vgscan(8))
99 invalid command line
