Operating Systems AIX AIX 5.2 performance question Post 302254656 by jhall on Wednesday 5th of November 2008 12:04:15 AM

Thank you for your replies. The system is only this busy during the nightly processing. Otherwise, it is mostly idle.

I do know that the volume group, logical volume, and filesystem configuration is far from ideal. The entire system is running from local disks. Some of the application filesystems are located in the rootvg. I am just trying to figure out the best course of action to fix these issues.

I will capture the output of the commands above during tomorrow's processing and post the results.

Thanks again!

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).
