problem with a logical volume

[Alan Casey]

I recently restored my rootvg from ignite tape, and in the process didn't restore one of the logical volumes, called monitor.
When I try and run make_recovery -A I get:

save_config: error - cannot determine lv "/dev/vg00/monitor" usage via fstyp

And if I try and remove the UNUSED logical volume I get:

image1(root)/opt/ignite/bin> lvremove /dev/vg00/monitor
lvremove: Couldn't delete logical volume "/dev/vg00/monitor":
The supplied lv number refers to a non-existent logical volume.
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.con
f

Anyone know what I need to do to get rid of this lvol?

Hi Alan,

Does a lvreduce -f -k do the job?

Alan,

Check with "strings /etc/lvmtab" to see if this lvol is still in your lvmtab. If it is, make a new lvmtab:

mv /etc/lvmtab /etc/lvmtab.bak
vgscan -a

Hi,

Check /etc/lvmconf/vg00.conf and see wheather monitor logical volume is there ?
please check /dev/vg00/ for device file of monitor logical voulme.

post the o/p of
#ll /dev/vg00

first remove the device files of that lvol present in the /dev/vg00 VG.

That should take care,

vgscan or lvreduce didn't work.

image1(root)/dev/vg00> ls -l *monitor*
brw-r----- 1 root sys 64 0x000010 Oct 29 11:12 monitor
crw-r----- 1 root sys 64 0x000010 Oct 29 11:12 rmonitor

Note: make_recovery is obsolete, use make_tape_recovery

You might even get a better error message.

If /etc/lvmtab is valid, the script I'm attaching should tell you which physical volume is giving you trouble.

Ignite is now a pretty good tool for finding missing disks because it won't work when one is messed up or turned off.

You may need to deactivate the volume groupo, vgexport the volume group and import it back in.

Then activate it and see if the problem is fixed. Any issues that come up during this process will help you identify and correct the actual problem.
