can not remove logical volume

[Marco Varenkamp]

Hi all,
I can not remove a logical volume via sam.
the lv is defined as unsused.

the error message is:
The supplied lv number refers to a non-existent logical volume.

vgdisplay looks like that:
--- Volume groups ---
VG Name /dev/vg01
VG Write Access read/write
VG Status available
Max LV 255
Cur LV 0
Open LV 1
Max PV 16
Cur PV 1
Act PV 1
Max PE per PV 8811
VGDA 2
PE Size (Mbytes) 4
Total PE 8809
Alloc PE 0
Free PE 8809
Total PVG 0
Total Spare PVs 0
Total Spare PVs in use 0

The lvdisplay looks like that:
--- Logical volumes ---
LV Name /dev/vg01/lv01
VG Name /dev/vg01
LV Permission read/write
LV Status available/syncd
Mirror copies 0
Consistency Recovery MWC
Schedule parallel
LV Size (Mbytes) 0
Current LE 0
Allocated PE 0
Stripes 0
Stripe Size (Kbytes) 0
Bad block on
Allocation non-strict
IO Timeout (Seconds) default

can somebody give me a hit, how to remove the lv?
thanks in advance
Marco

Hi,
If the logical volume is mounted, first umount the filesystem (and remove the entry from /etc/fstab ... if there is one) :
#umount /filesystem
Then remove the logical volume
#lvremove /dev/vg01/lv01

This is destructive !!!

Hope this helps,

Hi,

You can try:

lvremove -f /dev/vg01/lv01

but if that also returns a similar error then the logical volume doesn't actually exist in the volume group - it's zero size anyway. In that case then you can safely remove the device files:-

rm /dev/vg01/lv01
rm /dev/vg01/rlv01

Regards,
John

With the output of vgdisplay, I'm able to notice that vg00 has only one logical volume named lv01.
My suggestion is to export vg01 and create a volume group again.

# vgchange -a n vg01
# vgexport /dev/vg01

Hope this helps,
