lvm problem

[JOHN TURNER_2]

We have a problem relating to lvm on a hp 11.00 system, someone has managed to create two logical volumes on the same physical extentents, We have tried to remove one of the logical volumes which has worked but it now won't let us remove the second logical volume that was sharing it's extents.

can anyone advise

What is error message?? How does lvdisplay and vgdisplay look like??

[Luk Vandenbussche]

If it is the only volume in the volumegroup you can remove it with vgexport

vgchange -a n /dev/vgxx
vgexport /dev/vgxx

[JOHN TURNER_2]

the error that i get when i try to remove the logical volume is:


sn9c:/var/tmp# lvremove -f /dev/vg00/servicenode
lvremove: Couldn't delete logical volume "/dev/vg00/servicenode":
The specified logical volume is open, or
a sparing operation is in progress.
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf

HI John,
Try doing:
# lvchnage -a n /dev/vg00/servicenode
# lvchnage -a y /dev/vg00/servicenode
# lvremove -f ...
See if that works.

when i try and lvchange the lvol, i get the following error msg

sn9c:/var/tmp# lvchange -a n /dev/vg00/debuglogs
lvchange: Logical volume "/dev/vg00/debuglogs" could not be changed:
The supplied lv number refers to a non-existent logical volume.


also when i lvdisplay the said volume group i get

LV Name /dev/vg00/debuglogs
LV Status available/syncd
LV Size (Mbytes) 0
Current LE 0
Allocated PE 0
Used PV 0

For this,

# lvchnage -a y /dev/vg00/debuglogs
# lvremove -f /dev/vg00/debuglogs

Hi John

1. lvremove should remove volume.

2. If there is only one volume in VG then vgexoprt can also be used

Hi John,

As of now your LV exists with Zero PE's. Only problem what you are having is that you are not able to remove the LV. It should be fine by creating another LV with some different name.

But apparently it apears as if your system is not patched properly. Are latest LVM patches applied ?

HTH,
