Removing a LV with lvremove

[Jonathan Caplette_1]

Hi guys,

I tried to remove some LV's from my vg01, I got this error for each lv:

[jcaplett@morpheus]$ sudo /usr/sbin/lvremove -f /dev/vg01/lvl89rw1
Current path "/dev/dsk/c24t0d0" is an alternate link, skip.
Current path "/dev/dsk/c26t0d3" is an alternate link, skip.
lvremove: Couldn't delete logical volume "/dev/vg01/lvl89rw1":
The specified logical volume is open, or
a sparing operation is in progress.
Volume Group configuration for /dev/vg01 has been saved in /etc/lvmconf/vg01.conf

I check they're not mount on a FS, they have no open file or process using these LV's, they're all part of a PV, and I have some data on my vg01 that I don't wanna lose!!

Own can I remove my LV's???

Looks like a patching issue . are you uptodate on LVM patches . LVM is pretty stable unless there is some patch issues .

If this is HPUX11.0 try this patch PHKL_30553 or superceeded .

if your vg01 contained one or more physical volumes from a disk array of some sort which was configured with a hot spare, and this logical volume has a hook to this hot spare, this may cause you the headache.

vgdisplay -v vg01
lvdisplay /dev/vg01/lvl89rw1
pvdisplay -v (all volumes in vg01 here one by one until the line :
--- Physical extents ---
encountered)

if you can post this info, it can be a great help understanding your disk topology.

Hi Jonathan,

Try issuing the command "umount /dev/vg01/lvol90rw1" and see. Also recreate /etc/mnttab by

#mv /etc/mnttab /etc/mnttab.sav
#bdf
#umount /dev/vg01/lvol90rw1

If that doesn't work, try

#fuser /dev/vg01/lvol90rw1
#fuser /dev/vg01/rlvol90rw1

And see if they are being opened. You can also try "lsof" and see if this logical volume is in use.

do following which might help

fuser -ck /file_sys_name
then do lvremove on those Lvs.

Hi ,

Try using lsof ,

you will see which file is open by who ...

Bye.

Probably because they are still mounted or open? You need to unmount your logical volumes before you can remove them. Do a bdf or df to check if they are mounted or not. If they are mounted, do a
ps -ef | grep
to see if there's anything runs on it. If they are not mounted, check if the logical volume is used for mirror or not.

Thanks for the help!! I double check what it was, I found that was a application using raw device!! :S

Sorry!! but thanks for the answer!!

I am having the same open error when trying to remove a raw logical volume.

How did you get the logical volume to delete?
