unable to remove LV

[jeevarajkn]

Dear Guru's

model-RX6600
OS-11.23

Iam try to remove two lv’s ie; /vg00/lvol11 and /vg00/lvol12 but getting error says that this lv’s already mounted and cannot be removed but this lv’s not showing in bdf ouput,/etc/fstab/,/etc/mnttab also.

Error:-

UAEMFQDDCBDBD01:/tmp>lvremove /dev/vg00/lvol12

The logical volume "/dev/vg00/lvol12" is not empty;

do you really want to delete the logical volume (y/n) : y

lvremove: Couldn't delete logical volume "/dev/vg00/lvol12":

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





UAEMFQDDCBDBD01:/tmp>mount -F vxfs /dev/vg00/lvol12 /jee

vxfs mount: /dev/vg00/lvol12 is already mounted, /jee is busy, allowable number of mount points exceeded
.



Plesae help me solve this issue.

umount the file system first.

Hi,

Do you know the mount-point of /dev/vg00/lvol12?

Try remove and recreate the mount-point (directory). Let me know the result.

Thanks,

Hi Jeev,

Try doing this:
# mv /etc/mnttab /etc/mnttab_bak <== move mnttab
# mount -a <== recreate mnttab

If you know the mount points of these lvols; try :
# fuser -c <== to see the use of these mount points
If you find any process in this, you can try killing them.

Regds,
R.K.

Hello,
if its not showing in bdf output and in /etc/fstab then it may use somewhere in background.

is it possible to reboot this system once? if yes proceed for it.

another way you can kill by finding fuser

hi,

1. is it still mounted ? check first!
2. if not mounted, is it share disk?
3. if not, try to fuser -cu or use lsof to define what process still use this lv

Dear Friend

Remove a logical volume without requiring user confirmation:
lvremove -f /dev/vg00/lvol2 but should careful this command destroys all data in the specified logical volumes.

thanks and regards

hi,

lvol12 and backup using the same PE = LVOLs are identical,

"if you are know what you are doing",

umount backup / backup1 / lvol11 / lvol12,

them lvremove of them and recreate a new LV-s.

and create a new FS and mount it as some mountpoints.
