cur lv not equal to open lv, not mapping

[Matthew_50]

Though there's no any lv within /dev/vg01, but when i try to use`vgremove vg01`, the system replies as follows.

vgremove: Volume group "vg01" still contains a logical volume(s).
vgremove: Couldn't remove volume group "vg01".

when I use sam, -> Disk and File system -> volume groups -> vg01 ->
physical volumes=3, logical volume=1

but when i look into 'more information', there's no any logical volumes.

I also notice that the cur lv not equal to open lv, when I execute vgdisplay -v vg01.
result show as above.

don't have any clue to remove vg01, how should i do ?

[Stefan Farrelly · Accepted solution]

Just use vgexport instead of vgremove. This ignores any and all lvols and simlpy deletes the vg.

Did you check you /etc/lvmtab-file?

[Massimo Bianchi]

Hi,
what does

ll /dev/vg01/*

reports ?

Is there any other vg with the same minor ?

[Matthew_50]

here's the /etc/lvmtab info

/dev/vg01
>[B2
/dev/dsk/c0t2d0
/dev/dsk/c0t3d0
/dev/dsk/c2t2d0
/dev/dsk/c2t3d0

[Matthew_50]

when execute ll /dev/vg01

there's only a `group` file

crw-rw-rw- 1 root sys 64 0x010000 Jul 8 22:01 group

[T G Manikandan]

check whether you have defined any swap device on vg01.

[Matthew_50]

finally, it's removed.


cd /dev/vg01
mknod lvol1 b 64 0x010001
mknod rlvol1 c 64 0x010001

then, lvremove /dev/vg01/lvol1
now, the cur lv and open lv count are the same.
to release 'Alloc PE'

vgexport vg01
vgremove vg01
cp /etc/lvmtab /etc/lvmtab.old.2
vgscan -v

mkdir /vg01
mknod /dev/vg01 /group c 64 0x010000

pvcreate -f /dev/rdsk/c0t2d0
pvcreate -f /dev/rdsk/c2t2d0
pvcreate -f /dev/rdsk/c2t3d0

vgcreate /dev/vg01 /dev/dsk/c0t2d0 /dev/dsk/c2t2d0 /dev/dsk/c2t3d0

done.
