Volume group "vg00" still has active LVs

[Karthikeyan.j]

vgrename fails on Rhel 4 AS gives a error active lvs exists .
tried booting in liux resuce but the lvm gets activated at boot ,same error occurs when we execute vgrename Volume1 Vol1

Volume group "vg01" still has active LVs

Note : /usr is mounted on lvol1 on vg00
/opt is mounted on lvol2 on vg00
/home is mounted on lvol3 on vg00
/var is mounted on lvol4 on vg00

What happens if you boot into single user mode, manually umount all the vg01 filesystems, and run 'vgchange -a n vg01'?

Why do u want to renmae LVs? Is that LV belongs to vg01 ot vg00?

if it vg01 , umount all file system from that VG and then do a vgchange -a n.

If it is from VG00.You may boot using rescue cd.make sure nothing is mounted from vg00 and Deactivate it.(as u said if it is already active).No normal file systems get mounted when you get shell prompt(#) in rescue mode.

Hi All
when i umount /usr , /opt/, /home ..etc i m not able to execute the commands vgchange so i had to copy the /usr to a normal file system and mount it and then when i execute vgchange -a n vg00 it says still lvs exists .

the reason why i want to rename is since our standards say we have to use vg00 but my mistake whe have created Vg00 i e the reason i have to vgrename it :)

Thx for all ur help :)

Hi Karthikeyan.j

The output of "pvs" and "lvs" may be helpful.
Do you have swap on any lvol?

Hi All
Pls find the output of Pvs and Lvs

PV /dev/cciss/c0d1p1 VG Vg01 lvm2 [67.81 GB / 48.81 GB free]

no swap is not on lvm partition

Hi

vg00 has 38G available space.
the 3 lvols in vg01 are together 19G.

Create three new lvols ( 15G 3G 1G ) in vg00.
mount them && copy data.

Then lvremove these vg01/lvols.
then vgremove vg01 ( vgchange -a n vg01 first)
then vgextend vg00 with /dev/cciss/c0d0p1

then you have your only vg00

Hi Hemmeter

The problem is on Vg01 application volumes are created /opt/psoft as 60 Gb /lvol1 vg01
and /opt/oracle 2gb lvol2 on vg01
/opt/tuxedo 2 gb lvol3 on vg01 .

[Hemmetter]

Hi

/opt/psoft 60 Gb lvol1 vg01
/opt/oracle 2 Gb lvol2 vg01
/opt/tuxedo 2 Gb lvol3 vg01

does not match your earlier posting:

PV /dev/cciss/c0d1p1 VG Vg01 lvm2 [67.81 GB / 48.81 GB free]
$ sudo /usr/sbin/lvscan
ACTIVE '/dev/Vg01/lvol1' [15.00 GB] inherit
ACTIVE '/dev/Vg01/lvol2' [3.00 GB] inherit
ACTIVE '/dev/Vg01/lvol3' [1.00 GB] inherit

These are quite different prerequisites.
So you have to backup your data somewhere else before moving c0d1p1 to vg00.
