vg removed ... files still there

[Omar Alvi_1]

Hi,

I have a volume group which I removed using SAM. However the configuration files still exist. I mean /dev/vg#.

Can I simply manually remove these files?

Regards

LVM should not let you remove the volume group without destroying all logical volumes. Which would get the files.

Seems you had a few goodies hidden in the mount folder. Depending on what fs we're talking about its probably okay to rm the files.

Would be careful with /etc /usr /var things like that.

Hi

Have a look at

/var/sam/log/samlog

When you remove a volume group with sam, it will unmount the logical volume, remove it then vgremove the volume group. Following that it will remove the group file within dir /dev/vg# and then the corresponding directory

Your answer is yes, as this is what sam actually does

Hi Alvi,

If you are sure that your VG is not there anymore (by doing vgdisplay vgxx and 'strings /etc/lvmtab') then you can safely remove these files. I would suggest teh following steps to confirm the non-existence of the VG by

#vgchange -a y vgxx

You should get "
volume group does not exist" etc.,

If it is successful or gives some other error than the above, then your vgremove operation was not successful through SAM. IN this case, find all the logical volumes that are active and unmount them. If you are using raw devices, make sure they are not accessed by using "fuser -cu /dev/vgxx/rlvol*" command. Once it is done, then you can manually remove the vg by using 'vgremove vgxx' command.

Hi,
verify the status of vg
vgdisplay -v vgxx (
---
if you make a
vgexport vgxx
you delete the vg config.

Maybe you have in your dir /dev/vg00 "group" the node.
You should remove it, if you don't you use anymore the vg
rm -rf /dev/vgxx
