Problems with deleting logical volumes
Artur Uszynski
I have problems with one of volume groups. When I delete a filesystem
from it, I receive the message, that logical volume (which was used by
this filesystem, for instance lva01) cannot be deleted. However, this
logical volume IS deleted (lspv and other commands doesn't show it
anymore), but in /dev directory file named as this LV (lva01) exists.
When I want to create LV with the same name (lva01), there appears a
message saying, that the name is in use. So, in /dev I have some
files, which I can't delete (rmdev does not work, I dont think rm is a
good idea). I don't know, if they are affecting the system. Below
there is fragment of smit.log, which shows all actions leading to
described situation. Is there any solution ?
The problems started after I reinstalled the system from image backup.
Volume groups other than rootvg where NOT automaticaly recreated, I
had to do it manually, and then everything started.
Please help if You can.
Thanks.

Looks as though you've got some hangover references to this lv name in
the ODM, are you 100% sure it's gone, Use lspv -l hdisk3 and lsvg -l
VGName
If it's really gone, use odm commands such as odmget & odmdelet to
remove refs from the odm
Syntax is something like
odmget CuAt | grep -p lvname
then use odmdelet to remove these rouge instances.
odmdelete -o CuAt -q name="lvname"
These are Aix 4.1.5 commands, older Aix's use odme. Be very careful
with ODM.
Good Luck
