Removing logical volume has not freed up disk space on the volume group

Hi,

 

I have removed a logical volume from a volume group via SAM but because our /tmp area was full (and SAM needs a bit of space on /tmp to be able to delete a logical volume) it has only removed the entry from fstab and not freed up the disk space on the volume group. I have since manually removed the entries from /dev/"volume-group-name".  I restored the entries and then run an lvremove but it came back with the following (the logical volume concerned is lvCAST and the volume group concerned is vgEVA):

/dev/vgEVA

I have also a run a vgscan to no avail. Is there anything else I can do other than ultimately removing the logical volumes and volume group and recreating it all (taking a backup first of all of course!).

 

Kind Regards - Mark P.

Re: Removing logical volume has not freed up disk space on the volume group

Does a 'vgdisplay -v vgEVA' still show that LV as part of the VG?  Can you do an 'lvdisplay /dev/vgEVA/lvCAST'?

Re: Removing logical volume has not freed up disk space on the volume group

Please post a full "vgdisplay -v vgEVA" first.

Hope this helps!
