How about if I remove it from the file /etc/filesystems the entry for /space ? and then try it or do it need to reboot the machine ?

Send me the output of
Code:
sysdumpdev -l
lsps -a
Also, try
rmfs  /space

By the way when you run rmlv, you just mention the lvname and NO /dev
So, it should be
rmlv -f fslv00

Ok,
Have you tried varyoffvg patchtest?

If that doesn't varyoff, then you have to look into each vhost and their backing device and compare it with lsvg -l `lsvg` output.

If you see some devices from patchtest VG remove them.
