[linux-lvm] lvchange problem



Hi all

I have come across a problem with lvchange.  When I change the availability
of an LV from active to inactive, and then try and change it back I get the
error "Operation not permitted".  I can only get the LV back by rebooting.

A search of Google turned up something similar but there were no responses
to that post.

System details are: 
Pentium II-400
2 x 20GB Quantum drives
256MB RAM
2.4.14 with XFS
lvm-tools              1.0.1rc4-2
Gnu C                  2.96
Gnu make               3.79.1
binutils               2.11.90.0.8
util-linux             2.11f
mount                  2.11g
modutils               2.4.6
e2fsprogs              1.23
reiserfsprogs          3.x.0j
Linux C Library        2.2.4
Dynamic linker (ldd)   2.2.4
Procps                 2.0.7
Net-tools              1.60
Console-tools          0.3.3
Sh-utils               2.0.11


Any ideas?
