Usual way if something goes wrong:
Check if there is a device in 'suspend' state -
(i.e. dmsetup info -c and check for 's' flag in Stat column)
Resume all suspend devices - dmsetup resume vgname-lvname &
You could easily remove those which have zero open count - dmsetup remove
Eventually if you are brave enough, you could try 'dmsetup remove_all'.
Now you should be able to activate your LVs again.
Obviously 5.8 is somewhat older and there are some old bugs likely already
fixed in newer releases - thus you may have far less problems with newer RHEL?
(or use support for reproducible bugs?)
