if the lv is the only thing sitting onto a set of pv
you can just:
lvchange -a n on the old host
move the disks
avtivate the vg with the --partial option on the new host
then run vgreduce --removemissing on both machines.
On server1 and server2 we have a hdc1 which is a Linux LVM, i have
created a vg called "testvg", and then a number of lvs "testlv1" to
"testlv5" on server1 and now want to move "testlv3" (for example)
over to server2.
then you have two different disks one in each server.
in this case you have to create a suitable vg and lv on server2
either copy the data from a mounted filesystem
or you dd the whole lv.
(Sorry, a bit new to this and might not have the terms down yet)...
If i to a "vchange -a n /dev/testvg/testlv3", which makes it now
unavailable within the vg... when you say "move the disk" do you mean
pysically move the disk?
ignore my previous mail, it does not apply to your case.
Again, sorry - i didnt explain myself enough in the first place.
Apprciate any help here!
