Logical Volume Management on Linux

NOTE: remember to add snapshot support when calling lvcreate

FAQ

Access logical volumes within logical volume

partprobe /dev/mapper/vg-mydata
lsblk

This will show the (sub) partitions/volumes, then edit /etc/lvm/lvm.conf

filter = [ "a|.*/|", "a|mydata|","r|.*|" ]

Then run:

vgscan
lvscan
vgs

Now you should see the names of the volumes you're looking for, so now:

vgchange -a y guestsname_mydata-home

and then you should be able to

mount /dev/mapper/guestsname_mydata-home

When done, remember to change back the filter in lvm.conf, default is

filter = [ "a|.*/|" ]

and of course then once again

vgscan
lvscan
