Something I have been thinking about, but not sure whether I can do it.
I have a bunch of data on a 300GB drive, in a 250GB LVM volume. This
drive is in an external USB box. I would like to migrate the data to
a different LVM volume on an internal 500GB drive. Obviously this can
be done using tar piped to tar, or rsync, or other means. Possibly by
using LVM commands that I don't quite understand.
Maybe this is the section "Removing an Old Disk" in the LVM HOWTO.
Could it be done by setting up a mirrored pair between the two drives?
Then at some later time I could break the mirror and unplug the
external drive and put it somewhere for safekeeping.
Another future time I could get another external drive and again set
it up as the second drive in a mirror pair. Repeat, storing old disk
drives somewhere until it is time to reuse them.
Given that I don't quite know what I am talking about here, ideas or
command-line recipes are welcome.
As a side comment, I wish that whoever writes the LVM HOWTO would
arrange to print the revision number on every page of the
documentation. I have three copies of the document, different
revision numbers, and the section numbers wander all over the place.
Suppose I should just throw out the old ones. :-)
