Hi all,
I'm storing LVM information in a postgres database, and wanted to use
the UUID from the PVs / VGs / LVs as the UUIDs in the database. I
noticed when I tried to do this that postgres complained that the UUID
was not valid. I checked with an online UUID validator
(https://www.freecodeformat.com/validate-uuid-guid.php) and it also
reported as invalid.
Example;
====
# pvdisplay | grep UUID
PV UUID jLkli2-dEXx-5Y8n-pYlw-nCcy-9dFL-3B6jU3
====
Is this a known issue?
Hi
At the time of lvm2 devel I believe UUID was just a unique identifier,
later some effort to standardize it came in.
But really you should NOT be using basically internal unique identifiers
in your DB - this are internal to DM/LVM work and might be changed at any time
to something else.
User is supposed to use 'vgname' & 'lvname' - so there you can put those
valid UUID sequences - although human readable strings are always nicer ;)
