linstor-proxmox v7.0.0-rc.1

Dear DRBD on PVE users,

This is RC1 of the upcoming 7.0.0 release of linstor-proxmox. First
things first: This *requires* LINSTOR 1.21.1 (or newer).

So far we more or less (size reporting was always a mess) tried to show
a node-local view of storage. For example we only showed pools that
actually exist on a node. This was okay, but had two problems:

- showing only the local storage in a distributed cluster does not make
too much sense. The actual data lands on nodes LINSTOR decides.
- there are people that have the storage nodes pretty much separated
from the PVE nodes. For these we did not show any storage information
on such nodes (as they did not have the RG's SP deployed), which is
rather confusing.

Now we shifted the calculation of free/used storage to LINSTOR and that
is what we show on all nodes.

tl;tr: we shifted from a node local view to a cluster view.

For PVE nodes we have the following assumption, which we already had:
- linstor-satellite (and all that comes with it: drbd-utils,
drbd-dkms,...)
- linstor-proxmox plugin installed

If nobody complains this will become 7.0.0 in about a week from now,
please test.

If you use PVE7, you can take this package for testing (LINSTOR should
already be in the stable repos):

Hi Roland,

Showing cluster wide storage usage/calculation is great. However on my
test cluster used/free space in Datacenter->Summary is ... well -
strange. Shows very different values than under node view and the values
sometimes change after a few seconds. Even when they stabilize they are
wrong either used is low and free is correct or vice versa. Very
strange. In node view all is fine. I have PVE and Linstor updated to the
latest.

Best regards,
ds

Hi Roland,

You can disregard this report. After playing a bit more with PVE GUI I
noticed that the graph on one of the nodes doesn't correspond to the
values in the status. After restarting pvestatd on all nodes everything
is working just fine. Sorry for false alarm. Keep on the good work.

Best regards,
ds
