Hi,
Someone told me that we could just destroy the FileStore OSD’s and
recreate them as BlueStore, even though the cluster is partially
upgraded. So I guess I’ll just do that. (Unless someone here tells
me that that’s a terrible idea :))
I would agree, rebuilding seems a reasonable approach here. The SUSE
documentation [1] doesn't even allow Filestore OSDs before an upgrade
to a cephadm managed cluster. I don't have tried to upgrade Filestore
based clusters so I can't tell if this is related to Filestore in
general or a different issue. Anyway, moving towards Bluestore is
inevitable, so at some point you'll need to rebuild anyway. :-)
Regards,
Eugen

snap_mapper upgrade stuck
Hi,
I don't really have an answer, but there was a bug with snap mapper
[1], [2] is supposed to verify consistency, but Octopus is EOL so
you might need to upgrade directly to Pacific. That's what we did
on multiple clusters (N --> P) a few months back. I'm not sure if
it would just work if you already have a couple of Octopus
daemons, maybe you can try it on a test cluster.

Hi,
I’m seeing the same thing …
With debug logging enabled I see this:
2023-02-07T00:35:51.853+0100 7fdab9930e00 10
snap_mapper.convert_legacy converted 1410 keys
2023-02-07T00:35:51.853+0100 7fdab9930e00 10
snap_mapper.convert_legacy converted 1440 keys
2023-02-07T00:35:51.853+0100 7fdab9930e00 10
snap_mapper.convert_legacy converted 1470 keys
2023-02-07T00:35:51.853+0100 7fdab9930e00 10
snap_mapper.convert_legacy converted 1500 keys
It ends at 1500 keys. And nothing happens.
I’m now stuck with a cluster that has 4 OSD’s on Octopus, 10 on
Nautilus, and one down .. A hint on how to work around this is
welcome :)

Subject OSD upgrade problem nautilus->octopus -
snap_mapper upgrade stuck
Hi all,
I have problem upgrading nautilus to octopus on my OSD.
Upgrade mon and mgr was OK and first OSD stuck on
2023-01-12T09:25:54.122+0100 7f49ff3eae00 1 osd.0 126556 init
upgrade snap_mapper (first start as octopus)
and there were no activity after that for more than 48 hours. No
disk activity.
I restarted OSD many times and nothing changed.
It is old, filestore OSD based on XFS filesystem. Is upgrade to
snap mapper 2 reliable? What is OSD waiting for? Can I start OSD
without upgrade and get cluster healthy with old snap structure?
Or should I skip octopus upgrade and go to pacific directly
(some bug backport is missing?).
Thank you for help, I'm sending some logs below..
