Hi, David!
In case of dm-crypt luks (as default) ceph-disk keeps particular OSD
partition\partitions key in ceph mon attributes and uses OSD partition uuid
as an ID for this key.
So you can get all your keys running:
/usr/bin/ceph config-key ls
You'll get something like:
[
...
"dm-crypt/osd/50250ade-500a-44c4-8a47-00224d76594a/luks",
"dm-crypt/osd/940b5b1c-5926-4aa5-8cd7-ce2f22371d6a/luks",
"dm-crypt/osd/dd28c6ba-c101-4874-bc1c-401b34cb2f9b/luks",
...
]
These uuids are partition uuids.
You can get particular key as:
/usr/bin/ceph config-key get dm-crypt/osd/<OSD_PARTITION_UUID>/luks
As I don't use external wal\db partition currently I can't tell the exact
config path for their keys, but I believe a scheme will be the same.
Best regards,
Vladimir
