So currently I think it happens on snapshot

initial assumption what could cause the interruption. Ok, then another suspect
could be the rbd_support mgr module.
On the other hand, they have large number of purged_snap keys on both
the primary
and the secondary clusters. If it had been due the rbd_support mgr
module I would
have expected to see it on the primary cluster only (they do not do
"two way" mirroring
as far as I know).
Hi Mykola,
Yeah, rbd_support module is just a fancy way of calling "rbd mirror
image snapshot" command (rbd_mirror_image_create_snapshot API). There
is nothing in the Python code itself that deals with snap IDs.
Answering your other question: recovering from blocklisting in
rbd_support module is very recent and hasn't been backported even to
pacific [1], let alone octopus which went EOL a year ago.
