While the MDS cluster is unstable and changing state the client may get mdsmap updates that will trigger warnings:
[144692.478400] ceph: mdsmap_decode got incorrect state(up:standby-replay) [144697.489552] ceph: mdsmap_decode got incorrect state(up:standby-replay) [144697.489580] ceph: mdsmap_decode got incorrect state(up:standby-replay) This patch downgrades these warnings to debug, as they may flood the logs if the cluster is unstable for a while. Signed-off-by: Luis Henriques <lhenriq...@suse.de> --- Hi! This patch follows from my other patch "ceph: fix race in concurrent __ceph_remove_cap invocations", where I see a *lot* of warnings before the NULL pointer. Maybe this could be a pr_warn_once instead, but not sure that would be useful. Note that before commit 4d7ace02ba5c ("ceph: fix mdsmap cluster available check based on laggy number") this was simply ignored without any pr_warn or dout.
