Hi
I tried to do offline read optimization[1] this morning but I am now
unable to map the RBDs in the pool.
I did this prior to running the pg-upmap-primary commands suggested by
the optimizer, as suggested by the latest documentation[2]:
"
ceph osd set-require-min-compat-client reef
"
The command didn't complain and the documentation stated it should
failed if any pre-reef clients were connected so I thought all was well
and rad the pg_upmap_primary commands.
Can I simply remove the applied pg_upmap_primary settings somehow to my
RBDs back while investigating?
Mvh.
