Is it still considered best practice to set 'noout' for OSDs that will
be going under maintenance, e.g., rebooting an OSD ndoe for a kernel
update?
I ask, because I've set this twice now during times which the OSDs would
only momentarily be 'out', however each time I've done this, the OSDs
have become unusable and I've had to rebuild them.
Also, when I _do not_ set 'noout', it would seem that once the node
reboots the OSDs come back online without issue _and_ there is very
_little_ recovery i/o -- I'd expect to see lots of recovery i/o if a
node goes down as the cluster tries to replace the PGs on other OSD
nodes. This further makes me believe that setting 'noout' is no longer
necessary.
I'm running version 12.2.2-12.2.4 (in the middle of upgrading).
Thanks in advance.
