Hi all.
If cephfs client is in a slow or unreliable network environment, the client will be added
to OSD blacklist and OSD map, and the default duration is 1 hour.
During this time, the client will be forbidden to access CEPH. If I want to solve this
problem and ensure client's normal I/O operation is not interrupted,
are the following two options feasible? which one is better?
1. Set "mds_session_blacklist_on_timeout" to false, and forbid to add slow
clients to blacklist;
2.Just reduce the duration of slow clients joining the blacklist, and change the default 1
hour to 5 minutes.
(set the value of "mon_osd_blacklist_default_expire" to 5 minutes)
Are the two schemes feasible? Will it have a great impact on the data security and
integrity of CEPH?
Can you give me some suggestions?
Thanks.
