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. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
