I used docker installation with default configuration. And I googled my problem and saw at reddit this post: https://www.reddit.com/r/ceph/comments/10bcwra/nfs_cluster_ha_not_working_what_am_i_missing/ I added this configuration with "check" option in my installation. Now haproxy detects fail of node but vdbench show writes is lost even if one node from 5 is down. Also I used mount -o vers=4.1 which is more stable than 4.2 as I see. How can i set up true HA before using this in a production? _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
