I use ceph for HA-cluster. Some time ceph rbd go to have pause in work (stop i/o operations). Sometime it can be when one of OSD slow response to requests. Sometime it can be my mistake (xfs_freeze -f for one of OSD-drive). I have 2 storage servers with one osd on each. This pauses can be few minutes. 1. Is any settings for fast change primary osd if current osd work bad (slow, don't response). 2. Can I use ceph-rbd in software raid-array with local drive, for use local drive instead of ceph if ceph cluster fail? _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
