Hi, Follow up from the suggestion to use any of the following options:
- client_mount_timeout - rados_mon_op_timeout - rados_osd_op_timeout To mitigate the waiting time being blocked on requests. Is there really no other way around this? If two OSDs go down that between them have the both copies of an object, it would be nice to have clients fail *immediately*. I've tried reducing the rados_osd_op_timeout setting to 0.5, but when things go wrong, it still results in the collapse of the cluster and all reads from it. Reducing the rados_osd_op_timeout down to 0.05 seems like a sure way to cause more false positives. But in reality, if an OSD operation can't serve in 150ms, then it's missed the train by over an hour. -- Iain Buclaw *(p < e ? p++ : p) = (c & 0x0f) + '0'; _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
