Quoting Frank Schilder (frans@xxxxxx): If at all possible I would: Upgrade to 13.2.5 (there have been quite a few MDS fixes since 13.2.2). Use more recent kernels on the clients. Below settings for [mds] might help with trimming (you might already have changed mds_log_max_segments to 128 according to logs): [mds] mds_log_max_expiring = 80 # default 20 # trim max $value segments in parallel # Defaults are too conservative. mds_log_max_segments = 120 # default 30 > 1) Is there a bug with having MDS daemons acting as standby-replay? I can't tell what bug you are referring to based on info below. It does seem to work as designed. Gr.
