Look for iowait and other disk metrics: iostat -x <list of /dev/disks> 1 high iowait with low throughput could indicate a disk problem. dmesg might show something unless you are using consumer disks that tend to mask errors from the OS. get smartmontools and do smartctl -H on each disk and see if smart thinks the disk is okay, then smartctl -a on each disk and look for evidence of errors (uncorrectable etc) James _______________________________________________ ceph-users mailing list [email protected] http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
