Hi All I have a ceph host (12.2.2) which has 14 OSDs which seem to go down the up, what should I look at to try to identify the issue ? The system has three LSI SAS9201-8i cards which is then connected 14 drives at this time. (option of 24 drives) I have three of these chassis but only one is running right now so I have CEPH set for singe node. I have very carefully looks at the logs files and not found anything which indicates any issues with the controller and the drives. dmesg has these messages. ------------------- [78752.708932] libceph: osd3 10.1.6.2:6834 socket closed (con state OPEN) [78752.710319] libceph: osd3 10.1.6.2:6834 socket closed (con state CONNECTING) [78753.426244] libceph: osd3 down [78753.426640] libceph: osd3 down [78776.496962] libceph: osd5 10.1.6.2:6810 socket closed (con state OPEN) [78776.498626] libceph: osd5 10.1.6.2:6810 socket closed (con state CONNECTING) [78777.446384] libceph: osd5 down [78777.446720] libceph: osd5 down [78806.466973] libceph: osd3 up [78806.467429] libceph: osd3 up [78855.565098] libceph: osd10 10.1.6.2:6801 socket closed (con state OPEN) [78855.567062] libceph: osd10 10.1.6.2:6801 socket closed (con state CONNECTING) [78856.554209] libceph: osd10 down [78856.554357] libceph: osd10 down [78868.265665] libceph: osd1 10.1.6.2:6830 socket closed (con state OPEN) [78868.266347] libceph: osd1 10.1.6.2:6830 socket closed (con state CONNECTING) [78868.529575] libceph: osd1 down [78869.469264] libceph: osd1 down [78899.538533] libceph: osd10 up [78899.538808] libceph: osd10 up [78903.556418] libceph: osd5 up [78905.309401] libceph: osd5 up [78909.755499] libceph: osd1 up [78912.008581] libceph: osd1 up [78912.040872] libceph: osd4 10.1.6.2:6850 socket error on write [78924.736964] libceph: osd8 10.1.6.2:6809 socket closed (con state OPEN) [78924.738402] libceph: osd8 10.1.6.2:6809 socket closed (con state CONNECTING) [78925.602597] libceph: osd8 down [78925.602942] libceph: osd8 down [78988.648108] libceph: osd8 up [78988.648462] libceph: osd8 up [79010.808917] libceph: osd4 10.1.6.2:6850 socket closed (con state OPEN) [79010.810722] libceph: osd4 10.1.6.2:6850 socket closed (con state CONNECTING) [79011.617598] libceph: osd4 down [79011.617861] libceph: osd4 down [79072.772966] libceph: osd14 10.1.6.2:6854 socket closed (con state OPEN) [79072.773434] libceph: osd14 10.1.6.2:6854 socket closed (con state OPEN) [79072.774219] libceph: osd14 10.1.6.2:6854 socket closed (con state CONNECTING) [79073.657383] libceph: osd14 down [79073.657552] libceph: osd14 down [79082.565025] libceph: osd13 10.1.6.2:6846 socket closed (con state OPEN) [79082.565814] libceph: osd13 10.1.6.2:6846 socket closed (con state OPEN) [79082.566279] libceph: osd13 10.1.6.2:6846 socket closed (con state CONNECTING) [79082.670861] libceph: osd13 down [79082.671023] libceph: osd13 down [79115.435180] libceph: osd14 up [79115.435989] libceph: osd14 up [79117.603991] libceph: osd13 up [79118.557601] libceph: osd13 up [79154.719547] libceph: osd4 up [79154.720232] libceph: osd4 up [79175.900935] libceph: osd12 10.1.6.2:6822 socket closed (con state OPEN) [79175.902922] libceph: osd12 10.1.6.2:6822 socket closed (con state CONNECTING) [79176.650847] libceph: osd12 down [79176.651138] libceph: osd12 down [79219.762665] libceph: osd12 up [79219.763090] libceph: osd12 up [79252.405666] libceph: osd11 10.1.6.2:6805 socket closed (con state OPEN) [79252.406349] libceph: osd11 10.1.6.2:6805 socket closed (con state CONNECTING) [79252.462748] libceph: osd11 down [79252.462855] libceph: osd11 down [79285.656850] libceph: osd11 up [79285.657341] libceph: osd11 up [80558.024975] libceph: osd13 10.1.6.2:6854 socket closed (con state OPEN) [80558.025751] libceph: osd13 10.1.6.2:6854 socket closed (con state OPEN) [80558.026341] libceph: osd13 10.1.6.2:6854 socket closed (con state CONNECTING) [80558.652903] libceph: osd13 10.1.6.2:6854 socket error on write [80558.734330] libceph: osd13 down [80558.734501] libceph: osd13 down [80590.753493] libceph: osd13 up [80592.884936] libceph: osd13 up [80592.897062] libceph: osd12 10.1.6.2:6822 socket closed (con state OPEN) [90351.841800] libceph: osd1 down [90371.299988] libceph: osd1 down [90391.238370] libceph: osd1 up [90391.778979] libceph: osd1 up Thanks for any help/ideas Mike _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
