[ceph-users] HEALTH WARN: clock skew detected

Hi All, I have a cluster of 4 nodes with 1 mds, 3 mons and 4 osds. Whenever I do ceph health or ceph -s, it shows a health warning saying clock skew detected in 2 of the 3 mons. When I run a mapreduce application on the cluster, one of the monitors crashes (the one in which the skew is not detecte

Re: [ceph-users] HEALTH WARN: clock skew detected

Are you running ntpd? If so you may need to stop, run ntpdate, and restart ntpd. Sometimes if the clock is too far out of sync ntp won't update the time. On May 5, 2013, at 8:52 AM, Varun Chandramouli wrote: > Hi All, > > I have a cluster of 4 nodes with 1 mds, 3 mons and 4 osds. Whenever I

[ceph-users] Mounting CephFS - mount error 5 = Input/output error

Hi everyone, Thank you for clearing up the issue with the kernel not containing the ceph.ko or rbd.ko modules (and I take that thank you back from the guy who said "oh, you need to load it with modprobe!" because he didn't see that I got the error I sent you from modprobe...) Anyway, I upgraded t

Re: [ceph-users] v0.56.5 released

Hi, The release notes for qemu 1.4 doesn't seem to mention this, so perhaps it is not yet in the newest version? - if so, could someone please direct me to a patch? http://git.qemu.org/?p=qemu.git;a=commitdiff;h=dc7588c1eb3008bda53dde1d6b890cd299758155 Thanks a lot! I have now tested qemu

Re: [ceph-users] HEALTH WARN: clock skew detected

Instead of installing ntpupdate, you can just tell ntpd that it's okay to shift the clock a lot using the '-g' parameter. See: http://superuser.com/questions/518694/ubuntu-12-10-clock-is-wrong I also find it useful to configure the NTP daemons on my monitors as NTP peers so they exchange time dire

Hi Michael, Thanks for your response. No, the ntp daemon is not running. Any other suggestions? Regards Varun ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
