That failure could be an actual TCP/IP stack error; it could be because a different thread killed the connection and it's now closed. If you've just got one of these and didn't see other problems, it's innocuous — I expect the most common cause for this is an OSD getting marked down while IO is pending to it. :) -Greg > > Can someone "decode" the above message, or direct me to some document where > I could read more about it? > > We have ceph 0.94.10. > > Thank you, > Laszlo > _______________________________________________ > ceph-users mailing list > ceph-users@xxxxxxxxxxxxxx > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
