I am using ceph filesystem through ceph-fuse to store product photos and most of the time it works great. But if there is some problem on ceph server, my connected clients start acting crazy. Load on all servers with mounted ceph jumps very high, webserver and other services start to crash. I think, that if ceph server is irresponsive, system creates some queue and as a result everything starts to fail. Simple solution for this is this command: umount -fl /media/ceph && ceph-fuse /media/ceph After that everything gets to normal in a few minutes.
Is it possible to set some timeout to ceph-fuse or something? It is much better if reading photo from ceph will cause error than if everything fails at once. I am using ceph 0.61.7 (today upgraded to 0.61.8), 2x OSD, 1x MDS and 4x mon on different servers with Centos 6.4. I am going to try 0.67, but I think that my main problem is configuration of ceph-fuse mount. I also tried newer kernel with support for mount ceph, but the kernel itself wasn't very stable. Thank you for any tips _______________________________________________ ceph-users mailing list [email protected] http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
