Dear developers! Today i tried ceph on my new linux cluster so far i use 1 monitor-only server and 2 storage-only nodes with 2TB volumes each, (6-disk RAID-0) all connected with Gigabit Ethernet. OpenSuSE v11.0 everywhere (in the future -- up to 20 storage nodes.) That is an experimental cluster, so i'd be glad to test your system so far.
The feature i liked, is that when i switched off one of the two storage nodes, all data was still accessible !!! this is a major reason why i'd preffer this solution over others (like lustre, coda and etc, which are much more complex to set up, not speaking about gfs and ocfs) with 2 nodes running i have read/write ratio about 20MB/sec (i believe that was due to debugging checks, i built it with default options, from the default GIT-branch) i used btrfs for osd volumes. the only bug so far: when monitor server goes down, and ceph volume was not unmounted, it stalls. nothing happens even when monitor server is up again -- i get messages like: ceph: mds0 session probably timed out, requesting mds map Sincerelly, Vitaly. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Ceph-devel mailing list Ceph-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ceph-devel
