Hi everybody, I didn't find any ceph-users list so I post here. If this is not the right place to do it please let me know. I'm currently trying to test ceph but I'm probably doing something wrong because I have a really strange behavior. Context: Ceph compiled and installed on five Centos6 machines. A BTRFS partition is available on each machine. This partition is mounted under /data/osd.[0-3] Clients are using cfuse compiled for FC11 ( 2.6.29.4-167.fc11.x86_64 ) What happen: I configured everything in ceph.conf, started ceph daemons on all nodes. When I issue ceph health, I have a HEALTH_OK answer. I can access the filesystem through cfuse and create some files on it, but when I try to create files bigger than 2 or 3 Mo, the filesystem hangs. When I try to copy an entire directory ( ceph sources for instance) I have the same problem. When the system is in this state, the cosd daemon die on OSD machines: [INF] osd0 out (down for 304.836218) Even killing it doesn't release the mountpoint : cosd 9170 root 10uW REG 8,6 8 2506754 /data/osd.0/fsid cosd 9170 root 11r DIR 8,6 4096 2506753 /data/osd.0 cosd 9170 root 12r DIR 8,6 24576 2506755 /data/osd.0/current cosd 9170 root 13u REG 8,6 4 2506757 /data/osd.0/current/commit_op_seq I tried to change some parameters but it results in the same problem: Tried both with the 0.34 and 0.35 releases and using both BTRFS or EXTR3 with user_attr attribute. I tried the cfuse client on one of the Centos 6 machine. I read everything on http://ceph.newdream.net/wiki but I can't figure out the problem. Does somebody have any clue of the problem's origin ?
