I am currently testing Ceph , l write some code like this:
size_t fd = open("/mnt/aaa", O_CREAT | O_RDWR | O_APPEND , 0755);
then l can not write buffer to the fd, 1 think there is something wrong in :
int ceph_flags_to_mode(int flags)
{
...
if ((flags & O_ACCMODE) == O_RDWR)
mode = CEPH_FILE_MODE_RDWR;
else if ((flags & O_ACCMODE) == O_WRONLY) //?
mode = CEPH_FILE_MODE_WR;
else
mode = CEPH_FILE_MODE_RD;
...
}
if change the "(flags & O_ACCMODE) == O_WRONLY" to "(flags &
O_ACCMODE) == O_ACCMODE", l can write success!
another problem, I am trying to use a Ceph cfuse client to mount Ceph
DFS(/mnt/) and
set up a samba server to share the mount point(/mnt),l find it not so
fast as expected， l analyse the log :

method:getxattr path:security.capability
the SimpleMessenger thread replyed the osd ,it wait ,the problem is
the next FUSE operation is very slowly,
why the fuse thread and SimpleMessenger thread can not work in parallel
anybody have the same problem with me?
