[Gluster-users] How to use the bdb storage translator?

[Nguyễn Khánh Duy]

I'm implementing a distributed storage for image thumbnails.
Using GlusterFS 2.0 RC4, I'm planning to create 4 bdb bricks with the
following config (attached is the vol files)
So I built GlusterFS with BDB 4.7 and install it

volume bdb
  type storage/bdb
  option directory /opt/xalo/glusterbdb
  option mode persistent
  option errfile /opt/xalo/glusterbdb/err.log
  option logdir /opt/xalo/glusterbdb/logs
end-volume

The client is mounted like this: glusterfs -f bdbclient.vol
/opt/glusterclient/bdb
I have successfully mounted the server and client. But when I'm
writing to the client directory it failed with the following message:

cannot create regular file `glusterclient/bdb/xyz': No such file or directory

I checked glusterfsd.log and see the following errors:
2009-03-13 22:11:25 E [bdb.c:2750:bdb_readdir] bdb: invalid argument: bfd
2009-03-13 22:11:25 E [bdb.c:1498:bdb_releasedir] bdb: failed to
extract fd data from fd=0x857fbe8
2009-03-13 22:11:35 E [bdb.c:123:bdb_mknod] bdb: bdb_db_get() failed
for path: /posixclient.vol

Also, the glusterfs.log shows:
2009-03-13 22:00:34 E [fuse-bridge.c:924:fuse_err_cbk] glusterfs-fuse:
62: FLUSH() ERR => -1 (File descriptor in bad state)

I don't know what's wrong. Maybe the BDB storage is not POSIX
compliant? So how do we read from and write to this storage?
