[Gluster-devel] Some problems reproduced (strace, test code etc.)

[Mike Machuidel]

Hi everyone,

I reproduced some of the problems I have with GlusterFS. Please read
my report at:
http://www.satl.com/~machuidel/glusterfs/problems/problems.txt

The report describes the following problems:
1) Mmap "no such device" error
2) Low troughput with "dd" its default blocksize
3) cat: -: No such file or directory, when chrooted inside a glusterfs
Linux root

These problems occur with the following (all) combinations I've tested:
- Linux 2.6.18 (FUSE API 7.7) / Libfuse 2.6.5 / Gluster 1.3.0-pre4
- Linux 2.6.18 (FUSE API 7.8) / Libfuse 2.6.3 / Gluster 1.3.0-pre4
- Linux 2.6.18 (FUSE API 7.8) / Libfuse 2.6.5 / Gluster 1.3.0-pre4
- Linux 2.6.20 (FUSE API 7.8) / Libfuse 2.6.5 / Gluster 1.3.0-pre4
- Linux 2.6.20 (FUSE API 7.8) / Libfuse 2.6.3 / Gluster 1.3.0-pre4
- Linux 2.6.18 (FUSE API 7.8) / Libfuse 2.6.5 / Gluster 1.4 (patch 174)

You can find the spec files I am using at:
http://www.satl.com/~machuidel/glusterfs/

The spec files are the same as delivered by default in "examples". No changes.
Glusterfsd and the glusterfs mount are both on the same machine.

Hope it helps.
