Hello Ceph team,
I have seen some pretty strange behavior of ceph release 0.15 under
Ubuntu 9.0.4 (gcc 4.3.3) and maybe you are interested in it:
First, I have got the following compile error message under Ubuntu
9.0.4 (gcc 4.3.3)
> st_ioctls.c' || echo './'`client/test_ioctls.c
> In function ‘open’,
> inlined from ‘main’ at client/test_ioctls.c:34:
> /usr/include/bits/fcntl2.h:51: error: call to ‘__open_missing_mode’
> declared with attribute error: open with O_CREAT in second argument
> needs 3 arguments
The reason is that the open call in the following code of client/
test_ioctrls.c has no third parameter.
It can easily be fixed by adding e.g. 0x644.
The other problem is this:
Another problem I have normally mounting ceph via cfuse as well as via
the RADOS S3 Gateway is:
> >> cfuse -m <ip of monitor>:6789/ /mnt/ceph/
> bound to 0.0.0.0:6802/5304/0, mounting ceph
> terminate called after throwing an instance of

The backtrace is (similar if using rgw or rgw_admin):

The mon log file states:

Probably the communication of the message between monitor and client
is not totally correct.
However, the error is strange anyway, because the ceph.conf states:
[mount /]
allow = %everyone
The client is treaded as not authorized, because the ExportEntry of
the mountpoint "/" had no ExportAddrEntry items.
Reason for that: The name of the group in the GroupManager::get_group
method was not trimmed (it was still " %everyone") which fails,
because only the first character is tested to be "%". The was caused
by the cut and pasting from the browser which included some strange
UNICODE fragments that looked like a normal space in various editor
incl. vi, gdb, but it was not and therefore also not trimmed correctly.
> od -c ceph.conf
[ m o u n t / ] \n a l l o w = 302
240 % e v e r y o n e \n
After changing the "space", ceph mounted fine. It would be great if
the configuration parser would reject files with invisible characters.
I don't know if this observations help. Thanks for the good work.
Best Regards
Dirk
