Bug found by Ken:

upgraded argonaut cluster to bobtail [burnupi16, burnupi17, burnupi18] and the client[burnupi62] is running on argonaut version of ceph-fuse

now, trying to ceph-fuse mount from the client without the client.admin.keyring segfaults,

ubuntu@burnupi62:~$ sudo ceph-fuse -c ceph-auth-on.conf -m 10.214.134.20:6789 /mnt/qa

ceph-fuse35759: mount failed: (33) Numerical argument out of domain

However, copying the client.admin.keyring on the client and trying ceph-fuse mount is successful.

Did you check for similar bugs? Not certain but I believe this has been fixed in a dev release since then. (Maybe should get cherry-picked into stable, I guess?)

I tried installing ceph-fuse from next branch, and I dont see any segfault.

ubuntu@burnupi62:~$ sudo ceph-fuse -v
ceph version 0.55-192-ge4d0aea (e4d0aeace187afee6313d803511ba595e91dd7ed)

ubuntu@burnupi62:~$ sudo mkdir /mnt/test

ubuntu@burnupi62:~$ sudo ceph-fuse -c ceph-auth-on.conf -m 10.214.134.20:6789 /mnt/test
ceph-fuse49075: starting ceph client
ceph-fuse49075: ceph mount failed with (2) No such file or directory
2012-12-10 20:06:12.315136 7f1cc4e30780 -1 monclient(hunting): failed to open keyring: (2) No such file or directory
ceph-fuse49073: mount failed: (2) No such file or directory

And after copying the keyring, it works well.

However I think we may have to cherry pick the fix to stable branch to avoid a likely event of segfault.
