Ceph » Linux kernel client

Tried mounting with IPv6 today, but it failed, the config:

[global]
        auth supported = none
        debug ms = 1
        ms bind ipv6 = true
        keyring = /etc/ceph/keyring.bin

[mon]
        mon data = /srv/ceph/mon$id
        mon lease wiggle room = 0.5
        debug mon = 20

[mon0]
        host = node13
        mon addr = {2001:16f8:10:2::c3c3:3f9b}:6789

[mon1]
        host = node14
        mon addr = {2001:16f8:10:2::c3c3:2e5c}:6789

Verified cluster status with "ceph -s", cluster is working fine, all OSD's, MON's and MDS'es are online.

When mounting you get:

root@client02:~# mount -t ceph -o secretfile=/etc/ceph/secret,name=admin [2001:16f8:10:2::c3c3:3f9b]:/ /mnt/ceph
mount error 5 = Input/output error
root@client02:~# rmmod ceph
root@client02:~# mount -t ceph -o secretfile=/etc/ceph/secret,name=admin [2001:16f8:10:2::c3c3:2e5c]:/ /mnt/ceph
mount error 5 = Input/output error

Verified if i could connect to the monitor and yes, that is possible from the client02. Everything seems to work, except for mounting.

Using the "master" branch, since this one support IPv6 addresses when mounting.

my bad, there was a fix in unstable that wasn't in master. moved that over, and it gets rid of the -97 error for me.
