[Gluster-users] self heal errors on 3.1.1 clients

These errors are appearing in the file /var/log/glusterfs/<mountpoint>.log

[2011-01-26 11:02:10.342349] I [afr-common.c:672:afr_lookup_done] pfs-ro1-replicate-5: split brain detected during lookup of /.
[2011-01-26 11:02:10.342366] I [afr-common.c:716:afr_lookup_done] pfs-ro1-replicate-5: background  meta-data data self-heal triggered. path: /
[2011-01-26 11:02:10.342502] E [afr-self-heal-metadata.c:524:afr_sh_metadata_fix] pfs-ro1-replicate-2: Unable to self-heal permissions/ownership of '/' (possible split-brain). Please fix the file on all backend volumes

Apparently the issue is the root of the storage pool, which in my case on the backend storage servers is this path:

/export/read-only - permissions are:            drwxr-xr-x 12 root root 4096 Dec 28 12:09 /export/read-only/

Installation is GlusterFS 3.1.1 on servers and clients, servers running CentOS 5.5, clients running CentOS 5.2.

The volume info header is below:

Volume Name: pfs-ro1
Type: Distributed-Replicate
Status: Started
Number of Bricks: 10 x 2 = 20
Transport-type: tcp

Any ideas? I don't see a permission issue on the directory or it's subs themselves.

Grrr, looks like the mailing-list software stripped it.  It's also at
