[Gluster-devel] big problem with unify in rc2

[Dan Parsons]

After upgrading to rc2, I'm getting unify errors for a lot of files. If I
try to read one of these files, I get an I/O error. Here are the
corresponding lines from gluster log:
2009-02-25 13:42:49 E [unify.c:1239:unify_open] unify:
/bio/db/blast/blastp-nr_v9/blastp-nr.19.pni: entry_count is 1
2009-02-25 13:42:49 E [unify.c:1242:unify_open] unify:

2009-02-25 13:42:49 E [unify.c:1246:unify_open] unify: returning EIO as file
found on onlyone node
2009-02-25 13:42:49 E [fuse-bridge.c:667:fuse_fd_cbk] glusterfs-fuse: 4152:

error)

No errors on any of the servers, and I've verified that the files DO exist
on the server. Here's my client config:
