This is with release 1.3.9. Not much more that seems relevant turns up in the logs with -L DEBUG (DNS chatter, mentions that the 2nd server isn't talking (glusterfs is switched off on it because that causes the lock-up). This gets logged when I try to cat ~/.bashrc: 2008-05-20 09:14:08 D [fuse-bridge.c:375:fuse_entry_cbk] glusterfs-fuse: 39: (34) /gordan/.bashrc => 60166157 2008-05-20 09:14:08 D [inode.c:577:__create_inode] fuse/inode: create inode(60166157) 2008-05-20 09:14:08 D [inode.c:367:__active_inode] fuse/inode: activating inode(60166157), lru=7/102 4 2008-05-20 09:14:08 D [inode.c:367:__active_inode] fuse/inode: activating inode(60166157), lru=7/102 4 2008-05-20 09:14:08 D [fuse-bridge.c:1517:fuse_open] glusterfs-fuse: 40: OPEN /gordan/.bashrc 2008-05-20 09:14:08 E [afr.c:1985:afr_selfheal] home: none of the children are up for locking, retur ning EIO 2008-05-20 09:14:08 E [fuse-bridge.c:692:fuse_fd_cbk] glusterfs-fuse: 40: (12) /gordan/.bashrc => -1 (5) On the command line, I get back "Input/output error". I can ls the files, but cannot actually read them. This is with only the first server up. Same happens when I mount home.vol via fstab or via something like: glusterfs -f /etc/glusterfs/home.vol /home I have also reduced the config (single process, intended for servers) to a bare minimum (removed posix lock layer), to get to the bottom of it, but I cannot get any reads to work: volume home1 type storage/posix option directory /gluster/home end-volume volume home2 type protocol/client option transport-type tcp/client option remote-host 192.168.3.1 option remote-subvolume home2 end-volume volume home type cluster/afr option read-subvolume home1 subvolumes home1 home2 end-volume volume server type protocol/server option transport-type tcp/server subvolumes home home1 option auth.ip.home.allow 127.0.0.1,192.168.* option auth.ip.home1.allow 127.0.0.1,192.168.* end-volume On a related node, if single-process is used, how does GlusterFS know which volume to mount? For example, if it is trying to mount the protocol/client volume (home2), the obviously, that won't work because the 2nd server is not up. If it is mounting the protocol/server volume, then is it trying to mount home or home1? Or does it mount the outermost volume that _isn't_ a protocol/[client|server] (which is "home" in this case)?
