Hello,
I'm running glusterfs 1.4.0pre5 (glusterfs--mainline--3.0--patch-359)
and fuse-2.7.3glfs10 on 2 machines with AFR with client side
replication. My test setup is: 2 glusterfs servers and 2 glusterfs
clients,i.e. the two mashines (server1 and server2) are configured as
server and client. I was getting occasional Input/output error when
listing glisterfs (afr) directory on server1.
The glusterfs client log messages are:
2008-10-06 12:55:02 E [afr_self_heal.c:123:afr_lds_setdents_cbk]
afr-wwwroot: op_ret=-1 op_errno=17
2008-10-06 12:55:02 E [afr_self_heal.c:123:afr_lds_setdents_cbk]
afr-wwwroot: op_ret=-1 op_errno=17
2008-10-06 12:55:02 E [fuse-bridge.c:398:fuse_entry_cbk]
glusterfs-fuse: 196: LOOKUP() / => -1 (Input/output error)
The messages in the glusterfs server log are:
2008-10-06 12:54:01 C [posix.c:2756:ensure_file_type] wwwroot: entry
/wwwroot//xxx.xxxx.xx is a different type of file than expected
In afr directory there are many symlinks and the file
/wwwroot//xxx.xxxx.xx is a symlink. So I must stop glusterfs client
and server processes on server1, remove the symlinks, start them again
and listing the glusterfs directory to remove the problem.
My config files on the two client and server mashines are:
cat /etc/glusterfs/glusterfs-server.vol
volume wwwroot
type storage/posix
option directory /wwwroot
end-volume
volume server
type protocol/server
option transport-type tcp/server
subvolumes wwwroot
option auth.addr.wwwroot.allow 10.0.0.*,127.0.0.1
end-volume
cat /etc/glusterfs/glusterfs-client.vol
volume client-server1-wwwroot
type protocol/client
option transport-type tcp/client
option remote-host 127.0.0.1
option remote-subvolume wwwroot
end-volume
volume client-server2-wwwroot
type protocol/client
option transport-type tcp/client
option remote-host 10.0.0.100
option remote-subvolume wwwroot
end-volume
volume afr-wwwroot
type cluster/afr
subvolumes client-server1-wwwroot client-server2-wwwroot
end-volume
I think the problem does not exist on version 1.3.12.
Maybe it is a bug or can you help me what is wrong?
Thanks,
Snezhana
