Hi,
Simple scenario, server serves directory to client
After some time clinet is not able to dir, df (any I/O operation blocking
forever)
Reset of server glusterfsd does not help, signalling --TERM/ --KILL on client
side glustefs process either,
I am unable to umount:
[matkor at client ~]$ sudo umount /glusterdir
umount: /glusterdir: device is busy
umount: /glusterdir: device is busy
How can I solve it without resetting client?
Thanks in advance for any help.
I am using glusterfs 2.0.0-0.rc1
[matkor at client ~]$ cat /etc/glusterfs/server_simple_volume.vol
volume server_simple_volume
type protocol/client
option transport-type tcp/client # for TCP/IP transport
option remote-host 192.168.3.1 # IP address of the remote brick
option remote-subvolume simple_volume # name of the remote volume
end-volume
[matkor at server /etc/glusterfs]$ cat glusterfs-server.vol
volume simple_volume
type storage/posix # POSIX FS translator
option directory /glusterdir
end-volume
volume server
type protocol/server
option transport-type tcp/server # For TCP/IP transport
option client-volume-filename /etc/glusterfs/glusterfs-client.vol
subvolumes simple_volume
option auth.ip.simple_volume.allow 127.0.0.1,192.168.3.*,10.10.*
end-volume
[matkor at server /etc/glusterfs]$ cat /etc/glusterfs/glusterfs-client.vol:
volume server_simple_volume
type protocol/client
option transport-type tcp/client # for TCP/IP transport
option remote-host 192.168.3.1 # IP address of the remote brick
option remote-subvolume simple_volume # name of the remote volume
end-volume
