Hello guys,
Sorry if this has been discussed before, but the mailing list archives
are not available and I could not check there first.
I have few strange issues with AFR and one config question.
Here they are ;) :
I have the following setup:
6 servers and 3 clients.
For the test I use only 2 servers in AFR and 1 client
All the software is running under VMWARE virtual machines
Centos 5.1
Kernel: 2.6.18-53.1.21.el5
GFS: glusterfs-1.3.9-1
FUSE: fuse-2.7.3glfs10-1
I export one single partition with XFS filesystem
Here are the config files:
Server config:
================================================
volume brick
type storage/posix
option directory /data/export
end-volume
volume server
type protocol/server
option transport-type tcp/server
option auth.ip.brick.allow *
subvolumes brick
end-volume
================================================
Client Config:
================================================
volume brick1
type protocol/client
option transport-type tcp/client
option remote-host 10.100.1.1
option remote-subvolume brick
end-volume
volume brick2
type protocol/client
option transport-type tcp/client
option remote-host 10.100.1.2
option remote-subvolume brick
end-volume
volume afr1
type cluster/afr
subvolumes brick1 brick2
end-volume
================================================
I mount the volume with the following command:
glusterfs -f /etc/glusterfs/glusterfs-client.vol /mnt/glusterfs
The problems I am facing are the following
Problem 1
a) I start both servers and mount on one client
b) I create some files and dirs on the mount point
c) killall glusterfs on server1
d) create some new dirs and files
e) start glusterfs again on server1
At this point it just does not want to replicate. I tried unmount/mount
the underlaying filesystem or even recreating it but no luck, it just
dont want to replicate. The things get better if I reboot server1
machine. After the reboot replication start to work and replicates the
files.
However another problem pops up.
Problem 1A:
All the synced files/dirs have creation time Jan 1 1970 and I dont see
a way to fix this.
If I create new file on the client the date is fine, however if I start
from clean partition all the synced files have date Jan 1 1970
The time on the servers and clients is in sync with ntpd.
Problem 2
a) I create some files/dirs while both servers are up
b) killall glusterfs on server1
c) mkdir -p /mnt/glusterfs/1/2/3/4/5/6/7/8 - on the client
d) cd /mnt/glusterfs/1/2/3/4/5/6/7/8 - on the client
e) start glusgerfs on server1 - glusterfs -f
/etc/glusterfs/glusterfs-server.vol
f) on the client I do - touch some files here and there
and I get this error:
[root at r3cl1 8]# touch some files here and there
touch: cannot touch `some': No such file or directory
touch: cannot touch `files': No such file or directory
touch: cannot touch `here': No such file or directory
touch: cannot touch `and': No such file or directory
touch: cannot touch `there': No such file or directory
Thank you in advance for any help.
Regards,
Deian
