Glusterfs : unable to copy/move files to the replicated volume

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I am having issue to copy/move files to my replicated volume residing inside the aws volume. I will explain my current setup. I have created two instances in aws and attached a 50GB volume to each of them. I have mounted those volumes at the mount points /gluster_brick1 and /gluster_brick2 respectively. I have created another directory /gluster_brick1/data/ and /gluster_brick2/data/ as two bricks for the glusterfs replications. I have followed the below link for replication setup that was working nicely for me.

https://gopukrish.wordpress.com/glusterfs/

My volume name is datavol and is mounted to each of the servers in the location /home/mytestlo/public_html.


gluster replication is working fine as expected when i create files. But when I copy or  move files to the datavolume, i get error : Remote I/O error.


[root@mytestlocal1 ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/xvda1            9.9G  7.1G  2.4G  76% /
none                  1.8G     0  1.8G   0% /dev/shm
/dev/xvdb              50G  7.1G   40G  16% /gluster_brick1
mytestlocal1.com:/datavol
                       50G  7.1G   40G  16% /home/mytestlo/public_html

[root@mytestlocal1 ~]# cd /home/mytestlo/public_html
[root@mytestlocal1 public_html]# mv /root/phpmyadmin/ /home/mytestlo/public_html/
mv: cannot create directory `/home/mytestlo/public_html/phpmyadmin': Remote I/O error

Only log I was able to find out was :

nfs.log
