We're moving to an HA solution in my SaaS environment, and I'm looking at using
Gluster 2.09 (32 bit hardware) and CentOS 5.5.
This is up and running as such:
gluster1 -- data server
gluster2 -- data server
app1 -- app server (mounts the glusterfs in /home)
app2 -- app server (ditto)
Here's my question.
Test 1:
create /home/foo and add 10 files on app1
ls /home/foo on app2 -- I see them
ls /data/export/foo on gluster1/gluster2 -- I see them
Test2:
rm -rf /home/foo on app2
ls on the other 3. The directory is gone
Test3:
create /home/foo and add 5 files on app1
shutdown gluster2
add 5 more files
startup gluster2
ls /data/export/foo on app1/app2/gluster1 -- I see 10 files
ls /data/export/foo on gluster2 -- I see only the 5 files created when the
server was up.
How is the failover/replication supposed to work in the situation that one of
the backend RAID1 servers goes down?
