It is just used as another copy of data.
I feel like using such a local brick optimizes the performance very
much.
In that case you should set the option read-subvolume to "brick",
so that reads go to the local brick.
When I use this option, and the file isn't available in "brick", does
it automatically loads the file from a fileserver?
No, we change file in the mounted directory.
So the new files is immediately replicated to the second fileserver.
Ok. Can you explain in more detail where you're doing the modification
from, and when self-heal is triggered?
The glusterfs mounted directory is alwasys called "/srv".
On Fileserver 1:
I copy a file from a local disk ('/root' for exaple) to '/srv/xxx/
yyyy.gif'.
Doing it on console or per ftp its the same here.
Making a 'ls -lh /srv/xxx/' shows the new file.
On FIleserver 2:
Making a 'ls -lh /srv/xxx/' shows the new file.
On Webserver:
Making a 'ls -lh /srv/xxx/' the first time shows the new file.
Making again 'ls -lh /srv/xxx/' shows the old file :-(
The log on the Webserver says:
afr: self-healing file /www/XXXX/yyyyyyy.gif from subvolume brick to 2
other
And now the old file ist now on the Fileserver again ... :-(
I hope this helps ...
