[Gluster-users] iscsi and distributed volume

Hi devs, list!

I've got somewhat simple but in same time pretty difficult question. But
I'm running glusterf in production and don't have any option to test myself
:(

say I've got a distributed gluster volume of 2x350GB
I want to export ISCSI target for M$ server and I want it to be 600GB.
I understand, that when I create a large file for ISCSI target with dd, it
will be distributed between two bricks. And here comes the question:

What will happen when

1. one of bricks goes down? Ok, simple - target won't be accessible.
2. would be data available again, when the brick comes back up? (ie failure
due to network or power)

yes, we have backup server and ups and generator, as we are running DC, but
I'm just curious if we will have to restore the data from backups or it
will be available after brick comes back up?

Best regards,
Roman.
