Hi. As far as I understand, in case one of the servers had downtime and comes back, GlusterFS automatically synchronizes the files on it when they are accessed. Would such synchronization increase the time the user waits for the file? Meaning the file would be first synchronized, and only then read to user - or it's read immediately and synchronization is done in background?

IF the correct version does NOT exist on the server from which you request the file, then it is synced first then served.>Regards. >_______________________________________________ >Gluster-users mailing list >Gluster-users at gluster.org >http://zresearch.com/cgi-bin/mailman/listinfo/gluster-users
