Re: [Gluster-users] Rsync

It would be nice to remember my thread about _not_ copying data initially to gluster via the mountpoint. And one major reason for _local_ feed was: speed. Obviously a lot of cases are merely impossible because of the pure waiting time. If you had a live setup people would have already shot you...

Hello all, last week we saw our first try to enable something like a real-world environment on glusterfs fail. Nevertheless we managed to get a working combination of _one_ server and _one_ client (using a replicate setup with a missing second server). This setup worked for about 4 days, so

Hello all, after playing around for some weeks we decided to make some real world tests with glusterfs. Therefore we took a nfs-client and mounted the very same data with glusterfs. The client does some logfile processing every 5 minutes and needs around 3,5 mins runtime in a nfs setup. We found
