Stephan - Dovecot has been a challenge in the past. We don't specifically test with it here, if you are interested in using it with Gluster I would suggest testing with 3.1.1, and always keep the index files local, that makes a big difference. Thanks, CraigWell, Craig, I cannot follow your advice as these are 32 bit clients and AFAIK you said 3.1.1 is not expected to be used in such an environment. Really quite a lot of interesting setups for glusterfs turn around mail servers, I judge it to be a major deficiency if the fs cannot be used for such
Quick interjection here: We have some customers using Dovecot on our storage units with GlusterFS 3.0.x. There are some issues, usually interactions between dovecot and fuse/glusterfs. Nothing that can't be worked around. We are seeing strong/growing interest from our customer base in this use case.
Craig's advice is spot on.
purposes. You cannot expect voting for glusterfs if there are other options that have no problems with such a standard setup. I mean is there something more obvious than mailservers for such a fs?
Hmmm ... apart from NFS (which isn't a cluster file system), which has a number of its own issues, which other cluster file system are you referring to, that don't have these sorts of issues? Small file and small record performance on any sort of cluster file system is very hard. You have to get it right first, and then work on the performance side later.
Honestly, I got the impression that you're heading away from the mainstream fs usage to very special environments and usage patterns. I feel very sorry about that because 2.X looked very promising. But I did not find a single setup where 3.X could be used at all.
While I respect your opinion, I do disagree with it. In our opinion 3.1.x has gotten better than 3.0.x, which was a huge step up from 2.0.x.
