Hello Jack, yes, I imagine I'll have to do some work on tuning the block size on cephfs. Thanks for the advise. I knew that using mdbox, messages are not removed but I though that was true in sdbox too. Thanks again. We'll soon do benchmarks of sdbox vs mdbox over cephfs with bluestore backend. We'll have to do some some work on how to simulate user traffic, for writes and readings. That seems troublesome. Thanks for the plugins recommendations. I'll take the change and ask you how is the SIS status? We have used it in the past and we've had some problems with it....

...nd is used for all dovecot instances - no need of sharding domains - dovecot is easily load balanced (with director sticking users to the same dovecot backend) On the upcoming upgrade we intent to: - upgrade ceph to 12.X (Luminous) - drop the SSD Cache Tier (because it's deprecated) - use bluestore engine I was said on freenode/#dovecot that there are many cases where SDBOX would perform better with NFS sharing. In case of cephfs, at first, I wouldn't think that would be true because more files == more generated IO, but thinking about what I said in the beginning regarding sdbox vs mdbo...

...emergency data recovery (for purely replicated volumes) even in case of complete failure of the software stack and system disks - just grab the data disks, mount on a suitable machine and copy the data off. Anyone knows of distributed FS with similar easy emergency recovery? (I also run Ceph, but Bluestore seems to be pretty much a black box.)

I don't think it's worth it for anyone. It's a dead project since about 9.0, if not earlier. It's time to embrace the truth and move on. /Z On Sat, 28 Oct 2023 at 11:21, Strahil Nikolov <hunter86_bg at yahoo.com> wrote: > Well, > > After IBM acquisition, RH discontinued their support in many projects > including GlusterFS (certification exams were removed,
