similar to: [ceph-users] dovecot + cephfs - sdbox vs mdbox

I'm sending this message to both dovecot and ceph-users ML so please don't mind if something seems too obvious for you. Hi, I have a question for both dovecot and ceph lists and below I'll explain what's going on. Regarding dbox format (https://wiki2.dovecot.org/MailboxFormat/dbox), when using sdbox, a new file is stored for each email message. When using mdbox, multiple

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.

Hi, some time back we had similar discussions when we, as an email provider, discussed to move away from traditional NAS/NFS storage to Ceph. The problem with POSIX file systems and dovecot is that e.g. with mdbox only around ~20% of the IO operations are READ/WRITE, the rest are metadata IOs. You will not change this with using CephFS since it will basically behave the same way as e.g. NFS. We

Hi, did you check in unstable ? https://tracker.debian.org/pkg/dovecot 2018-04-26 16:43 GMT-04:00 Webert de Souza Lima <webert.boss at gmail.com>: > hmm I think I should use stretch instead of jessie, OR I should use a > stretch-backport repos, right? > > > Regards, > > Webert Lima > DevOps Engineer at MAV Tecnologia > *Belo Horizonte - Brasil* > *IRC NICK -

Hey Aki Tuomi, how are you doing? I have tried many ways for getting 2.2.35 pre-built installed via 'apt-get install' in Debian Jessie and Stretch using the official repos. The reason I prefer to install pre-built instead of compiling it is because the I run it on dockers, so it's a lot easier and automated to just apt-get install it. I was using 2.2.31 devel in Debian Jessie, I

Hi, I can't figure how to install latest stable dovecot version 2.2.35 in Debian Jessie If I follow this guide <https://repo.dovecot.org/>, it ends up installing 2.3 If I follow this guide <https://wiki.dovecot.org/PrebuiltBinaries#preview>, it ends up installing either 2.2.13 if I use "stable" or 2.2.36 alpha if I use "jessie" I see that 2.2.35 seems to be

Hello Florent, How did you proceed with the upgrade? Did you follow the recommended steps guide to upgrade ceph? (mons first, then OSDs, then MDS) Did you interrupt dovecot before upgrading the MDS specially? Did you remount the filesystem? Did you upgrade the ceph client too? Give people the complete scene and someone might be able to help you. Ask on ceph-users list too. Regards, Webert

Hi! 2.2.35 is not unstable, but apparently it is in debian distribution, which is called 'unstable'.

Hello, The following errors are constantly popping up for 2 accounts. I can't get it fixed, I did doveadm backup to another account, the same happens in the new account. I did doveadm force-resync, the problem persists. I'm using dovecot 2.2. 2017-08-18T11:46:12.472821881Z Aug 18 11:46:12 lmtp(ramon.lacerda at alliar.com): Warning: mdbox

Oh thank you Cedric, I hadn't check that. So 2.2.35 is unstable, huh? I'll deploy 2.2.34 instead. Thank you!

Hi, I have a user account that had almost 20GB of emails and now they're missing. Only a few are available trough IMAP or doveadm. I can see in /path/to/mailbox/storage that thousands of "m." files are still there, summing up 19GB of files. doveconf -n http://termbin.com/7lgc I have tried: accessing via IMAP accessing via doveadm search/fetch/mailbox status doveadm index doveadm

hmm I think I should use stretch instead of jessie, OR I should use a stretch-backport repos, right?

Hi, often I run into the situation where a dovecot server goes down for maintenance, and all users get concentrated in the remaining dovecot server (considering I have 2 dovecot servers only). When that dovecot server comes back online, director server will send new users to it, but the dovecot server that was up all the time will still have tons of clients mapped to it. I suggest the director

Hi, I'm testing out ceph_vms vs a cephfs mount with a cifs export. I currently have 3 active ceph mds servers to maximise throughput and when I have configured a cephfs mount with a cifs export, I'm getting a reasonable benchmark results. However, when I tried some benchmarking with the ceph_vms module, I only got a 3rd of the comparable write throughput. I'm just wondering if
