similar to: dovecot replication (active-active) - server specs

Hi, I replaced HDDs in my home server and reinstalled the OS (Ubuntu 17.04). Since I had some time I reviewed my Dovecot configuration and changed a couple of things, including mailbox format. Now I would like to migrate e-mail (about 20G -- I use this server as an e-mail archive). The Maildir is available on the (old) hard disk. The new dovecot is running. What should I use? Would mbsync work?

Silly question? Which is preferred? MailDir or Mbox? (directory vs flat file) How would you do this when migrating from an old server to a new one?

Hi Everyone, I am stack between two identical systems (2U Twin2, 4 nodes, SuperMicro) servers that have the same exact specs except for HDDs. These nodes will all either have Asterisk installed with CentOS or will have Asterisk install in virtual environment. Option 1: *12* x 3.5" HDD (3 HDDs per node) Option 2: *24* x 2.5" HDD (6 HDDs per node) **both options come to the same price.

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

I installed a Centos 4.x system using a lvm install across four HDDs. It is my first install using LVM. System had a power-failure and stopped booting up. A new trainee simply took out the HDDs and restarted the file-server on a fresh HDDs. Now the problemis that the four HDDs have data. But the order of the HDDs (of install....1st primary, 2nd primary etc.) is unknown. Earlier we used to boot

Thanks Jack. That's good to know. It is definitely something to consider. In a distributed storage scenario we might build a dedicated pool for that and tune the pool as more capacity or performance is needed.

Hello, I would like to use nas4free under xcp 1.6. I install it under full HVM using "other install media". Now I am attaching 4 hdds as external disks. The vm sees at most two hdds, I suppose because of bios support (1 boot + 1 cdrom + 2 hdds= 4 hdds). I need to use more disks, is it possible? If not, it seems to me a serious limit. Mario

My future plan currently looks like this for my VPS hosting solution, so any feedback would be appreciated: Each Node: Dell R210 Intel X3430 Quad Core 8GB RAM Intel PT 1Gbps Server Dual Port NIC using linux "bonding" Small pair of HDDs for OS (Probably in RAID1) Each node will run about 10 - 15 customer guests Storage Server: Some Intel Quad Core Chip 2GB RAM (Maybe more?)

Hi, I am planning on running on test between maildir and mdbox to see which is a better fit for my use case. And I'm just looking for general advice/recommendation. I will post any results I obtain here. Important question: I have multiple users hitting the same email account at the same time. Can be a problem with mdbox? (either via thunderbird or with custom webmail apps). I remember

Hello all, I am thinking about a new laptop. I see that there are a number of higher-performance models (incidenatlly, they are also marketed as "gamer" ones) which offer two SATA 2.5" bays and an SD flash card slot. Vendors usually position the two-HDD bay part as either "get lots of capacity with RAID0 over two HDDs, or get some capacity and some performance by mixing one

Hi, I have a failover cluster for mail server with: Ubuntu12.04 + DRBD (for block replication) + Ext4 filesystem + Dovecot-2.0.19-2 with Mdbox It works fine with ~50k accounts. My cluster design: http://adminlinux.com.br/cluster_design.txt I plan to test Dovecot Replication with dsync to build an active/active cluster with load balancing. Can anyone direct me to some literature? A tutorial

Hello, Not sure where to start looking, so I start with the program that threw the message. Not sure what information I need to provide or the preferred formatting.

I found mptutil on LSI Logic site but it just shows me configuration in quite cryptic form. Thanks, Mindaugas
