Backup Zarafa with Bacula

Last week I finished migrating our mail/collaboration platform to Zarafa, and as with all things this needs to be backed up. We’re running the Zarafa Enterprise edition which come’s with a backup tool called zarafa-backup which works like this : The first time you run the zarafa-backup tool it creates a data file and an index file refering to the items (folders and mails) inside the data file. The next time you run zarafa-backup it detects the existing files and creates an incremental data file and updates the corresponding index file.

Detect MTU size when using Jumbo Frames

Recently I’ve setup an iSCSI target based on RHEL6 + tgt. After adding Logical Volumes to a target in the tgtd config file, the iSCSI target was discoverable and ready for use. After testing this setup for a few days I wanted to tune the network traffic by enabeling Jumbo Frames. If you search on the interwebz you’ll most likely find information about adding “MTU=9000” ( for RHEL based clones) to the config file of the network interface.

RHEV setup

This blog post comes a little late because I did this RHEV setup at our company more than 6 months ago and it has been living in the drafts folder for some time now. Now with RHEV 3.0 Beta released I tought it’s time to publish this. About a year and a half ago we started looking at alternatives for our VMWare ESXi setup because we wanted to add hypervisor nodes to our 2 existing nodes running VMWare ESXi.

Switched to Jekyll

It has been a while since I last blogged about a “decent” topic and actually it’s been a while blogging about anything. The reason is the lack of time and also some lazyness. But that should change now, and the first step I took was migrating my blog from Drupal to a Jekyll generated website. Not that Drupal is bad or anything, but it’s quite overkill and somehow felt not really productive while creating content.
