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.

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.

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.

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.
