A client’s block device should write simultaneously to several storage nodes

A client’s block device should not fail as long as not all storage nodes backing it went down

The master should automatically…

Best Approach for subnetting/VLANing traffic?

Our network is currently setup with no subnets or VLANs. We are looking at going to VoIP so this needs to change before VoIP is installed. I believe that we want to use VLANs to separate Voice and Data, am I correct on saying that? Also, I would like to separate our engineering department off our main data because of their file sizes and the time it…

How to make a Linux software RAID1 detect disc corruption?

This is one of the nightmare days: A virtualized server running on a Linux SW-RAID1 runs a VM that exhibits random segfaults in seemingly random codechunks.

While debugging I find that a file gives different md5sums on each and every run. Digging deeper I find this: The raw disc partitions that make up the RAID1 mirror contain 2…

Does anyone know if you can setup a Skype-to-SIP gateway on your network?

I tried Uplink, which works wonders, but only on Windows and with Skype on the same machine… It would be awesome if you could put that program on any machine and then use it as a gateway for Skype, from another machine. With port forwarding maybe?

Basically I’m trying to use Skype in Linux as a softphone…
