Hi, Dernat.

I switched to it from RozoFS. The erasure coding in LizardFS works well 
and we have survived no end of near disasters caused by power failures, 
dead UPS batteries, disk failures and chunkserver crashes: It is robust!

This might be useful if you want to compare LizardFS with alternatives:

As I mentioned before, LizardFS is available pre-compiled in the Debian 
and Ubuntu repositories e.g.:

This makes it very easy to install and it is easy to monitor via a 
cgi-based web-interface. The main reason I stopped using RozoFS was that 
it is difficult to administer and monitor unless you pay for 
Rozo-System's proprietary admin tools. That said, I still think the 
Mojette transform used by RozoFS for erasure coding is much better than 
the Reed-Solomon codes used by LizardFS and most other DFS's.

I gave a talk about RozoFS a while ago that you might be interested in:
