I’ve had issues before with OpenFiler where doesn’t update the permissions, although they appear correct in the UI. To rectify that, I stumbled upon a one liner that fixed it. Let’s say you have a group called “Trusted” that you want to have full access to your music folder. Here’s the one-liner: [root@files data]# pwd /mnt/openfiler/data [root@files data]# setfacl --recursive -m u:nobody:rwx,g:Trusted:rwx music

Backing up your Openfiler box to S3 While I don’t think most pople would expect to backup their entire NAS/SAN to Amazon’s S3, there might be a few very crucial things you need to backup. I’ve seen an implementation using Ruby and s3sync – something that I do on my server – but I’m trying to migrate everything to Python. Although there are a lot of great tools out there for S3, many of them Python-based, I wanted to do one thing and do it well: have one complete full backup available, and using as little bandwidth as possible. In these regards Duplicity would work well, except I wanted the ability to browse the S3 store using any other tool.
