Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

What others think

a little bit more explanation would have been nice.

Also, who uses andrew file system anymore? w-o-w

@linuxrawkstar "more explanation"? Ok, AFS fileservers store data within "volumes" (which reside within fileserver "partitions"). These volumes get mounted on mountpoints which are then accessible as directories.

AFS volumes can be replicated across many fileservers.

Sometimes volumes can be in a "locked" state and and AFS administrator would want to be able to find these.

If well configured, AFS filespace is robust and has many benefits.

Here is the public list of AFS cells on the Internet (aka "CellServDB") => http://dl.central.org/dl/cellservdb/CellServDB
