I've been working on moving more and more services away from a reliance on NFS, and I'm wondering what others have done with this issue. I know there are distributed file systems out there, and I have some experience using one of them (mogilefs). I'm curious to know what other people have used to move away from NFS, especially in regards to user-uploaded content. In the web domain specifically, assuming a user uploads content to a specific web server -- what do you do to make that content available across your clusters? I've considered rsync to the rest of the machines in the cluster, or simply to a single content server, but am curious as to what others have done to approach this problem.
I have crontabs across multiple servers using different accounts. The scripts are separated such for a reason, different users for different services, etc. I did some searching for a tool to track what is running where in a central location, but didn't find anything. How are others keeping track of their crontabs? I'm writing some code now to fetch the crontabs from the servers and aggregate them in a central place, but was wondering if anyone has an elegant solution to this problem?
