If your need is for storing large files and having fast deletes, then these should be a good choice, and were both recommended by MythTV users a few years ago when I set up my MythTV box. I'd recommend doing some data mining in their mailing list to see what the latest recommendations are. I ended up choosing XFS, and while I haven't tried JFS to compare, I did find the XFS tools - at least the ones packaged for Ubuntu - to be a bit buggy, and I had to file a few bugs: https://bugs.launchpad.net/ubuntu/+source/xfsprogs/+bug/81711 https://bugs.launchpad.net/ubuntu/+source/xfsprogs/+bug/81717 To work around the problems I just reverted to a prior version. They might have been Ubuntu-specific build problems, and they have probably since been resolved. But these bugs gave me the impression that XFS isn't widely used on Ubuntu. > I have a project that may require a million plus directories. That sounds like you want a file system optimized for file indexing, rather than large files. RiserFS probably was the best in that area. I don't recall if Ext4 addresses this, and as Jerry mentioned may not be ready for production in your time frame. You may need to resort to a hybrid solution, with an index stored in a real database. -Tom -- Tom Metro Venture Logic, Newton, MA, USA "Enterprise solutions through open source."
