*nix File System Choices?
I need clarification on the following:
1. Which file system is supported by all [or at least most] distros? 2. Which file system is best to be used for handling large volumes of data, which also satisfies 1? Please notify if a thread addressing these issues exists. Thnx

I think the question is more which Unix derivative you are going to use since this will tell you which type of filesystem will be available.
If you talk about distros and mean Linux, you usually go for ext3 or ReiserFS afaik. On AIX we use JFS2 which is the standard there and use it for very large FS'es too. On jfs2 you have (taken from the IBM Information Center about JFS2): Code:
Maximum size for a JFS2-filesystem: 32 TB Maximum file size in JFS2: 16 TB Minimum size for a JFS2-filesystem: 16 MB

Please give an example of "large volumes of data". Linux has a native filesystem (ext2/3) which handles quite large files.
Taken from ext3 - Wikipedia, the free encyclopedia Size limits ext3 has a maximum size for both individual files and the entire filesystem. For the filesystem as a whole that limit is 2**31-1 blocks. Both limits are dependent on the block size of the filesystem; the following chart summarizes the limits[12]: Code:
Block size Max file size Max filesystem size 1KiB 16GiB <2TiB 2KiB 256GiB <4TiB 4KiB 2TiB <8TiB 8KiB 2TiB <16TiB
