Could I possibly have some feedback on what the recommended filesystems are? I've heard of ReiserFS but was wondering what other options there are and how they compare.
Reiser has traditionally been a very good choice for maildir because it has infinite inodes, it is very fast on directories with large numbers of files, and it does sub allocation so small files take less space. And it's very fast. Maildir is the area where Reiser does best.
Thanks for this - I have heared many maildir admins laud Reiser. How is it for ongoing stability and reliability? I suppose with using any non-mainstream technology (ie ext stuff) the admins concern is that it is less well tested for bugs and corruption.
three or four years ago we had a major reiserfs corruption due to faulty memory modules (as I know now). The result was a completely unusable and unrepairable partition that could eventually, after two weeks or so, be repaired with the help of Hans Reiser himself. Even though I really appreciated direct involvement of the main developer, I will avoid it by any means.
Eg i see many people saying xfs is great but who wouldn't think of having it put into production.
XFS is one of the most mature filesystems around for UNIX systems. It has been developed by SGI for its IRIX OS for a _very_ long time. If POSIX compliance (ACLs!!), out of the box quota support, scalability (up to 9 million terabytes max. capacity, IIRC), sophisticated backup/restore facitilites (including snapshots and more), online file defragmentation and much more are of importance for you, then go for XFS ... well, and you certainly guessed it, we are using it for almost all of our servers :-)
