1 If you're looking for a flexible filesystem, try btrfs. It is quite nice.
2 It still needs some help in the performance department, but given a recent
3 Linux kernel (say, 3.2) it works wonderfully. I use its snapshots and COW
4 functionality the most.
6 The only downside to it is that it sometimes is slowish when I do many
7 writes in a short period of time. Also, fsync() still takes awhile, so
8 applications that use it liberally, such as dpkg, can run very slow.
9 Things which use SQLite also suffer under heavy write loads.
11 For that reason alone, I wouldn't yet use it on a database server. I would
12 use it on a read-mostly file server, however.
