whats your favorite file system for which purpose?

anyone else using JFS, with or without DRBD?
whats your experiences with it?

In case it happens,
how long does it take to fsck
 per TB of storage
 per million inodes (used)
whats the memory usage?
is the resource consumtion tunable?

how does it generally behave?
 in the presence of disk errors?
 when there is "silent" data corruption
 (like bad ram, or bitflips somewhere down the stack)?
 after hard crashes (power loss)?
 with (concurrent) streaming?
 huge files?
 small files?
 with (loads of concurrent) small writes?
 thousands of files per directory?
 high number of hardlinks?
 high number of symlinks?
 (recursive) deletes?
 with low io-bandwith?
 with high io latency?
 during backup?
 when you want to (online) grow/shrink it?
 compared to XFS?
 compared to EXT3?
 compared to ...?
 ... ?

you'd recommend to use (or just have the habbit of using)
what file system for which purpose? why?

what file system would you love to use with linux,
but there is no port (you trust) available (yet)?
what for? why?

I'm curious for your opinions, habbits, gut feelings,
hard facts, horror and success story after
"catastrophic events"...
so take your time :)
