Just be very sure that you have ext4 support in your kernel, otherwise you have a problem. ext4 should be listed in /proc/filesystems . Of course, the root filesystem is mounted before /etc/fstab can be read... :-) ignoring initrd for now. > > There is a lot of FUD about reiserfs. > > Reiserfs can take a hard crash without needing an fsck just like > ext[34] can.

Not necessarily, but with reiser it's documented that reiser expects _no_ storage failure whatsoever, so some form of RAID with redundancy is a must. You _are_ screwed if you happen to have an image of a reiser filesystem on your reiser filesystem, as the fsck will see the reiser markers and merge that image into your real filesystem. I've avoided reiser since Hans got jailed for murder (but that's another topic :-) > I have seen it happen. It is rare that reiserfs needs an fsck but if > it does the fsck is destructive. I've seen a reiser fsck eat the filesystem about 5 in 100 times. (I used to help administer a server farm with 200 servers, running on reiser at the time.) > but the same is not true on Gentoo.

I used XFS with NFS for my dreambox (DVB satellite receiver), storing multi-GB recordings. Of course there was only one NFS client. That worked great. It's especially good at large files. That said, ext4 has become quite amazing and even if it does fall mostly over, chances of extracting files from the broken fs are excellent. btrfs is promising to be quite cool as well, I love the snapshot system. However having had some bad experiences with corruption I'm hesitant to use it for anything critical for now. That _was_ a number of years ago, on a 8TB filesystem which got hammered pretty badly with daily backups (each being snapshotted and deleted after some time), so not really representative of normal usage.
