I have XFS on my freevo system for the data partition. I do this bacause all data here is rarely writen, and if recordings crash, the file itself is still partially playable. However XFS has great performance for large files, which is perfect for movies and stuff, and kan delete an entire DVD in few seconds. Secondly I use LVM underlying, so its easy ability to increase partition size makes it usefull for stuffing more disks into the system while having only a single data partition.Op vr 07-01-2005, om 17:33 schreef Eric Jorgensen:
Where? I can't find it. Several pages on gentoo.org actually point to
it's default support of xfs as one of the reasons it's better than

When you read the manual the "preparing the disks" section: http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=4 chapter "4.d. Creating Filesystems" quote: XFS is a filesystem with metadata journaling which comes with a robust feature-set and is optimized for scalability. We only recommend using this filesystem on Linux systems with high-end SCSI and/or fibre channel storage and an uninterruptible power supply. Because XFS aggressively caches in-transit data in RAM, improperly designed programs (those that don't take proper precautions when writing files to disk and there are quite a few of them) can lose a good deal of data if the system goes down unexpectedly.
My XFS system has had unexpected lockups (caused by intermittently
flaky hardware) and power failures about a half a dozen times now, and I've
experienced no data corruption.
I have it on all my machines, and had data corruption at every power fail at every machine. Some minor some not minor and unrecoverable. Hardware seem to have something to do with it, on my server the OS is on scsi and that's the only drive that (as far as I now) didn't had data loss. I have 2 24/7 machines (one is the freevo/ftp machine) with 2.4 kernel and a workstation with 2.6, the last one seem to have less irrecoverable errors. (meaning xfs_repair does the trick)
Don't use it on a critical machine!
Reiserfs ofcourse has even better control over the size, however its optimized for small files, and therefore less ideal than XFS.
On the root partition however I use ext3, which IMHO is the best all-round system available. Fairly fast, somewhat resizeable, journaled, but also journals data and is much less prone to corruption than XFS/ReiserFS. Its fully compatible ext2, which allows for easy datarecovery and repairs. Also ext3 can be switched into a non-complete journaled mode (writeback) which doubles its speed (just about) but leaves the corruption problem.
Usually I use ext3 for everything, but XFS actually impresses me with speed when deleting/moving large files, otherwise its comparable to ext3(writeback).
