jfs and xfs - experience anybody?
Due to fragmentation problems with my data partition on a ext3 filesystem I looked around a bit and it seems either xfs or jfs are the way to go.Does anybody have experience with those? I do have frequent power losses.

No experience, but I'm wading through some articles by Daniel Robbins, President/CEO of Gentoo that might help. He has written a series that are on IBM's Linux website. Go to this address:

Scroll down to the articles labeled "Common Threads: Advanced filesystems implementator's guide." These articles cover everything from ext2 to Reiserfs to xfs. Along the way there are explanations of VMS and devfs.

JFS is mentioned in Part 7 and there is a link for a tutorial. Since JFS is an IBM idea and this is an IBM website, a simple search on the subject should turn up much more.

XFS starts in Part 9 and continues through Part 11.

The only irritant to these outstanding articles is they were written over a period of time and don't always link to each other--when you finish with Part 3, there is no link to go to Part 4! Other than that, they are outstanding articles.

Good luck

Thanks - I'll check that out.Meanwhile,after some searches on the gentoo forums,it seems like there is a fair number of people that had file system corruption issues with xfs.

As I understand it, xfs is still in the experimental stages and not the stable ones. Daniel Robbins articles still left me with the impression that he sees a promising future for it

xfs sounds pretty good in various aspects - especially to handle big files.I'll probably put jfs on a partition and xfs on another one and see what happens.I did like reiserfs and ext3 but with ext3 you got to convert to ext2 to defrag and with reiserfs there are no tools to do that at all AFAIK.jfs has a defrag tool and with xfs it 'shouldn't be a problem with big files'.I got me the 2.4.20 tarball with jfs support and throw that in - see how it goes.
