Do you happen to remember about which kernel that was? There was some general badness that affected multiple file systems in late 2.6.13 on into 2.6.14 or so in the way that you describe. Not sure they ever really knew what the smoking gun was. Used JFS for about 6 months with the gentoo mips 2.6.13 kernel and did not find any issues. Briefly with Sparc32, but don't remember which kernel. On Intel, I've done extensive regressions with it. If anyone is interested, I have a thrasher script written specifically for this purpose. It's a multi-threaded ruby script that creates a randomized directory tree, with random files, containing random data. A CRC check is kept on each file. The threads run in parallel rewriting data in the middle of files, truncating, resizing, creating voids, forcing the file system into writing multiple extents, exercising tail packing, unlinking files with open handles, etc... -S- On Fri, 9 Feb 2007, Alex Deucher wrote: > On 2/9/07, J.
