Both failed totally after about 1-2 days of using them. Dmesg reported corruption errors/warnings. When I unmounted and tried to remount - mound was unable to find superblocks. Fsck for JFS was hopeless. Fsck for ReiserFS had to recreate superblocks, journal and rebuild tree (I am doing that now). So both FS where very badly corrupted. On both boxes I have other HDs with multiple filesystems (including JFS and reiserfs) and all is working fine for over year (including long time for 2.6.18 line). Before both failures I was playing with swap (swapoff -a swapon -a), I use encripted swap. The "old" partitions seem to be 100% ok all the time. It probably is not a hardware problem (I runned some low-level tests). So, perhaps there is a bug connected to some of the following aspects: - using newly or recently created file system (bug in code that is used to grow a short, "young" tree) - problems with swap / encrypted swap I saved image of 100 mb of the beginning of reiserfs partition after it failed, I can sent it (or part of it) if anyone wants to investigate.
