    Basically, I'm using NFS and reiserfs. But I didn't use any file on NFS
    since the last reboot - and the NFS-shares haven't been mounted.

    There are 2 IDE-Harddisks in this machine:
    hda: WDC WD205AA, ATA DISK drive (40079088 sectors (20520 MB) w/2048KiB
    cache, CHS=2494/255/63, UDMA(66))
    hdb: WDC WD450AA-00BAA0, ATA DISK drive (87930864 sectors (45021 MB)
    w/2048KiB Cache,
    CHS=5473/255/63, UDMA(66))

    On hda, I have got 7 partitions (plus one little "boot"-partition, which
    isn't mounted and a 200MB swap partition).
    On hdb, I have got 12 partitions and one more, meanwhile 1GB swap partition.
    All partitions are formated with reiserfs.
