    SubjectEXT2-fs warning (device 16:0n)...
    Date
    Hi all,

    I'm happily running Debian 1.1 with Kernel 2.0.10 on several different
    machines here, but last week one of these began to show these messages (after
    a crash due to a power failure):

    EXT2-fs warning (device 16:01): ext2_free_inode: bit already cleared for inode 24481
    EXT2-fs warning (device 16:01): ext2_free_inode: bit already cleared for inode 24481
    [...]
    EXT2-fs warning (device 16:02): ext2_free_inode: bit already cleared for inode 136220
    EXT2-fs warning (device 16:01): ext2_free_inode: bit already cleared for inode 24481
    EXT2-fs warning (device 16:02): ext2_free_inode: bit already cleared for inode 136217
    EXT2-fs warning (device 16:02): ext2_free_inode: bit already cleared for inode 136218
    EXT2-fs warning (device 16:02): ext2_free_inode: bit already cleared for inode 136219
    [....]

    The PC is a Pentium 100, 32 MB Ram and the hard disk setup is this (from dmesg):

    ide: i82371 PIIX (Triton) on PCI bus 0 function 57
    ide0: BM-DMA at 0x3000-0x3007
    ide0 timing: (0xa307) sample_CLKs=3, recovery_CLKs=1
    master: fastDMA=on PreFetch=on IORDY=on fastPIO=on
    slave : fastDMA=off PreFetch=off IORDY=off fastPIO=off
    ide1: BM-DMA at 0x3008-0x300f
    ide1 timing: (0xa307) sample_CLKs=3, recovery_CLKs=1
    master: fastDMA=on PreFetch=on IORDY=on fastPIO=on
    slave : fastDMA=off PreFetch=off IORDY=off fastPIO=off
    hda: Conner Peripherals 1275MB - CFS1276A, 1221MB w/0kB Cache, LBA, CHS=2482/16/63
    hdc: Conner Peripherals 1275MB - CFS1276A, 1221MB w/0kB Cache, LBA, CHS=2482/16/63
    hdd: OTI-SCYLLA, ATAPI CDROM drive

    The first question is this: which device are 16:02 and 16:01 ? I looked in /dev
    searching for devices whith major number 16 but I didn't found any.
    Shouldn't hda and hdc correspond to major 3 and 22 ?

    The disks are so partitioned:

    Filesystem 1024-blocks Used Available Capacity Mounted on
    /dev/hda1 31687 8721 21330 29% /
    /dev/hda3 63439 37 60126 0% /tmp
    /dev/hda5 495714 232237 237876 49% /usr
    /dev/hda6 297603 41177 241056 15% /var
    /dev/hda7 227349 22334 193274 10% /usr/local
    /dev/hdc1 495714 146812 323301 31% /web
    /dev/hdc2 715203 21411 656849 3% /home

    I've tryed to e2fsck /dev/hdc2 (thinking that device 16:02 corresponds
    to /dev/hdc2) and it found a lot of errors, but it seemed that e2fsck
    was able to correct them all; after rebooting similar messages appeared
    again after some hours.

    Any clue about this?

    Tahnks in advance and best regards,
    Luca.
