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.
