Input/output error

Input/output error

[Marcus Grando]

Hi list,

After reboot in kernel 2.4.15-pre9 this problem occur:

On try start syslog deamon occur this errrors "Input/output error" on many archives /var directory.

I mount the /var at boot linux single, and when try ls on /var/run list all archives .pid, 
before try ls -la on /var/run, not list all archives.
Try remove .pid archives and the error occur again.

/var partition use ext2

Any suggestion?

Tanks in advance,

Regards
Marcus Grando

Try to run fsck on the /var partition. Also you should check the disk 
for bad blocks. What output do you get from the kernel ('dmesg', 
/var/log/messages etc.)?

It could be a bad disk developing bad sectors.

On my machine (2.4.15 final) it is the same behaviour.  After reboot
the lock files (and only the lock files) are corrupt. With 2.4.14 and 
2.4.13 everything works fine. gcc 2.96, e2fsck 1.25, aic7896/97

e2fsck output:

I take it that this is after a normal shutdown where you are sure that
the filesystem was unmounted cleanly?  It looks like a case where these
files are deleted, but held open by a process.

Could you please try the following:
- "telinit 1" to change into single user mode
- make sure all of the above processes are stopped (check via ps, and
  "/etc/rc.d/init.d/foo stop" for each one
- "lsof | grep /var" to see if any files are still open on /var
- umount /var
- e2fsck -f /dev/hdX

Cheers, Andreas

	Hello,

	I have this problem too, i execute fsck more 20 times and not 
resolv this problem.

	Execute badblocks(8) and not found bad blocks

	I note before linux-2.4.15-pre8 begin this problems.

	Changelog-pre8:
	 - Andrew Morton: fix ext3/minix/sysv fsync behaviour.

	Maybe? I don´t no.

Regards,

Marcus Grando

A "me too" here (2.4.15 final) -- ran fsck on the /var partition and saw 
output similar to that below.

It's a normal shutdown, every filesystem is unmounted cleanly, no
complains from the os.

There are a few processes running: news, something called minilgd.Even 
with these programs running lsof shows no output. If I kill these 
programs and make a normal shutdown, it loocked much better. Only a 
complain about the keyboard lock.

If I acted exactly like your advise, there is no problem with the restart.

The processes running in 2.4.15 single user mode are exactly the same as 
in 2.4.14.

This is the FS bug that Al Viro has fixed for 2.4.15/2.5.0.
