RE: Input/output error

	I just start experiencing the exact same problems on one of my
RedHat 7.3 servers.  So far it has been about once a week.  The first
time this happened, I was lucky enough to get an error in the error log,
and it turned out to be from an old kernel bug (kernel BUG at
journal.c:406!)  I upgraded from 2.4.18-3smp to 2.4.18-27.7.xsmp, but
the problem came back, this time with no errors in the log.

I thought it might be hardware related (the system would not boot with
hda in the system after the 1st crash), so I replaced a harddrive,
rebuilt the array, ran e2fsck on /dev/md*, and so far, everything has
been fine. It has only been 3 days though, I am afraid the problem might
come back.

I don't know if any of this helps, but I would like to get to the bottom
of this too.

I'm running:

RH 7.3
with ext3
the rh kernel 2.4.18-27.7.xsmp
And raid 1 on dual WDC 120 GB harddrives.

/dev/md0              4.8G  1.1G  3.4G  24% /
/dev/md2               45M   19M   24M  43% /boot
/dev/md1               99G  8.0G   86G   9% /home
none                 1008M     0 1008M   0% /dev/shm
/dev/md3              4.8G  464M  4.1G  10% /var

Hi All,

About once a week, I get a this strange error on bash command line.
Running any command on the command line results in " Input/output
error". Only way to get back to normal operation is to hard reboot the
machine. I suspect this is something to do with my file system. I am
using RH7.3 with ext3 file system on IBM Travelstar drives. 

I use dd to duplicate the drives. The source and the target drives are
identical (same make, model) .I am not sure, but I suspect this error
message comes up only on the duplicated drives. (I have never seen this
message on my desktop which has  a different drive). 

Any pointers on what is causing this problem would be great
