lstat I/O error

[Ryo Furue]

Hello all,

On a Solaris 9 machine, I'm having an I/O error:

$ cd /some/directory
$ echo * | (fgrep -s ' msg00175.html '; echo $?)
0 #--> file does exist.
$ ls msg00175.html
msg00175.html: I/O error #--> cannot stat
$ truss ls msg00175.html
[...]
lstat64("msg00175.html", 0xFFBFFB50) Err#5 EIO
[...]
$

There's no related error message either in /var/log/syslog or
/var/adm/messages . The message "I/O error" isn't very helpful;
the message doesn't tell you what's wrong with the file.

I'm wondering how I can obtain more information about the
(apparently) broken file beyond "I/O error". The only fix
may be just to delete the file, but
1) I'm wondering if it's possible to recover the file, and
2) I'm curious.

Thank you,
Ryo

If it is a local disk ('df -F' tells it),
try to umount it and run fsck.
(otherwise 'reboot -- -s' then run fsck).

If it is on the network, umount/mount it.
