If fdisk -l sees no /dev/sdb5, I'm wondering what kind of problem you are suffering. What is the contents of /proc/partitions?

My Linux Box suffers the following I/O error. From the analysis above, I think the I/O error occurs at the 5th slice of the secondary scsi hard disk. I want to know how to fix the I/O error
--- fsck ?

Jul 18 04:03:20 sys52 kernel: Directory sread (sector 0x1f5) failed
Jul 18 04:03:20 sys52 kernel: I/O error: dev 08:21, sector 501

According to your system, /dev/sdb has no partitions, so the error with 08:21 is very odd. What is on the sdb disk?

Some Read failure to sdb.


I think the sdb can not be recognized by kernel.

I found sys52 just one SCSI disk connected. I stopped the cron job, then the dev I/O error disappeared.

Thank you.
