Created from <SR 3-4453871381>

Applies to:

Exadata Database Machine X2-2 Hardware - Version: Not Applicable and later [Release: N/A and later ]
Linux OS - Version: Oracle Linux 5.3 to Oracle Linux 5.5 [Release: OL5U3 to OL5U5]
Linux x86-64

Symptoms

Compute Node message log says:
logrotate: ALERT exited abnormally with [1]
kernel: scsi 8:0:0:0: rejecting I/O to dead device
kernel: scsi 8:0:0:0: rejecting I/O to dead device
kernel: FAT: Directory bread(block 30640) failed
kernel: scsi 8:0:0:0: rejecting I/O to dead device

Cause

Someone has been removing a USB memory “thumb drive” without unmounting it first

Solution

On a Compute Node, “eject” is located as /usr/sbin/eject.
By default, this is in the PATH for the root account.
It is provided from the eject-2.1.5-4.2.el5 package

On a Storage Cell, that RPM is not installed by default. That just means that you will have to use umount /media/disk command instead
