Soloaris 8/ufsdump error
I'm running a process to tape that periodically gives an error similar to the following
DUMP: bread: dev_seek error: Error 0
DUMP: Warning - block 1126006886 is beyond the end of `/dev/rdsk/c2t5d0s6'
Note: I get multiple messages like this where the block number changes.
The device listed is my Raid 5 disk array and it has more than enough space available
Filesystem 1k-blocks Used Available ev/dsk/c2t5d0s6 104936048 37613567 66273121
Use% Mounted on
37% /usr/local
Any thoughts as to what is causing this condition and how I might go about fixing it?

NAME
cmdk - common disk driver
SYNOPSIS
cmdk@target, lun : [ partition | slice ]
DESCRIPTION
The cmdk device driver is a common interface to various disk devices. The driver supports magnetic fixed disks and magnetic removable
disks.
The block-files access the disk using the system's normal buffering mechanism and are read and written without regard to physical disk
records. There is also a "raw" interface that provides for direct transmission between the disk and the user's read or write buffer. A sin-
gle read or write call usually results in one I/O operation; raw I/O is therefore considerably more efficient when many bytes are transmit-
ted. The names of the block files are found in /dev/dsk; the names of the raw files are found in /dev/rdsk.
I/O requests to the magnetic disk must have an offset and transfer length that is a multiple of 512 bytes or the driver returns an EINVAL
error.
Slice 0 is normally used for the root file system on a disk, slice 1 as a paging area (for example, swap), and slice 2 for backing up the
entire fdisk partition for Solaris software. Other slices may be used for usr file systems or system reserved area.
Fdisk partition 0 is to access the entire disk and is generally used by the fdisk(1M) program.
FILES
