since fsck is likely to rewrite the sector with the read error. In other
cases, you replace or reformat the disk drive and restore the file
system from backups. Consult the documentation specific to your
system for information on how to recover from disk errors. The disk
driver should have printed a message that may provide more
information.
Message 038 WARNING: msgcnt

file system file data read|write error
Explanation
A read or a write error occurred while accessing file data. The
message specifies whether the disk I/O that failed was a read or a
write. File data includes data currently in files and free blocks. If the
message is printed because of a read or write error to a file, another
message that includes the inode number of the file will print. The
message may be printed as the result of a read or write error to a free
block, since some operations allocate an extent and immediately
perform I/O to it. If the I/O fails, the extent is freed and the operation
fails. The message is accompanied by a message from the disk driver
regarding the disk I/O error.
Action
Resolve the condition causing the disk error. If the error was the
result of a temporary condition (such as accidentally turning off a
disk or a loose cable), correct the condition. Check for loose cables, etc.
If any file data was lost, restore the files from backups. Determine the
file names from the inode number (see ncheck_vxfs(1M) for more
information.)
If an actual disk error occurred, make a backup of the file system,
replace or reformat the disk drive, and restore the file system from
the backup. Consult the documentation specific to your system for
information on how to recover from disk errors. The disk driver
should have printed a message that may provide more information.

file system super-block write error
Explanation
An attempt to write the file system super block failed due to a disk
I/O error. If the file system was being mounted at the time, the mount
will fail. If the file system was mounted at the time and the full fsck
