038 WARNING: msgcnt x: mesg 038: V-2-38: vx_dataioerr - file system file
data error
• Description
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 the ncheck(1M) manual page 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.
