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.
