Message: 055
WARNING: msgcnt x: vxfs: mesg 055: vx_metaioerr - file system meta data error
Explanation:
A read or a write error occurred while accessing file system metadata. The full fsck flag on the
file system was set. The message specifies whether the disk I/O that failed was a read or a write.
File system metadata includes inodes, directory blocks, and the file system log. If the error was a
write error, it is likely that some data was lost. This message should be accompanied by another
file system message describing the particular file system metadata affected, as well as a message
from the disk driver containing information about 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. Unmount the file system and use fsck to run a full structural check (possibly
with loss of data). In case of an actual disk error, if it was a read error and the disk driver remaps
bad sectors on write, it may be fixed when fsck is run 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: 056
WARNING: msgcnt x: vxfs: mesg 056: vx_dataioerr - file system file data 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 should be accompanied by a message from the disk driver containing information about
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.
