Kernel Messages
This section lists the VxFS kernel error messages in numerical order.
The Explanation sub-section for each message describes the problem,
the Action sub-section suggests possible solutions.
Each section lists the text of the message. In some cases, several variants
of the same message are listed separately. In some cases, variants are
shown together with a pipe symbol (|) separating the words that vary
(for example, read|write means that themessage will includeeither the
word read or the word write). Text in italic font indicates text that
will be replaced with a specific value in the message.
Global Message IDs
Each time a VxFS kernel message is displayed on the system console, it
is displayed along with a monatomically increasing message ID, shown
in the msgcnt field. This ID guarantees that the sequence of events is
known in order to help analyze file system problems.
Each message is also written to an internal kernel buffer and can be
viewed in the file /var/adm/syslog/syslog.log .
In some cases, additional data is written to the kernel buffer. For
example, if an inode is marked bad, the contents of the bad inode are
written. When an error message is displayed on the console, you can use
the unique message ID to find the message in
/var/adm/syslog/syslog.log and obtain the additional information.

• Explanation
The file system is out of space.
Often, there is plenty of space and one runaway process used up all
the remaining free space. In other cases, the available free space
becomes fragmented and unusable for some files.
• Action
Monitor the free space in the file system and prevent it from
