069 WARNING: msgcnt
x
: vxfs: mesg 069: memory usage specified by the vxfs:vxfs_ninode and
vxfs:vx_bc_bufhwm parameters exceeds available memory; the system may hang under
heavy load
Description
The value of the system tunable parameters—vx_ninode and vx_bc_bufhwm—add up to a
value that is more than 66% of the kernel virtual address space or more than 50% of the
physical system memory. VxFS inodes require approximately one kilobyte each, so both
values can be treated as if they are in units of one kilobyte.
Action
To avoid a system hang, reduce the value of one or both parameters to less than 50% of
physical memory or to 66% of kernel virtual memory. For more information on
performance and tuning, see “VxFS Performance: Creating, Mounting, and Tuning File
Systems” on page 29. Note: The tunable parameter vx_ninode is used to set the value of
vxfs_ninode.

: vxfs: mesg 071: cleared data I/O error flag in
mount_point
file system
Description
The user data I/O error flag was reset when the file system was mounted. This message
indicates that a read or write error occurred (see Message Number 38) while the file
system was previously mounted.
Action
Informational only, no action required.

fileset (index
number
) fileset header checksum bad
Description
An incorrect fileset header checksum was found while adding a new inode allocation unit.
The VX_FULLFSCK flag is set and the file system is disabled to preserve integrity. This
message is typically generated after a message 003 or message 004 (see Message Number
003, 004, 005).
Action
Check the console log for I/O errors. If the problem is a disk failure, replace the disk,
otherwise save a metadata image and contact your customer support organization. Use
fsck to run a full structural check before remounting the file system.
