002 WARNING: msgcnt x: vxfs: mesg 002: vx_snap_strategy - mount_point file system write
attempt to read-only file system
WARNING: msgcnt x: vxfs: mesg 002: vx_snap_copyblk - mount_point file system write
attempt to read-only file system
• Description
The kernel tried to write to a read-only file system. This is an unlikely problem, but if it
occurs, the file system is disabled.
• Action
The file system was not written, so no action is required. Report this as a bug to your
customer support organization.

WARNING: msgcnt x: vxfs: mesg 003: vx_mapbad - mount_point file system free extent
bitmap in au aun marked bad
WARNING: msgcnt x: vxfs: mesg 004: vx_mapbad - mount_point file system free inode
bitmap in au aun marked bad
WARNING: msgcnt x: vxfs: mesg 005: vx_mapbad - mount_point file system inode
extended operation bitmap in au aun marked bad
• Description
If there is an I/O failure while writing a bitmap, the map is marked bad. The kernel
considers the maps to be invalid, so does not do any more resource allocation from maps.
This situation can cause the file system to report out of space or out of inode error
messages even though df may report an adequate amount of free space.
This error may also occur due to bitmap inconsistencies. If a bitmap fails a consistency
check, or blocks are freed that are already free in the bitmap, the file system has been
corrupted. This may have occurred because a user or process wrote directly to the device or
used fsdb to change the file system.
The VX_FULLFSCK flag is set. If the map that failed was a free extent bitmap, and the
VX_FULLFSCK flag can’t be set, then the file system is disabled.
• Action
Check the console log for I/O errors. If the problem is a disk failure, replace the disk. If the
problem is not related to an I/O failure, find out how the disk became corrupted. If no user
or process was writing to the device, report the problem to your customer support
organization. Unmount the file system and use fsck to run a full structural check.
