• Description
When inode information is no longer dependable, the kernel marks it bad on disk. The
most common reason for marking an inode bad is a disk I/O failure. If there is an I/O
failure in the inode list, on a directory block, or an indirect address extent, the integrity of
the data in the inode, or the data the kernel tried to write to the inode list, is questionable.
In these cases, the disk driver prints an error message and one or more inodes are marked
bad.
The kernel also marks an inode bad if it finds a bad extent address, invalid inode fields, or
corruption in directory data blocks during a validation check. A validation check failure
indicates the file system has been corrupted. This usually occurs because a user or process
has written directly to the device or used fsdb to change the file system.
The VX_FULLFSCK flag is set in the super-block so fsck will do a full structural check the
next time it is run.
•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 is writing to the device, report the problem to your customer support
organization. In either case, unmount the file system and use fsck to run a full structural
check.
080 WARNING: msgcnt
x : vxfs: mesg 080: Disk layout versions older than Version 4 will not
be supported in the next release. It is advisable to upgrade to the latest disk layout version
now. See vxupgrade (1M) for information on upgrading a VxFS file system and see the
VxFS Release Notes for information on disk layout support.
•Action
Use the vxupgrade command to begin upgrading file systems using older disk layouts to
Version 4. Consider the following when planning disk layout upgrades:
• Version 2 disk layout file systems have an 8 million inode limit.
• Images of Version 2 disk layout file systems created by copy utilities, such as dd or
volcopy, will become unusable after a disk layout upgrade. Offline conversions tools
will be provided in the next VxFS feature release to aid in migrating volume-image
backup copies of Version 2 disk layout file systems to a Version 4 disk layout.
