022 WARNING: msgcnt x : vxfs: mesg 022: vx_mountroot - root file system remount failed
• Description
The remount of the root file system failed. The system will not be usable if the root file
system can’t be remounted for read/write access.
When a VERITAS root file system is first mounted, it is mounted for read-only access.
After fsck is run, the file system is remounted for read/write access. The remount fails if
fsck completed a resize operation or modified a file that was opened before the fsck was
run. It also fails if an I/O error occurred during the remount.
Usually, the system halts or reboots automatically.
• Action
Reboot the system. The system either remounts the root cleanly or runs a full structural
fsck and remounts cleanly. If the remount succeeds, no further action is necessary.
Check the console log for I/O errors. If the disk has failed, replace it before the file system
is mounted for write access.
If the system won’t come up and a full structural fsck hasn’t been run, reboot the system
on a backup root and manually run a full structural fsck. If the problem persists after the
full structural fsck and there are no I/O errors, contact your customer support
organization.
023 WARNING: msgcnt x : vxfs: mesg 023: vx_unmountroot - root file system is busy and can’t
be unmounted cleanly
• Description
There were active files in the file system and they caused the unmount to fail.
When the system is halted, the root file system is unmounted. This happens occasionally
when a process is hung and it can’t be killed before unmounting the root.
• Action
fsck will run when the system is rebooted. It should clean up the file system. No other
action is necessary.
If the problem occurs every time the system is halted, determine the cause and contact
your customer support organization.
