sets the VX_FULLFSCK flag and the mount fails.
If the error isn’t related to an I/O failure, this may have occurred
because a user or process has written directly to the device or used
fsdb to change the file system.
• 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.
Message 022 WARNING: msgcnt x : vxfs: mesg 022: vx_mountroot - root
file system remount failed
• Explanation
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 VxFS 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.
