Patch Name:  PHKL_4858

Patch Description: s700 9.0[357] panic in quotactl() on diskless clients

        Diskless systems panic with "Data segmentation fault" in quotactl()
        system call when a client has a locally mounted file system with
        quotas enabled.  For more details, see 1653106526.

        This patch fixes the problem where diskless machines can crash if at
        least one of the clients has a locally mounted file system with quotas
        enabled.

        This problem will only occur if the client with the locally mounted
        file system has crashed, been powered off or rebooted with the "-q"
        option.  Any other machine of the cluster (including the server) can
        then crash at a later time. Strange things can happen including
        incorrect values in the disk quota entries.

        The fix consists of cleaning up disk quota entries for a file system
        that was on a diskless client that crashed. The fix also cleans up the

        mount table entries that are from the crashed site.

        This patch is required on all diskless systems where quotas are
        enabled on the client's locally mounted file system.

After getting the patch onto your machine, unshar the patch (sh PHKL_4858).

To install this patch do the following:
1) Run /etc/update (Note: you must be logged in as root to update
   a system).
2) Once in the update "Main Menu" move the highlighted line to "Change
   Source or Destination ->" and press "Return" or "Select Item".
3) Make sure the highlighted item in the "Change Source or Destination"
   window is "From Tape Device to Local System ...", then press "Return" or
   "Select Item".
4) You should now be in the "From Tape Device to Local System" window.
   Change the "Source:  /dev/rmt/0m" to "Source: /tmp/PHKL_4858.updt"
   (this assumes that you are in the /tmp directory where PHKL_4858.updt
   has been placed).  Note: You must enter the complete path name.
5) Press "Done".

The customized script that update runs will move the original software

order to recover from any potential problems.  It is also recommended that
you move the PHKL_4858.text file to /system/PHKL_4858 to be retained for
future reference.

If you wish to put this patch on a magnetic tape and update from the tape
drive, dd a copy of the patch to the tape drive.  As an example the
following will create a copy of the patch that update can read:
dd if=PHKL_4858.updt of=/dev/rmt/0m bs=2048
