Problem Description
|
|
What is the proper procedure for performing a root (/) filesystem
only restore through RecoverEDGE 2?
|
|
Cause
|
If the boot diskettes were created on a system on which
OpenServer 5 was installed via the "fresh install method", then
two filesystems must be restored: root (/) and boot
(/boot).
The real 'boot' and 'unix' programs are stored in the boot
filesystem whereas the symbolic links to these programs are stored
in the root filesystem. One must restore both filesystems or the
operating system will be unbootable after restore.
If the boot diskettes were created on a system on which
OpenServer 5 was installed via the "upgrade" method, then there
is no boot filesystem to be restored; the 'boot' and 'unix' programs
reside in the root filesystem.

Solution
|
|
To restore the root and boot (if appropriate) filesystems through
the RecoverEDGE 2 menu, perform the following:
1. Invoke Utilities->Editor
2. Load the file RE2.MOUNTLIST. This file contains a list of
the filesystems to be mounted during restore. Remove any
entries that pertain to filesystems OTHER THAN root (/) or
boot (/boot) and save these changes.
3. Load the file RE2.EXCLIST. This file contains a listing of
the directories which will be excluded during restore. Add
an entry for any directories that would reside outside of
the root or boot filesystems.
4. For example, if filesystems exist on the system called /u
and /u2, it would be necessary to exclude the /u and /u2
directories on tape from being restored, because the
corresponding filesystems are not mounted.
To do so, edit the file and add the following lines:
Exclude /u
Exclude /u2
After saving the changes to the file, perform Restore->
Restore All Filesystems -> and then continue with the restore
operation as specified in the manual.
If no /boot filesystem should be created, then performing a
root-only restore without any of the above steps would also work.
