5.0.6a supplements were installed successfully. I am trying to find out exactly what directories are on my backup. I have ran a verify/list function from the edgemenu, and it appears there are no problems with my tape. I did not sit and watch every file name as it was being verified, thinking I would get to see a list afterward - but I can't find the list to check. I know there are the following: /u, /usr, /lost+found, /etc, and more. As they scroll through all of the listings are prefaced with a ./ - is that normal? When I get ready to restore and enter my list of directories, will I use the . before the /? Is it worth the time to hook up the old hard drive just long enough to get the directory names under the / directory? I feel like I'm almost there, I just don't want to do anything wrong with the restore to undo my work so far. Thanks!

There should be a copy of the file listing in /usr/lib/edge/lists/menu
You may have to also check /usr/lib/edge/lists/simple_job.
If you restored everything excep /etc/conf, then you should have everything that was on the old hard drive.
What may be different is that /u, for instance, might have been a file system on the old system, but is now just a directory in the root file system.

I did a full backup of the system after my reinstall, before doing the Restore from my tape. I had to clean the heads of my tape drive, luckily I still had a cleaning tape and it worked. I restored everything except /etc/conf and the job completed "with exceptions" - but I don't know what they were or if important.

The one problem is that /u is a File System, I know this for a fact, but I don't remember what type of File System. After the restore and reboot, it looks like it tried and failed to mount the /u filesystem - it just said "failed to mount". I know this is where most of the inner workings of my legacy application live, so can you tell me what steps to take in order to try and remount this /u file system?

Thanks - you have been VERY helpful and I appreciate it.

Been reading up a little, it looks like I need to run divvy to create the u division on the disk. Old system had root from 539648 - 10000025, and u from 10000026 - 38973679 (40 GB hard drive)

Current system shows root from 539648 -134070446 (140 GB hard drive) I think divvy will let me create the u division and I can probably figure a size. If this is the correct action, should I first delete everything I "restored" to the /u directory? Then would I create and mount the file system, and do a new restore of the /u on the backup tape?

Let me know if I am on the right track, or what else to do. Thanks again.

The boot file system is EAFS, the root and any other (/u) file systems default to HTFS.
You cannot re-size an HTFS partition without losing the data that is on it. So you will not be able to add the /u file system without doing a full backup and standalone restore.
From an operational point of view, it will make no difference if /u is a file system, or simply another directory in the root file system.
If you must, do a full backup, boot from the Edge recovery media, re-size the partitions, and do full restore.

I now what happened. When you restored the old data, you restored /etc/default/filesys, which has the file system configuration. Unfortunately the one that has been restored contains info on /u but that file system no longer exists.
Just use a text editor and remove the references to /u.
