Ways to access corrupted NSS VHD?

I have a virutal server in Hyper-V which was recently rebooted and on reboot it was pretty obvious that there was something wrong with the NSS hard drive. The server would boot up but after a few minutes it would freeze up and Hyper-V would no longer display the server's IP address in the Server's Network information tab.

Come to find out with some troubleshooting, once the NSS services started up the server's problems would begin. I tested this theory by disabling the storage VHD and the server came up and stayed up without any issue. I then created a new VHD, reattached it to OES and restored the data from backup.

Now I'm finding out that there were a couple of folders important folders that were not a part of the system's backup. I inherited this system and it has pretty much been a piecemeal system when it comes to learning how the previous person set things up. So now I'm looking for a way to try to reconnect tot he original VHD that seems to make the server want to crash so I can copy a couple of directories over to the new VHD. Does anyone have any good suggestions for accomplishing this if it is possible?

You can for instance install a new temporary OES server and attach the
VHD to that. When the temp box is in the same tree, you even get all the
trustees with you.

Oh, and of course you could/should run a poolrebuild on the drive.

I gave that a try and it doesn't work. As soon as the NSS service starts up the server seizes up. I found this out by getting a Putty session working to monitor the startup log and as soon as NSS starts the server locks up. I even tried to disable NSS in that brief window and haven't been successful.

- detach the vdisk
- clone it
- boot the box and
- add /poolautodeactivate=all to /etc/opt/novell/nss/nssstart.cfg
- down the box, reattach the vdisk, boot
- try a rebuild

while i'd rather doubt that you'll be able to recover stuff it's still worth a try...
If you like it: like it.
