Post Restore of A Drive "?"
(Click here to view the original thread with full colors/images)

Posted by: VoR

Restored my backup onto my "A" drive last night and everything booted up fine etc (sans the call in to restore TiVo service and guide data).

But it is not seeing the extra space of the B drive. Do I need to take it out and Bless it again? or Reformat and Bless?
or ?

Thanks

You need to use MFS Tools 2.0's mfsadd function (see New Hinsdale) to expand your image.

Compressed, or 'divorced', backups only take the partitions from the /original/ A drive, reversing any upgrades. Therefore, as you've discovered, when you restore a backup you come back to your original system.

mfsadd (or using MFS Tools 2.0 mfsrestore with -x) will expand your image into any unused space on either drive. It results in a faster TiVo than TiVoMad/BlessTiVo and seems to be safer too.

Does this sound like what I should do then?

Pull my 'A' drive again and make a new backup using MFS Tools 2.0

Restore the backup onto my 'B' Drive and place it into the TiVo to ensure a good backup was made.

Restore the backup onto my 'A' drive using the (-s 127) to increase the swap. :confused: (this step I am assuming and am really not sure it is necessary, if it speeds things up I am all for it)

Then place both drives into PC ('A' as Secondary Master, 'B' as Primary Slave) and run:

mfsadd -x /dev/hdc /dev/hdb

Place drives back into TiVo and be back in 108*hr DTiVo Bliss?

Extra swap doesn't make your TiVo any faster, but it does help really large TiVoes recover from the green screen of death. DTiVoes can cope up to 180Gb without extra swap.

Increasing swap now would make it easier to upgrade further while keeping your recordings.

Thanks for the help Robert!

I'll go ahead and do it now to make things simple.

I now want to make a new backup of my drives. Since I have added the 'B' drive any backups will have to be made with both drives connected correct? Not just the 'A' drive right?

Also the backup can be named tivo2.bak right? So I don't overright my previous backup file.

Yes, MFS Tools requires both backups of a twin to make a backup, even though very little data will be read off the B drive if you're making a compressed backup.

The name of the backup isn't important. As long as the string after the -o in the mfsbackup command points to a valid filename it can be anything you like.

Welp it was too good to be true. After going a week or two up the thing came to rebooting loop. Restored the B drive as just a single Drive A to see if the A was bad, lasted about 24 hours before reboot looping. Stuck in a 3rd drive (80GB Maxtor I am adding to parents TiVo) by itself and all I get is "Welcome. Powering Up..."

Restored Original A drive once more and get the same but it loops. Also tried another IDE cable and reinstalling the white power ribbon cable.

My guess is PS is shot?

~bump~

Anyone confirm that the culprit is likely the PS before I send my TiVo away for a month?
