Failed in upgrade

[Jimilu]

i am trying to upgrade my tivo drive for the seciond time and i having some problems using hinsdale. I am trying to preserve even my recordings froma a 11o bg drive to a 250 gb drive.
this is what i get at the last step
mfsbackup -Tao - dev/hdc | mfsrestore -s 127 -xapi - dev/hda
Scanning source drive. Please wait a moment.
Source drive is 40 hours
- Upgraded to 126 hours
Uncompressed backup size 103044 megaytes.
Restore failed: Backup target notlarge enough for entire backup by itself.

or if y try this
mfsadd -x /dev/hdc
i get estimated standalone size 126 hours
Nothing to add


I already did this:
dd if=/dev/hdc of=/dev/hdb bs=1024k

and the new drive worked, but the recorder capacity stayed the same as before, so i began again using mfstools, and failed.

have i missed something?

someone smarter than me can feel free to correct me, but I don't think you can expand twice. Your command told you that is what's going on here. a 40 hr upgraded to 126.
There MIGHT be a way to do it, but since I've never needed to I haven't investigated.

Under certain conditions it is posible to merge two mfs partitions into a single one. It's not for the faint of heart, and results in a drive that cannot be backed up using mfstools. Instructions here (http://alt.org/forum/index.php?t=msg&goto=769&rid=0&S=7685e15b700295296be568c78ad27ee8#msg_769).

Thanks fot the help, but i think i would backup manually and expand from the 40 gn directly to 250..
I do not know what a pearls scrit is.

Consider ADDING the 250Gig drive. You'd probably want to buy a specially made bracket to mount the new additional drive but they're cheap, or you could probably rig up a bracket of your own design if your really cheap or impatient.

But, you could just add the 250Gig drive in a snap with the command

mfsadd -x -r 3 /dev/hdc /dev/hda

The command will take like literally 2 seconds. Mount both drives back in your Tivo and your done. You've still got all your recordings and you've got the combined capacity of your current 120Gig plus the 250Gig, I don't know what that would work out to exactly but it'd be around 400 hours.

If you made a 127 Meg swap on your first upgrade, and I'm guessing you did, then I believe you'll be fine adding the 250Gig.

I was in a similiar situation recently, replaced my 80 Gig B drive with a 400Gig. My A drive had already been expanded once and I wanted to keep all the recordings so I couldn't redo it and expand the swap. I've currently got 120Gig A, 400Gig B, 127Mb swap and if I force a Green Screen of Death it'll successfully complete in about 10 minutes.

If you just have a default size swap partition and want to add a 250Gig drive, hmm I don't know, ask what the other people on here think.
