DvrBARS vs MFStools to minimize downtime (TCD758250)

Advertisements

Hello,

I think my drive is starting to go bad as it is 7 years old (original drive). I'm wanting to minimize downtime as I am working from home.

Can I use the DvrBARS tools to create an image on a 4tB drive (no recordings needed) while using MFStools to move to a 6tB drive with recordings? The 6tB drive will replace the original Tivo drive.

Thanks,
Gary

 

Let me clarify my question based on the above response.

GOAL - minimize Tivo downtime while getting to 6tB

In other words, I want to minimize the amount of time that I am without my Tivo.​

Which of the following options is faster? Time estimates?

1. Use DvrBARS to make an image on a 4tB drive(no recordings, no expansion)? Will be used temporarily while I image the 6tB drive using MFStools.
2. Use MFStools to go directly to the 6tB drive.​

Regards!

When I move to the 6tB drive, the source drive will be the original Tivo disk.
- In step 2 I would use the command, "mfsadd -xM 4000 /dev/sdY"?
- And then stop after step 4?

 

When I issued the "mfsadd -xM 4000 /dev/sda", I got the error, "Expand of /dev/sda would result in too many partitions." sda is the 6tB drive.

When I put the drive into the Tivo, everything works.
- I'm now showing 25% used rather than 52%.
- I was able to view the last show I recorded.

How do I fix the too many partitions error?

I have attached the output from "mfsinfo -d" for the 6tB drive. Here is the partition table. Please note that this is the first time upgrading this Premier XL4.

As I expected, I do not have 800+ hours. I have a recording capacity of 686 HD hours. This is what I expected since "My Shows" show 25% utilization. Had I expanded to the full 6tB, I would have expected "My Shows" to be somewhere around 12%. In my previous post I attached the output from a "mfsinfo -d".

Regards.

 

As I stated in my earlier post,

The "mfsadd" is step 2 of the 8tB note.

 

From the 8tB instructions.
1) mfscopy -aiM 4000 /dev/sdX /dev/sdY
2) mfsadd -xM 6000 /dev/sdY

In note #4, you said to use 4000 rather than 6000.
In note #5, I asked to confirm to use 4000 in the mfsadd command as you had not provided context.​

Step 2 is where I get the error.

Now, how do I fix this?

 

Sorry, I cut and pasted the mfsadd command straight from the 8tB instructions.

I did use 4000 because I wrote the instructions out.

 

So basically, I have 2 extra partitions if I'm reading the information in step 1 correctly.

So it appears that there are 3 options.
1) Delete extra partitions
2) Resize the partitions
3) Redo the work

 

I'm using a Western Digital 6tB WD60EFRX.

I was able to successfully issue the "mfstool copy -aiM 4000 /dev/sdb /dev/sda". The Tivo thinks its a 4tB drive.

I get the "too many partitions error" when I issued the command "mfsadd -xM 4000 /dev/sda".

In note 7, I posted the full output of the "msfinfo -d" command.

Gary
