ReadyNAS error: "mount_block_root+1f1"

ReadyNAS error: "mount_block_root+1f1"

After installing the 6.7.3 firmware (6.7.1 > 6.7.3 upgrade), I'm seeing the error message "mount_block_root+1f1" on the LCD. I was going to try the USB Recovery method, but I saw in this similar thread that it isn't working as a go-to solution. I see @mdgm-ntgr has been able to solve this error for @McRob1, so I'm hoping he can do the same here and spell out the steps involved.

Re: ReadyNAS error: "mount_block_root+1f1"

USB Recovery with a variety of thumb drives, syslinux.exe versions and 6.7.3/4 didn't work on the unit that was having trouble.

 

Netgear sent a replacement 314, and the USB Recovery process worked great (on the first try!) for updating the firmware.

 

So the problem was that 6.7.3 effectively bricked my unit.

Re: ReadyNAS error: "mount_block_root+1f1"

USB Boot Recovery is the solution. Be sure to right click on usbrecovery.exe and select Run as Administrator.

If USB Boot Recovery doesn't work for you you can try multiple USB keys. Some USB keys are incompatible.

 

Some users who've had trouble with creating a USB Boot Recovery key with usbrecovery.exe have had success with Rufus

 

With Rufus you'd select the MBR partition scheme for BIOS or UEFI and select FAT32 as the filesystem (default) and the default cluster size.

 

Once the mount_block_root error is dealt with if there are any remaining issues we can see whether we can look into those.

Re: ReadyNAS error: "mount_block_root+1f1"

It's not working. I tried using a 4GB SanDisk Cruzer, but the 314 kept booting as normal even though I was holding the Backup button. That resulted in the "mount_block_root+1f1" error.

 

Tried formatting the same USB drive using Rufus, but the instructions were unclear. Is "FreeDOS" the right choice? Do I run Rufus and then run usbrecovery.exe? Do I transfer the contents of a USB created with usbrecovery.exe to a Rufus-formatted USB?

 

Then I tried a Patriot 8GB USB drive. Now the 314 is in this weird state where it says "Netgear Storage / Welcome [ ]" and the power button is flashing. There doesn't appear to be any USB disk activity.

Re: ReadyNAS error: "mount_block_root+1f1"

The disk needs to be syslinux bootable.

 

The same contents of the x86 folder that usbrecovery.exe puts on the USB key need to be put on the USB key.

 

Rufus should put the syslinux boot loader on the USB key itself if you chose the correct option.

Re: ReadyNAS error: "mount_block_root+1f1"

If you have updated to 6.7.3 and ran into this issue please try USB Boot Recovery with ReadyNAS OS 6.7.4 which is now available!

 

If you have not yet upgraded please upgrade to 6.7.4 rather than 6.7.3. If your system has already been fixed I would still suggest updating to 6.7.4 the normal way using the web admin GUI.

 

If you can't do USB Boot Recovery despite trying multiple different USB keys and following the directions you'll need to contact support.

Re: ReadyNAS error: "mount_block_root+1f1"

OS 6.7.4 doesn't help really!

 

I've update the RN516 after the security Mail from Netgear from 6.7.1 and they work after the Restart.

And so I also update also the RN316 from 6.7.1 to 6.7.4.

 

Now after some Days are both RN bricked with "mount_block_root". 😞

 

"USB Boot Recovery" only ends with "boot from external USB" and flashing USB-LED.

I try different USB's and one of them is located next to the RN316, because they done Recovery some time before.

Re: ReadyNAS error: "mount_block_root+1f1"

You could try using Rufus to create the recovery key and/or perhaps try an experimental version of USB Boot Recovery with some improvements: https://www.readynas.com/contributed/mdgm/usbbootrecovery/usbrecovery.v2.0.R15-T3.zip

Re: ReadyNAS error: "mount_block_root+1f1"

Same thing happend to me on 516. Upgrade to 6.7.1 to 6.7.4 seemed OK.

After power cycle the next day, I'm now getting:

 

"mount_block_root+1f1"

If all else fails you could contact support.

If you are the original purchaser from an authorised reseller it would still be covered by the 5 year limited hardware warranty from the date of purchase.

Re: ReadyNAS error: "mount_block_root+1f1"

Thanks. Confirmed that using the experimental USB Boot Recovery (usbrecovery.v2.0.R15-T3.zip) worked.

This system now boots and files seemed to be intact.

The new USB Boot Recover does help to Start. The RN516 is Running again.

Next try at rn316 today.

I just upgraded to OS version 6.7.4 and it also practically bricked my unit. Now I'm getting this error at bootup. Although the first reboot after the upgrade went fine. I will try the USB recovery method.

 

What's the accepted method for the USB recovery? Do we need to downgrade to before 6.7.3?

In particular, do we install the latest 6.7.5 image? I have downloaded the experimental USB recovery tool and placed the 6.7.5 image under x86/, but my when I boot my RN314, it does not go further than saying "Boot from external USB".

Re: ReadyNAS error: "mount_block_root+1f1"

So is that the solution when it fails and you went through all the steps, booting to a valid, prepped, FAT32, 32gb thumb drive?  Get them to send a new unit? 

 

I ran through the posted solution (using fw 6.7.5), and it was booting to the USB drive, but never said anything about firmware.  Then got same error message (mount_block_root+1f1)

 

I'm going to play with mine some more-- maybe try to boot to an older firmware.  The original failure was after I told it to upgrade to 6.7.4...   

 

This unit is an RN716x with 6x6tb drives (=single 27tb volume), using firmware 6.7.1 (last time it worked).  Been in service for almost a year with no problems until now.

I have 3 others just like it that all went to 6.7.4 okay, plus some RR3312 (12x10tb=90tb volume) units that also upgraded to 6.7.4 just fine.

Yes, the new unit was the solution. And I think that's confirmed by the fact that the new unit carried out the USB Recovery process successfully using the same USB stick that didn't work on the old unit. Believe me, I tried every USB stick I could find and every variation of the USB Recovery software.

 

I have a legacy Ultra 4 that upgraded through all the 6.7.x firmware releases without incident. Still waiting to see how 6.7.5 works for others before upgrading, though — once bitten, twice shy.

Well, we just fixed ours by going through the process again with a smaller (16gb) thumb drive!   Now has 6.7.5 and seems to be working fine.

 

Thanks for the help!

I was able to rescue my unit using the USB recovery tool with a different USB stick, too. I think forgetting the "Run as administrator" was the problem the first time. Or it could be that the first stick I tried was unbootable for some reason (some are like that).
