RN316 does no finish booting and OS install gives error "could not extracting files) last FW

hi all,

StephenB Hope you feeling better!

I am feeling so grateful!!! Even if I might not get all the data back, I think I am getting most of it. Got 5 putty consoles up and copying data right now.

Copying most of the data to the USB 7 TB disk, from there to the new Asustore AS6510T.

This one got 2 NVM .2 disks as cache and 24 GB ram, 29 Tb , atom 4core proc.; 2 x10 Gbs and 2x 2.5 GB NICs and its Linux OS is way ahead.

Once done, I am planning to install a new fan in the RN316. I saw on the web that Netgear has inverted and remixed the standard fan connectors so that it is needed to re-order the cable pins in the fan so not to short-circuit it and burn the fan.
It might be the same for the power supply, which I am also thinking might be a good idea to replace it.

Anyone confirms this and know how to do it?

All comments welcome, thanks a lot everyone. cheers,

Great!  Good luck with the new NAS.

I'm definitely doing better, but it will take some weeks to fully heal.

Hi all,

StephenB I am glad you are getting better, collarbone takes long to heal, be patient.

 there was a pb with the copy, it only copied 95 Gb out of terabytes. I was looking to the 7 Tb disc to be full. I am not sure what happened.

I will try again, this time I will only start one job at time. I guess what I need is to move the data to the disk this way the next job can move the data left over.

Could you help with the syntax for the move job, please? Thanks.

BR

Looking back at the command I posted before, I see I made a mistake: the -r should have been a -R.  So you can just use

cp -Rpuv /data /mnt

Note the -u option.  That means "copy only when the source file is newer than the destination file or when the destination file is missing".  So it won't recopy the 95 GB that's already been transfered.

Rather than moving files, I suggest using these commands to double-check that everything is copied:

find /data | wc -l
find /mnt | wc -l

The first command gives you the number of files on the data volume, the second gives the number of files on the USB drive. These can take a little while, as they are scanning the entire file system. 

You can also check total storage using

du -sh /data
du -sh /mnt

These also can take a while.  They might not match exactly, since you have two different file systems (NTFS and BTRFS). 

The -h says to give the results in "human readable" units (M for MiB, G for GiB, T for TiB)

StephenB Brilliant, thanks for sharing it. nice to be able to verify and copy only the newer data.

The pb is the data will not fit in the disk, unless I move it out to the PC to make room for the next batch, each time it is moved to the disk. The data is not being updated on the PC or the SAN.

The idea is that I move part of the near 13 Tb data to the 7 TB disk, move what's in the disk to the PC, to make room for the rest of the data left in the SAN, as the 13 Tb data won't fit in the 7 TB disk. does it make sense?

Thanks and BR,

Ok.  But I still am hesitant to move data, because it deletes it from the source.  If something goes wrong, you end up with needless data loss.

Can you post the output of 

du -h -d 1 /data/

 If the largest share will fit on the USB, then we could copy one share at a time.

As long as no single share or directory has more than the 7TB so you can copy a sub-section of files each time, that "bucket brigade" method should work well.  If you have one that exceeds that, then copying alphabetically might help select a small enough group.  Just remember that in Linux, upper/lower case matters.

Back in ancient times, we called it "sneakernet":  carrying disks (at that time, floppy ones) between computers to move files (wearing your sneakers). 

StephenB , this is great, I wonder what is causing the copy of Documents stop in the middle when it encounter an old folder containing a copy of a USB drive..

How to copy things alfphabetically?

I am currently using folder names for copying, eg., 

# cp -rpv /data/Software .

root@3C62350D01347:/# du -h -d 1 /data/
0 /data/home
18G /data/.apps
0 /data/.vault
1.9M /data/._share
6.2G /data/Pictures
71G /data/Videos
270G /data/Music
531G /data/Documents
0 /data/.timemachine
482G /data/Freaks
20G /data/Documentation
1.9G /data/Podcasts
254M /data/eBooks
36M /data/Transfer
488G /data/Audio
16G /data/HdAProdz
1.4T /data/Software
130G /data/OneDrive
8.4T /data/BackUp
0 /data/AmazonCloudDrive
8.0K /data/DropBox
16M /data/GDrive
0 /data/.purge
1.4G /data/uFreak
407M /data/ODB
14G /data/DZI
453G /data/VSTIData
0 /data/Video
13T /data/

Thanks,

Ok.  So everything except BackUp will fit on the 7 TB drive - which is probably 8 TB (~7 TiB).

Unfortunately, there is no simple way to exclude a folder with the cp command - but we can easily switch to rsync.

rsync -avzh --exclude '/data/BackUp' /data/ /mnt/

Note you can enter this after your current copying is done.  Rsync is incremental, it will skip the folders you've already done.

I don't know, but it is worth looking again after using the rsync command - that might manage to get past this problem.

StephenB Brilliant, I hope it does sync the missing data.

I have been comparing the sizes of the folders we saw with the ones already copied to PC and is missing most of  the data. I wonder why.

The copy job for documents only copied 136 Gb when it should had been 531 Gbs.

This happened to all copies, they are all missing Gbs. If we didn't retrieve their sizes i would not even know for sure.

Best,

To copy alphabetically, you would use something similar to # cp -rpv /data/Software[abcde]* ., which will copy everything starting with a, b, c, d, or e.

Are you also checking the file counts?

StephenB how is going?

Is it possilbe? 

I am not sure how to count files in the RN316 to compare with the disk.

I posted the commands earlier:

find /data | wc -l
find /mnt | wc -l

 You can of course run this on a folder, and not on the entire volume by adding the foldername to the path (i.e., find /data/foldername | wc -l )

StephenB  Hope you better!

I have tried to copy and to sync dozens of times, it always stops short from copying all files. 2/3 of the data is not being recovered.

any ideas? would you be willing to try a remote session? I would much appreciate it.

Thanks a lot,

Unfortunately I'm not in a position to do that.  Among other reasons, there wouldn't be any contractual protections for either of us.

Are you seeing any errors on the screen?

Can you identify a specific file that isn't there?  We can then try a cp command that is just for that file, and see if we get an error when we copy it.

StephenB Hope you feeling better !

no errors on the screen, just the file copy always stops at this point:

'/data/Documents/R-TT/R-Undelete' -> './Documents/R-TT/R-Undelete'
'/data/Documents/R-TT/R-Undelete/Lexar SFF-SSD 0.rdr' -> './Documents/R-TT/R-Undelete/Lexar SFF-SSD 0.rdr'

How can I sync , what syntax to use, only one folder? 

BTW, this comments still syncs the Backup folder: 

# rsync -avzh --exclude '/data/BackUp' /data/ /mnt/

Thank you,

cp -Rpuv /data/Documents/R-TT/R-Undelete /mnt/Documents/R-TT

should copy R-Undelete and any of its subfolders.

Yes, I see that.  Not sure what I have wrong there, I'll need to get back to you on that.

Though you could try

rsync -avzh /data/Documents/ /mnt/Documents/

and see if that copies the R-TT folder.
