  Stuck on self testing 7700 v1
Posted by: fiasco - 07-18-2018, 09:20 AM - Forum: N7700/N8800 - Replies (3)

My n7700 turned itself off and is now stuck on self testing.   There is a quick faint chirp when it starts up.   The red trouble led remains illuminated and it stays in self testing.

What are my options with regard to purchasing another thecus NAS and moving the drives to it to recover the data?   Can I purchase a n8880u and install move my drives to it to recover the data?    If so, how difficult is the process?

  How to get iTunes library working on N7710-G?
Posted by: mikea - 07-14-2018, 07:11 AM - Forum: NAS from 2 to 5 bays - SMB - No Replies

I had this working at one time, but can't figure out how to do it again.
I have copied my iTunes library to my N7710-G.  My goal is to have the library available to
multiple devices over my network.  I am now trying to get my Sonos to view the library for
playback.  So, in my Sonos app, I go to preferences, then Music Library Settings.  I type in
the path to my music, \\N7710-G\iTunes_music\Music, and it then asks me for a user
name and password.  The admin name/password I use to view status of the NAS from a browser doesn't
work.  I have also set up a local user name/password but that doesn't work and my Itunes
login doesn't work either.  
What user name/password am I supposed to use to login with?
Thanks
Mike

  N7700Pro Stuck in Self Test - change drives to new chassis?
Posted by: yosini - 07-03-2018, 01:13 AM - Forum: N7700PRO/N8800PRO - Replies (1)

Hi,

We had one of our older Thecus servers start dropping off line, did a firmware update (with hindsight that was silly), anyway now we're stuck in the dreaded self testing mode. My question is - we have an identical spare server machine which is still working fine (although on the original firmware) - can we just swap all 7 drives from the 'self testing' server to the other spare server?

Is all the RAID information/firmware kept on the drives themselves? ie will it matter if the 'self testing' machine drives are RAID 6 and the spare machine is currently configured as RAID 5? Will the different firmwares make a problem?

Will doing this either screw up the 7 drives from the 'self testing' machine (drives are definitely fine, it's not a problem with them), or screw up the 7 drives from the spare machine when we put them back in?

Essentially I don't mind losing the data from the spare server, but I do need to recover the data from the 'self testing' server, so if it is as easy as putting the drives in a different chassis then happy days - unless it is likely to screw the important drives up and make then un-recoverable by another process (such as UFS explorer)

Thanks in advance

Cheers

Joe

  Recovering Data from N2310 HDD
Posted by: gratsoy - 06-30-2018, 08:40 AM - Forum: N2310 - Replies (1)

I've successfully recovered data from my single HDD that was inside a failed N2310. The N2310 died after a power outtage and I was unable to restore it.

Two options are available here: 1) Recover on Windows with a PAID program 2) Recover for free with Linux

1)
I used Disk Drill and recovered the entire contents with ease - HOWEVER, I lost all metadata. So I had ~1000 files that would need to be manually renamed and sorted. If you do some research, I believe there are paid programs that can detect the filesystem correctly and keep the metadata YMMV

2)
Using a linux PC, I recovered everything and maintained metadata and folder structures. You can likely do this using a Ubuntu Live CD/USB, but I have a purpose built Linux machine that I used.

From what I've read the N2310 is a powerPC based unit so it's filesystems are kind of goofy and not easily registered by Linux. In Ubuntu I was absolutely not able to mount the drive no matter what I did, but that doesn't prevent you from recovering the data. Instructions are as follows:

Install the drive, and make sure you have a destination with enough room for the files to be recovered to (I used an external hard drive USB 3.0)
I then opened up the terminal and changed my permissions to root (if you're unfamiliar with linux, be careful cause you can cause some damage while in root)

Quote:sudo -i

Next I installed mdadm and lvm2

Quote:apt-get install mdadm
apt-get install lvm2

Use mdadm to reassemble your raid (if you had a two HDD raid this should also work if both drives are installed), recursive is optional.
Quote:mdadm --assemble --scan --recursive

If you open up the disks appication you should see a few RAID array's. My HDD was 3 TB and I had an array "3.0 TB Raid Array" the device was called /dev/md0. Yours may be called something else but it will be along the lines of /dev/mdX
This is where all the files are. The other arrays are used by the N2310 for operational purposes and won't contain any data you would need to recover.

Next we need to check the block size, it's easiest to try to mount first then check.

Quote:mount /dev/md0 /mountlocation
mount: /mountlocatin: wrong fs type, bad option, bad superblock on /dev/md0, missing code page or helper program, or other error.
dmesg | tail
With mountlocation being a location I created to mount my drive, the message in red is the error you get. After doing the dmesg you'll get a response with a few lines. At the end you will see something along the lines of:
Quote:[449.322010] EXT4-fs (md0)" bad block size 65536
The numers in brackets likely wont be the same, but what we see here is that the block size for this file system is 65536 - again, I think this relates to the powerPC architecture. 65536 will be the same for all N2310s and likely most Linux Thecus rigs.

Next we debug the filesystem to recover our data
Quote:debugfs
open -b 65536 /dev/md0
ls

You'll now be in a window where it will list the folders in this root of md0, I had to hunt and guess here but there was a folder called "data" so I decided to look in there. Hit q to exit the ls

Quote:cd "data"
ls

At this point I could see all the folders I had placed in my NAS - and thus am ready to recover. Hit q to exit the ls

Quote:rdump "folder you want to recover" /location of dump

In my case it looked like this:

Quote:rdump "Movies" /media/username/TOURO

Since I had my external HDD mounted I dumped there, if you do the same you will need to use the similar format, /media/username/name of external HDD.

At this point debugfs will do it's thing and you wont be able to type anything in terminal. The cursor will return when it's done.

If your folders have spaces in their name, I believe you'll need to use a backslash like this:

Quote:rdump "folder\with\spaces /media/username/Touro

I spent way too long trying to figure this out - so I wanted to post a thread to give future users some guidance.

This same method should work for other NAS machines as well - most of these instructions I pulled from a guide on recovering from an LG branded NAS

  High memory usage?
Posted by: ngupta - 05-31-2018, 11:24 PM - Forum: N4100PRO - Replies (1)

I don't know when it started, but the memory usage of my N4100PRO is through the roof (85+% all the time).  I've disabled all network services other than AFP, and all application servers other than SSH, and it doesn't seem to solve the problem.

When I SSH in, I see that there are 6 httpd processes that are using almost 100k of RAM, even though I am not doing anything with the webserver.

I am on what I believe is the latest firmware, 5.03.02.


Any help you can provide is appreciated!

Question IMAP Port 993
Posted by: greatpotoo - 05-29-2018, 10:15 PM - Forum: N4200PRO/N4200Eco - Replies (3)

Dear Thecus community,

I have a THECUS N4200 PRO with firmware V5.03.02.8 on which I run PHPXMail

I am able to access ports 25, 143, 465 but for some reason I can't access port 993 for a secure IMAP connection - I tried a number of things but somehow I cannot figure out what is wrong - any help would be appreciated

The router/modem redirects port 993 to the NAS

the NAS however has port 993 listed as closed

Thank you Confused
