Looks like that filesystem is toast.

Hi Thisisnotmyname,
Ok, I will wait for confirmation after my post above of the results so I don't mess anything up further!
Many thanks, cheers!

Ouch!
Is that a common thing to happen?
A file system to just 'disappear' when the QNAP was running merrily along with no warning signs? Just a 'BEEP" and all is lost?
-- or did my commands/arguments from my ill-advised 'fixes' toast the file system?
Re: the filesystem? All of my devices were setup the same... would looking at my other 809Pro give us a hint as to the file system on the bad one?
Re: starting from backups... I'm only about halfway through a move (just moved back here at the beginning of December) so the backups are in a different country... on a different continent! We weren't scheduled to return and pick up the rest of our stuff that we don't sell until the end of March. (I couldn't bring everything back in one trip without risking damage to some of the components.)
I really would like to get access now, if at all possible... so I'm up for trying anything and everything!
Many thanks!

We'll probably never know what did it specifically but my bet would be on running disk utilities against it semi-randomly; I'm sure I don't have to tell you now that wasn't a good ideaCaptainCanuck wrote: ↑Sat Jan 12, 2019 4:03 am Hi Thisisnotmyname,

Trying to fix things from this stage will get pretty ugly and complex. Iterating through it via a forum may take until March
I guess lets start by getting more details about the (presumably) extX filesystem on that thing. Try this...
mke2fs -n /dev/md0
then post the results here.

Yes, I was taking Hydromorphone for a back injury and that stuff messes you up! At the time, I thought I was diligently following directions to solve my problem.... Once I was on reduced meds, my.... 'decisions'... looked quite different!
When I run:
mke2fs -n /dev/md0
My results were:
mke2fs 1.41.4 (27-Jan-2009)
mke2fs: Device size reported to be zero. Invalid partition specified, or
partition table wasn't reread after running fdisk, due to
a modified partition being busy and in use. You may need to reboot
to re-read your partition table.
Thanks, Cheers!

EDIT: (just noticed I lost this part in the post above after a bad copy/paste)
After a reboot, when I ran:
mke2fs -n /dev/md0
I received this result:
mke2fs 1.41.4 (27-Jan-2009)
mke2fs: Size of device /dev/md0 too big to be expressed in 32 bits
using a blocksize of 4096.
Thanks, cheers!

huh. Well if we can't even get superblock locations I don't know how we could go any further. I'm out of ideas.
I'm making a lot of assumptions though too and as was pointed out this system is pretty old so maybe it was initially set up different from what I'm expecting. Unless someone else has an idea I think you may be stuck waiting for March.

Did you see my 'Edit" to that info you quoted? It was lost in my first post due to a bad copy/paste.
After a reboot, when I ran:
mke2fs -n /dev/md0
I received this result:
mke2fs 1.41.4 (27-Jan-2009)

Is this what you needed?

Ok, thanks very much!
Hopefully someobody else will be able to chime in with something!
--or maybe someone can direct me to someone or someplace that could sort it out for me ? March is too far away for me to be able to rebuild from the back-up... (I guess because it's out of warranty QNAP won't be able to help?)
Many thanks, cheers!!

Qnap offer free technical support also on older systems. Your TS-809 Pro should be supported at least until 2020-12 according to the Qnap product support status page.CaptainCanuck wrote: ↑Sun Jan 13, 2019 9:10 am --or maybe someone can direct me to someone or someplace that could sort it out for me ?

If it's possible to recover your system, Qnap support should be able to help you.
RAID have never ever been a replacement for backups. Without backups on a different system (preferably placed at another site), you will eventually lose data!
A non-RAID configuration (including RAID 0, which isn't really RAID) with a backup on a separate media protects your data far better than any RAID-volume without backup.
All data storage consists of both the primary storage and the backups. It's your money and your data, spend the storage budget wisely or pay with your data!

Sorry for the late reply, that's excellent news! Thank you!
I'll contact them and hopefully I can find a resolution!
Many thanks everyone for your help, cheers!
