Adding a 3rd disk: issues
Hi all,
here's my problem:
Pre Configuration:
Thecus N5200BR
Firmwre 2.00.01
2 Seagate 7200.10 500Gb configured as Raid1
Bought a Samsung 1 Tb disk which I wanted to add as a
single disk just to increase the available space that
was running out.
Drive has been recognized fine from the system, but I'm completely lost between raid expansion, migration, spare
disk etc...
I first did a Raid migration (selecting the 3 disks)
using one of the options the system gave to me: Raid1 to
Raid0. It took about 10 hrs but went fine.
Then I went for Raid expansion but it said no space
available to increase Raid.
Then I upgraded to firmware 2.00.04 and now I can enter
the option Raid expansion but it asks a couple of
questions about making data backup cause of power loss
issues during the process, write [Sì] (that is Yes in
italian) to confirm the operation, but then nothing
happens.
I have tried to write in the dialog box "Yes" (in
english, my language system is italian) and it seems to
start the expansion (a new screen appears) but it
doesn't do anything.
As said I'm lost, colud you help me?
Here's some info from my system. Feel free to ask for
more and I'll provide them.
Thanks guys

start the process but then nothing happens.

What's that "doesn't contain a valid partition table" output?
I'm currently running a filesystem check via N5200 WebUI.
Edit: run it and it didn't report any issue as far as I can understand the output:
Code:
[2008/1/19 9:22:53] /dev/vg0/syslv: 28/262144 files
(0.0% non-contiguous), 16449/262144 blocks
Risultati
RAID [ 3,4,5 ] Volume sistema : Codice di uscita = 0 ,
Nessun errore.
RAID [ 3,4,5 ] Volume dati : Codice di uscita = 0 ,
Nessun errore.
Sorry for this vey long post, hope someone can help me.
Thanks again.

Just adding some strange output from the logs.

As you can see it reports expansion fail in one section and RAID resize successfully in the other (information) one. Obviously the second statement is not true. The process (only by clicking [Yes] (see my previous post) last just 2-3 seconds and nothing happens.
I still have 1396 Gb of available space that seems I can't use...
What's wrong?
Thanks
Re: Adding a 3rd disk: issues
Dear Sir,
Please mail to support@thecus.com, and provide an IP address and port 21/22/80/443 with web pass for use to accesss and verify possible issue.
Yvon.
Re: Adding a 3rd disk: issues
Thanks Yvon for your reply.
I think what you suggest could be a little bit difficult to do cause my N5200 box is behind a Nat implemented by the ISP and that I can't manage at all.
I actually opened a ticket at the Support Center.
Just a question: can I expand a Raid0 with 3 disks that is actually using 25% of its data capacity?
Re: Adding a 3rd disk: issues
Dear Sir,
Seem your system with some abnormal parts, lead to system unable to expain the space, thus we need access to your N5200 for analysis possible reason.
Yvon.
Re: Adding a 3rd disk: issues
Just to take other people, who could be interested in this topic, informed, I got a reply from Thecus eSupport service after having opened a ticket and have provided some commands output, conf.bin, etc.
Anyway here it is:

At this point, it would be best to backup data and re-create RAID, it would be much "cleaner", and have less problem down the road.
Best Regards !
