Expanding RAID volume on NAS326 is not working

Tukemoni · March 2020

Hi. Thanks for the advices. I manage to edit and save the file, but for some reason I'm not able to login over telnet after "power off" command. Any further help is highly welcome.

User mistake as usual. Managed to telnet and got the system to work with expansion. Thank you Mijzelf!

Got it working replacing my 2x4TB drives with two new 2x10TB drives.
Maybe some steps can be skipped, but for good measure I'm going to show everything I did.

Removed one of the HHD:s from the NAS and inserted a new HDD in it's place. In the admin-panel (//NAS326) I could see the progress. It took roughly 8 hours.
Repeated with second disk. Kept the old disks safe in case of failure.
Enabled SSH (and Telnet just in case) on the NAS using the admin-panel.
Installed Putty.
Inserted NAS IP (without any prefix), Port 22 and Connection type: SSH in Putty. IP can be found in admin-panel --> Control Panel.
Loged in with the admin account in the command window that poped up.
Typed "su" and had to provide admin password again.
Pasted and ran "vi /etc/init.d/rc.shutdown".
Pressed "i" on keyboard.
Looked for "#swapoff" and pasted theses lines after that line:
/sbin/telnetd
/bin/sh
Pressed ESC-key and then typed and ran ":wq".
Closed Putty.
Opened Putty once again, using the same IP and Port, but select "Telnet" instead of "SSH" as Connection type. A new command window opened and I had to login again. I propably ran step 7. again.
Pasted and ran "umount /i-data/sysvol"
Pasted and ran "e2fsck -f /dev/md2". Action took a few minutes.
Pasted and ran "resize2fs /dev/md2". This action took a while longer.
Pasted and ran "killall -9 /bin/sh".
Restarted NAS by pressing the physical power button.
Loged in to the admin panel and could confirm resize. Disabled "SSH" and "Telnet" again.
Made 10 cheers for Mijzelf and Gunslinger.

Hello Guys!
Unfortunately the steps written above are not working for my 326. I had 2 pcs 1TB discs (WD10EFRX) in Raid1 in my NAS, and want to change them to bigger ones, and have bought 2 pcs 6 TB (WD red WD60EFAX). The vi editing function can be done, but during telnet the umount is not allowed by system. Can this be because of the new firmware for example (I have the last existing installed approx 1 month ago)? Thanks for your kind help!

Mijzelf · June 2020

I cannot imagine the firmware changed at this point. You were able to find that '#swapoff'?

What processes are running at that moment? Run 'ps'.

Dear Mijzelf,

It was done as it was in the comment of Joonas, found swapoff also, entered the mentioned things.

ps was like this:

You have lots of daemons still running. Joonas list has one fatal flaw. After point 11 'enter :wq' you should run 'poweroff' to initiate the shutdown.

Attila76 · June 2020

Dear Mijzelf,

Thanks!

As I don't know too much about Linux, may I ask you, what do you mean "After point 11 'enter :wq' you should run 'poweroff' to initiate the shutdown." As I understand: after exiting the vi, should I run the "poweroff" function? Sorry to ask you stupid things.

Mijzelf · June 2020

The script /etc/init.d/rc.shutdown is used by the firmware to stop all processes and unmount the data partitions before powering off or restarting the box. What we do is putting some extra code in that script to get telnet access after the script has cleaned up the air. The ':wq' command exits vi, so that is the moment the script is prepared.

Now you have to shutdown the box to get the script running, which can be done by executing 'poweroff', or by the webinterface.

Attila76 · June 2020

Dear Mijzelf,

It was running, thanks!
