Storage / Re: Creating RAID5 on LS-QVLB10 fails

« Last post by 1000001101000 on December 31, 2020, 10:43:41 am »

If "-o" doesn't give you a working telnet (it does for most but not all model/firmware combos), you have some options:

For most tasks the "-s" option provides a good enough shell to do what you need, that will work for any configuration you can get ACP Commander to connect to.

You can transfer a telnet binary over using "-xfer" and then run it. I have that process documented here for a different model:
https://buffalonas.miraheze.org/wiki/Linkstation_LS520D#Telnet
**You would need to get the armel version of busybox for the LS-QVL

I believe this script works to enable SSH on the LS-QVL (using acp_commander):
https://github.com/rogers0/OpenLinkstation/blob/master/0_get-ssh/get-ssh.sh
**I haven't used it in years and don't really recommend messing with the built-in ssh like this but I added it for completeness

***Note that all of this assumes you use the newest version of ACP Commander from the github link I posted earlier rather than any of the older versions available elsewhere.

If you've reached the point that you find yourself wanting to modify the firmware form the command line you also have the option to replace the firmware with a Debian Linux installation. Details and installer files can be found here:

"Fake shell" with ACP Commander worked:

Code: [Select]

unused devices: <none>

Could not get the -xfer (-xferto) to ask for any file to send (included telnet in GIT repo). Is there any way to make telnetd (or even ssh as on LS220) permanent on this device ?

Looks like my option here is just to lean back and wait for a week..

I know about ACP Commander, but as the addons (for this model, I have archived the needed files for LS220) are no longer available, it won't work ..

You can get telnet access with ACP_Commander:

It might be failing that step because one of the drives is having trouble (bad sectors etc). I'd connect them to a PC and check them out before continuing if you haven't already.

Storage / Creating RAID5 on LS-QVLB10 fails

« Last post by peo on December 31, 2020, 09:08:36 am »

Because of previous failed attempts to create a RAID5 on my LS-QVLB10, I decided to go for a full erase (somewhere from the UI). It took something about three weeks of 100% activity on the disks, but now I at least know these disks should be reliable for continued use (or had their lives shortened by the 4x "write 0", "write 1", "write 0", "write 1" cycle).

I get the exact same problem when trying to create the array now as before erasing (and I even updated to the recently released new firmware version before trying to create the array):

Step 0: Select raid type and disks to include, confirm creation (ok + code)
http://tech.webit.nu/wp-content/uploads/2020/12/qvl-00-create-raid.png

Step 1: Progress 50%, "Failed to operate RAID array. Please resubmit after restart.
http://tech.webit.nu/wp-content/uploads/2020/12/qvl-01-failed-to-operate-raid.png

Step 2: Logged in again, "Array 1" is listed in the "Disks" section, but also listed under "RAID Array" as "Not configured".
I can (and also did once) reconfigure the RAID5 on the same devices as before.
http://tech.webit.nu/wp-content/uploads/2020/12/qvl-02-disk-raid-status-after.png

Step 3: NAS-Navigator shows both "unformatted" and "resyncing" (without indication of progress)
http://tech.webit.nu/wp-content/uploads/2020/12/qvl-04-nas-navigator.png

LED status: RED long short short short short
according to http://en.faq.buffalo-global.com/app/answers/detail/a_id/12769
"I14 The RAID array is being checked."

Cannot get into the NAS by Telnet or SSH (since this is "unsupported" but was possible to patch before the death of buffalo.nas-central.org) to see what's going on.

Should I just lean back and wait a week or two until the RAID checkins is done (which should be instant because of four empty drives besides the NAS OS partitions) ?

Hi,

Apologies for the late reply.

I think you maybe right. I'll get it into the pc when time allows and use the WD software to check it over. If that works I'll use WD to fully nuke the drive and start again.

Thanks for all your help!

You need the recovery image to reinstall the OS.

Thank you. How can I get the recovery image?

They provide a downloadable recovery image for this model:

Thanks
I've already tried the Buffalo recovery image.

Right on. Can you provide more detail about what happened when you tried?
