I have an LS-QVL/R5, firmware version 1.62, with 4 x 2TB WD drives in a Raid-0 config.

A couple of days ago I got a red light and a warning that one of the HDDs had failed. It still seemed to be working, as I was getting no data errors, but I shut it down anyway. I restarted and it came up cleanly, so I decided to kick off a disk check. Two days later, and it's still running! The web page simply says "Details Progress: Progress" and there's a helpful little spinning ball to tell me it's doing something!

I can't Telnet/SSH in as I get connection refused - I probably needed to enable it somewhere but clearly haven't done.

I have no idea how long to give it and no idea what damage I might cause if I just kill it? Anybody have any ideas, please?

Thanks

Phil

After another day I decided to kill it. Needless to say I stuffed the entire 8TB RAID partition!

So what have I learned? Never ever give your money to a bunch of amateurs like these. Who creates a process that runs for days without offering any indication of progress?

Don't take a risk with your data, even if it is fully backed up. It took me over a day to restore 7TB!

Stick with using a standard X86 box and Linux or Windows, even if it doesn't look as neat and draws more power. At least you have some meaningful diagnostics if things go wrong. And it is much faster to access than this piece of junk was.

Over and out!

Or get informed BEFORE buying stuff.
Unfortunately Buffalo is known for problems like this (bad
user experiences for serious problems; especially a GUI not
sufficient to recover anything serious).
To run a Buffalo NAS without UPS is unreasonably hazardous.
Running a RAID 0 on a Buffalo box is even worse.
There are other vendors for small NAS systems, not having
this kind of problems.
So it is not a matter of the CPU but the manufacturer.

Sorry to kick a man already lying on the ground. :-(

Btw. and not related to your problem, RAID 0 is always a bad
idea, nowadays. If you need speed, take SSDs.

No harm meant.

Thanks for the feedback. It's increasingly difficult to get fully informed about the nuances of tech problems with such kit. People with an axe to grind will spray their negative comments far and wide, people who have no issues tend not to bother posting, so how do you really get a balanced view?

As for your comments on Raid-0, you may have missed the bit where I said it's 8TB? Not quite within the budget to do 8TB SSD! I use Raid-0 to get large contiguous space, speed is less of an issue - I only mentioned speed as these things are incredibly slow!

Good point. Accepted.

You belong to a minority of RAID-0 users, which are aware that a NAS
is not a "backup" by itself. 99 percent of people seeking help here, do
not have a backup of their NAS data. So you should be pride to be part
of the 1 percent. :up:
