After reading another post about a hardware failure, I got to thinking about my old, dead MBWE blue rings. So the question is this: How was your failure experience? When you got a failed drive or a failed logic board what was you experience like for recovery?
I'll start out by sharing my story:
I personally ran mine off solar power, so direct, regulated 12 VDC and my motherboard died. I was so upset, but dug in for a recovery. When I reset the device, I noticed it was reading and writing a lot! I quickly SSH'ed into it to see it was formatting the DISKS! I ended up loosing my data because the motherboard came back on and it started REFORMATTING with RAID1 over my 2 good disks. I came back to find both my drives blank. Even data recovery was near impossible because Linux erases the partition table at the beginning and end of the partition at the same time!!!! I checked and both drives were mechanically OK and worked when mounted READONLY using FUSE and the EXT2, EXT3 plugin on my Mac. So what gives? READONLY, but showing 999GB of blank space. GREAT!
Here's a tip for anyone doing RAID - Linux is about THE WORST thing to use for RAID because the way the filesystem is written (as mentioned above). Windows, as bad as it is in MUCH better in regards to recovery because it doesn't touch the end MBR until everything has been completed. It's because of that I can easily say that Linux filesystems have a LONG way to go in order to be accepted in the enterprise world. If you're running this for your company, think twice. It's not a SAFE device. Even if the DATA is ok, what happens when the hardware fails? Can you easily, quickly, and cheaply replace it? I DOUBT it. THat means downtime. A better solution is needed and WD's support both HARDWARE and SOFTWARE is terrible. YES we can hack this thing, but should we HAVE to? Without the hacks this thing is a TURD at best. A REAL solution would be to do RAID5 or RAID6. That is the ONLY way I could recommend using a Linux filesystem for IMPORTANT data. Otherwise you're playing Russian Roulette with your data. I'm not exaggerating here.
Sorry to sound negative, but I'm being honest and realistic. I know the negative sides of this device well as I've experienced the worst, and could NEVER look someone else in the eye and recommend such a product. EVER. It's a fun toy at most. Nothing more. You've been warned. I hope this is helpful to someone like me that didn't realize the risks when I started using this device. After an EXPENSIVE data recovery I've learned my lesson about RAID1, Linux, and small hardware like this…… it's DANGEROUS at best.It would be *MUCH* easier to use a mini-itx solution on 12VDC and use a standard distro with RAID5. You'd at least have some support/recovery options if the hardware fails.
Now, Over to you and YOUR experiences with HARDWARE failure on the MBWE blue rings.
