There were only maybe two crashes where the UPS couldn’t sustain power long enough for me to shut down the system gracefully, yet I never had any issues up until now of powering it on and getting back to life. I kept the unit safe, cool, and free of dust during all those years, and always had it connected to a pure sine wave UPS system. I had treated and attended this NAS with the utmost care, purchased good, solid drives that were on the hardware compatibility list for this model, and run preventative health checks and maintenance like clockwork. I was dumbfounded, to say the least, and extremely agitated and upset to say the most. That was apparently enough, coupled with the exodus of disk two, to call this volume crashed. How is that even possible? I checked disk three and prior to it having only one bad sector (all other drives had zero), it now showed as having found two additional bad sectors. Um, what? Disk two, miraculously and mysteriously just gone from the group. In inspecting that disk, it showed as simply “not initialized”. With four drives in a Synology Hybrid RAID (SHR) configuration with a single drive of fault tolerance (basically, RAID-5), upon power up it was now telling me that disk three was “crashed” and disk two was mysteriously gone from the disk group. checks monthly, plus data scrubbing) suddenly and without warning went from perfectly functional on day 300, to, after having been powered off and in a box for seven days and powered on in my new house, deciding that the entire volume and backing disk group was crashed. This NAS, which had been in service for almost a year continuously and a picture of health (at least, as reported by Synology’s DSM software which performs basic and extended S.M.A.R.T. All of that seemed to come to a grinding halt about a week after I moved states. Outfitted with four 2 TB Western Digital Red drives (build for use in a NAS) that spin at a tepid 5,400 RPM, it isn’t a rocket ship, but coupled with PernixData in my Dell R610 servers, it was actually quite responsive and, at times, speedy. I expanded its use to include my music collection, movies from my home library, Veeam backups, and sundry other purposes. I have run between 10-60 VMs on this NAS and it has, despite not being the best performer, been very reliable and trustworthy. I have an extensive set of equipment at home that I use to test different products and model customer scenarios for my own education, enjoyment, and to examine problems facing customers in hopes of finding a solution once I put myself in their situation. I bought this NAS several years ago to serve as the cornerstone of my home VMware lab. What led up to this now unfortunate situation that is causing me to have heart palpitations? Read on… It’s definitely a moment of anxiety for me, because at this moment, I am having to rebuild and start anew with my 4-bay Synology DS412+, the NAS I’ve been using in my home lab for the past few years. I look to my left and patiently wait for a vertical row of four green, blinking lights to calm themselves. I’m inside, at my desk on a Sunday morning having just had some coffee and not in the best of spirits despite looking out the window at a beautifully sunny day on a well-coiffed lawn.
