Hope is not a plan... #19636384 [CLOSED]
Hello,
I will try my best to remove all emotion from this post/question/plea for help :D Purchased a new ReadyNas NV+ mid-2007 and until mid-2012 it ran without an issue (save replacing one drive). Had a wicked thunderstorm while I was away in July. Nas had shut down (assuming because of the storm - perhaps a surge). I went through various attempts to boot the system up. Finally got it online and could see it through Frontview. July - Two bad discs, replaced them, then September - two more bad disks, replaced them too (not the previous replacements). Updated the firmware and had never been happy with the way I'd tagged my music files to begin with, so decided to start from scratch. Factory reset. The new setup was taking shape beautifully. I had ripped cd's A-M and was slowly transferring the files to the Nas, was able to stream the music. Everything was ticking along until yesterday around noon.... Was transferring music folders/files just ripped through Max to the Nas and lost connection, system hung up. On one reboot received a 'Kernel Panic' error. Performed a hard boot and ran two mem tests - both 'mem ok'. Disc two is now flashing, meaning bad disk. Will be off to pick up a new disc today.
Here's where I get emotional, I'm wasting an enormous amount of time on what was a fantastic system at one point. I'm in an endless cycle of reboot, resync, volume check, file scan, mem check, this is bizarre and quite frankly confounding me. SmartChecks on the individual discs (including disc two that the Nas' LED's suggest is bad) suggest everything is okay. Sometimes I can connect via Raidar and Frontview, sometimes I can't. There's no rhyme or reason to it. I've pulled disc two out and am running another mem test as I compile this post.
Has anyone had a similar experience? I'm almost at the 'throw it out the window' part of the cycle. I know I haven't lost the data I've written, because every so often I can get into the system via Frontview, but this endless cycle is bringing a true music lover down... I'm losing hope and patience.
For the record, I run a complete MAC environment:
Hardware: MacBook Pro 8,2
OS X 10.6.8
Timecapsule (although not using it for backup or for streaming iTunes (just as a router))
Cat5 hardwired from my Nas to my Sonos system (but running through Timecapsule to support multiple Sonos bridges/connects)
RAIDAr 4.3.4
ReadyNas Firmware 4.1.10
4 - 1TB Discs Western Digital Caviar Green

My new question is this - There is no data on the NAS with the exception of the OS. I have 4 1TB disks installed. Each disk has 927 GB allocated. The display on the front of the NAS unit shows 2.6/2.6 TB available. Should it not read 3.7/3.7 TB available?
Your NAS is using X-RAID (essentially an expandable RAID 5 volume).
In X-RAID (or RAID 5), the NAS reserves 1 disk for redundancy and uses the remaining disks for data storage. Of course, drive manufacturers use "marketing terms" for capacity (where 1 k = 1,000 bytes, rather than 1,024 bytes) to give the drive the appearance of more space. A 1 TB drive really only has 927 GB of capacity (using 1024 KB blocks). Multiply by 3 to get overall capacity (remember, the 4th drive is for parity/redundancy) and you end up with about 2.8 TB. Subtract OS, overhead and snapshot space and you get pretty much what Frontview is reporting:

This is about right. My Seagate 528 1TB drives show 931GB each and 2.7TB total available.- You may also wish to look at the X-RAID Volume Size Calculator (see link in my sig).
- @dbott67, maxblack and mdgm - thank you for the explanations regarding the X-RAID Volume Size for my NV+ - it makes sense now.
My case is almost ready to be wrapped up. I have a few questions left for my Level 3 Tech, Aaron Tak, who has given me phenomenal service. We're still trying to figure out why this all started and why I was getting the USB Mount Failed alerts during the resync process.
But, my NAS is once again fully redundant, my music is streaming again and, Aaron showed me how to quickly back up my NAS to my Time Capsule so I didn't have any data loss during the procedure to restore the NAS.
As a side note, when I pulled up the SMART info for all four disks, it is quite obvious that Western Digital WD 1TB Green Disks should not be on the approved list for the NV+. I currently have three Greens and one Red in the unit. On the Red disk that was installed on Friday, (power on hours 17), there are zero, NO, none, nada LCC's registered, but on the one green disk that was also installed on Friday, (power on hours also 17), there are 411 LCC's (this was accurate as of Saturday morning). I will be changing out all three Green disks for Red - ASAP.
Thank you to everyone who chimed in to help.
