Error during drive upgrade - RN104 with Seagate NAS HDD ST4000VN000
Dear support, I just got a brandnew Seagate NAS HDD ST4000VN000 4TB NAS Drive. When I was doing upgrade, I am getting this issue. It remained there and the drive status is showing offline. I tho...
Fresh update:
After several attempts removing and once again building/syncing, it is producing the error: ERR: Used disks. Check RAIDar.
14th Apr, I purchased a new 3TB WD Blue drive (WDC WD30EZRZ desktop drive). I need this new HDD as a multipurpose buffer/spare/archieve/snapshot especially situations like these. After several reliability tests. Took the entire backup of my NAS data in the same. This took several hours due to 15MBps read/download speed. Anyway glad that I can able to read/retrieve everything. The WD Blue drive also worked very reliably so far. And noticed its temperature profile which is much better than Seagate.
Yesterday: 15th Apr, once the backup is 100% complete from NAS to WD Blue 3TB drive. Data is intact. Then I did a fresh NAS build. I built this time initially with 1TB Laptop HDD, 128GB SSD, 2TB Desktop HDD, (and removed the 4TB Seagate NAS HDD for a moment), this has reduced the fresh volume build/sync to just 12-14 hours.
The new build is successful. I documented the whole process in my Youtube VLOG (screen-capture):
https://www.youtube.com/watch?v=hQ0scDC239s
Once done everything, this time I set Network port mode initially: Active Backup
Benchmarked (1TB HDD, 128GB SSD, 2TB HDD): 23.5MB/s write, 26MB/s read
morning 16th Apr,
I changed initially to mode: Transmit Load balance: 30.2MB/s read, 26.4MB/s write
later I parmanently changed to mode: Adaptive Load balance: 31.6MB/s read, 27.5MB/s write
I managed dumping back some of the data from 3TB WD Blue drive to NAS since last night.
------------------
Since now that NAS done 100% sync/rebuild, I now added back the 4TB Seagate NAS HDD in slot-4.
It started resync. May be once it is fully done, I may do once again a fresh benchmark of read/write.
It is a great learning curve. I think in future I may shift 100% to SSD Drives.
I see a great temperature difference between HDD vs SSD even in intense load.
I hope once it is all set, I never want to disturb again.
But its a great experience. I can see the future HDDs will become obsolete very soon by 2018-2019. SSDs are going to dominate and eventually replace HDDs.
Right now HDD manufacturers are able to make huge capacity drives, but they are also lacking in reliability. We can compare this aspect with older drives (2000, 2005, 2009 manufactured), vs the HDDs manufactured these days. So I may never buy again a mechanical HDD :)
Hello kiran_kankipati,
I do hope you have backup of the data.
Regards,

It's not going to be tomorrow that SSDs price per TB will be at the level of HDDs.
Less than $400 for a 10TB HDD: https://www.amazon.com/Seagate-IronWolf-3-5-Inch-Internal-ST10000VN0004/dp/B01IA9GU0Q
$1400 for a 4TB SSD: https://www.amazon.com/Samsung-2-5-Inch-Internal-MZ-75E4T0B-AM/dp/B01G844OOO/
Or more than $5000 for >10TB SSDs.
Well the thing is how much one need for critical storage vs. bulk storage.
HDDs will be fine for sometime as bulk storage. But for critical NAS like storage (a home/SOHO user) SSDs will replace soon.
I agree that SSDs are 10-15 times in more expensive.
But there will be a sudden shift. It will come very soon.
I can see the pattern when CRTs are completely replaced with flat screen monitors/TVs LCD/LED whatever.
We can see now renewable energy sources getting cheaper than Coal/Gas.
Same with Film camera (movies) vs direct digital recording. Film is obsolete.
Dumb phones with Smartphones. Explosion of Android phone market.
SSDs will dominate by end of 2017. More new companies will emerge and replace HDD technology.
HDD tech will face serious competition by 1st quarter of 2018, by end of 2018 HDD will be gone 80% !
AMD Ryzen gives opportunity to everyone to own a high-performance computer at an affordable price.
For that we need high-performance DDR4 RAM, if so then equally high-performance storage like SSD.
At the moment SSD got expensive due to supply-demand situation. This will change, the bubble will burst !
cheers, Kiran

At the moment SSD pricing is moving in the wrong direction (higher), due to a shortage of NAND chips.
As far as long term trends, I think you need to add cloud storage into the mix as well. Fast internet + cheap cloud storage is an alternative to local storage.
