Title: DNS 345 and HOTSWAP (hot plugging??)
Post by: v3rcingetorige on November 03, 2013, 11:39:16 PM

My old DNS 343 don't have HOTSWAP funcion.
I want change it with a new DNS 345.
Can i change one HDD on a raid5 array on a 345 without loose data? (on 343 isn't possible..)

Thanx

RAID arrays created on legacy ShareCenters (DNS-321/323/345) are not transferable to the newer ShareCenter series due to changes in the filesystem used to format the HDDs. It's possible (but not guaranteed), that HDDs with Standard Configurations on legacy ShareCenters may possibly work with newer ShareCenters.

Ok a must backup all data from DNS343 to a "high capacity HDD", transfer HDD from 343 to 345, rebuild RAID and upload all data from "high capacity HDD" to the new 345...

But if one hdd on DNS 345 fails, can i raplace it with new one without lose data? (on OLD 343 is not possible replace an HDD with a New one.. The DNS 343 "Want" to rebuild raid5 and i loose all data!!!)

Thanx

I had a typo in my last reply, which should have read "RAID arrays created on legacy ShareCenters (DNS-321/323/343) are not transferable to the newer...

Addressing your question, If a HDD fails in a RAID-5 array, both the DNS-343 and DNS-345 should successfully rebuild without issue. The DNS-345 has matured quite a bit since the legacy DNS-343. You can always perform some simulated failures with the DNS-345 to see how the unit behaves:

• Create a RAID-5 array in the DNS-345 and copy some data over
• Power down the DNS-345
• Remove one of the HDDs and reformat in a Windows PC
• Re-seat the HDD and power-up the DNS-345
• The DNS-345 should repair the array

and/or

• Create a RAID-5 array in the DNS-345 and copy some data over
• Power down the DNS-345
• Remove one of the HDDs
• power-up the DNS-345
• The DNS-345 should prompt for a new HDD and rebuild the array

I wonder if anyone already tried this first hand? I am keen on getting DNS-345 and setup as raid 5. However if 345 behave the same as its older brother 343. it's no use.


Thank you.
