TS-1685 on QTS 5.2.6.x DataVol1 (System) - Replacement Options

English Storage
1

Is it possible to replace DataVol1 (system) currently residing on a SATA-based SSD RAID 10 on my TS-1685 with a new DataVol1 on an internal RAID 1 PCIe-based NVME disk without “blowing up” the data disk DataVol2 currently up and running or will I have to reinitialize the entire NAS from the ground up to get a new DataVol1 up and running?

I was unable to determine if this is a possibility from wading through the documentation and thank you for your thoughts.

You can remove the current System Volume, add a new system volume and promote this to system (via shared folder management)

In that management you should be able to choose the volume to promote, if not, you can detach the DataVol2 (via GUI or physically via eject and reboot) and make the new SSD volume the only one present at the time

Thanks dolbyman!

I see the option to detach DataVol2 so here’s the plan:

  1. Detach DataVol2
  2. Install the new hardware for my desired new System volume or DataVol1 and configure it.
  3. Try and remove the current DataVol1, if allowed, or, if not, simply physically eject the disks and reboot to the new DataVol that will, hopefully, become the new system volume.
  4. Try and Recover the previously disconnected DataVol2.

A generic question about RAID synchronization: Why does it take so long especially considering the RAID is brand spanking “new” and there is no data on the RAID whatsoever. I mean, without any data in the volume, what is it tryaing to synchronize?

(Dolbyman, is “dolby” a reference to the old noise reduction system that we all used back in the analog tape-recording days? I remember that I had an outboard Dolby unit that could be used to remove noise from an underground FM radio station I used to listen to. Every Sunday evening, they’d transmit their reference level audio signal so that I could calibrate my Dolby decoder that I listened through. Boy, those were the days!)

That is always the case on mdraid (faster exceptions are RAID levels with bitmap enabled), but the RAID itself has no idea what the blockstorage above contains (empty or full of data) it needs to do a full sync based on pairty info.
ZFS does resilver only based on storage used (You need a QuTS NAS for that)

While it’s the same company, I based my nickname on my interest in multichannel audio formats, that started in the mid 1990s. Dolby is the most prominent of them all [)(].

If everything goes according to plan, 2026 will be year where I can finally make a real dedicated home cinema/theater a realty… fingers crossed

Thanks for the information and good luck with the home cinema/theater! I live in a townhouse and the lowest level is dedicated to a home theater. I’ve got a 7.1 all B&W speaker setup with a pre/pro, 1200 watt McIntosh 1201 mono amps for the front L&R, Bryston amplification for the other five channels, B&W Nautilus 801s, B&W HTM-1 in tiger eye as the center, some B&W 801 series 3 for the back and some B&W HTM-2s for the side channel. 120" screen illuminated by a Sony VPL-VW885ES 4k projector. Old stuff for sure but I like it.

Dolby is still very much alive…
