Thank you again for the wealth of information.
Regarding the backup plan, that will be twofold: one copy on cold drives on site and another copy residing on several smaller QNAP units off site running RAID 6.
I was aware of the recommendation to not overfill ZFS, but always wondered whether...
V.interesting, thanks for the colour. We have 8-drive arrays populated with 12TB drives (EXT4, not ZFS), where the scrub takes about 20-22hrs. Anything less than 1-1.5 days I would view as tolerable - hoping for that to be the case with ZFS also...
PS. Great to know you never managed to max out...
Thanks Gea, super helpful!
It's great to know the RAM rule need not be observed religiously.
In your example of a videoserver, what would be the best way to optimise the raw pool performance? More vdevs with fewer drives in them (as opposed to fewev dvevs with more drives)?
Would the...
Thanks Gea. 2 days scrubbing/resilvering for a relatively full volume (80-90%) would not be too bad in our case. It would be twice as long as the current EXT4 system, but we could live with that.
Regarding the RAM, it occured to me that our set-up would be in clear breach of the old...
Hi all,
Your wisdom and experience would be highly appreciated with the following query.
I am setting up a 24-drive NAS (QNAP TS-h1283XU-RP). The hardware seems decent (Xeon E-2236 6-core 3.4 GHz, 128GB ECC RAM). The system volume will reside on an m.2 drive. For cold storage, there are 12...
