DS1819+ with a 2.5GbE mod is finally nearly done doubling storage capacity! (sh.itjust.works)

Nice. I have the same model, I bought a used half height sfp+ Intel x52 from ebay*

It's worked like a charm

[–] Sixtyforce@sh.itjust.works 2 points 1 day ago

Oh those are pretty cheap, nice find.

Have you set the raid resync option to "recommended" or "faster"? That setting makes a significant difference.

Also ... you seem to be missing some storage. 8x 16 TB in SHR-1 should give you 101.8 TiB total ... but you only have 94.5? Where is the rest?

I did set it to "faster" yeah. It's not slower than expected, it's just novel to me how long it takes lol.

You're right about storage space but I'm not sure why yet. Some of it will be Btrfs overhead according to web searches. This NAS model I think has some limitation of 108 TiB max pool size, but I'm below that so...idk yet. Plus others said that limitation was if you were on stock 4 gigs of RAM. Mine has 32, it's doing more than just storing files but it's still over kill. Was just on steep discount.

Maybe I'll be able to expand the volume again once it's done the final scrubbing?

That's strange, but none of that should matter. I'm getting the exact value from the raid calculator:

And I'm actually hitting the 108 TB limit, but that's only for the volume, the storage pool can be larger. I've also upgraded my RAM.

Okay huh. I'll report back if anything interesting comes up once it's done.

edit: it worked itself out, nothing interesting haha:

Oooh nice- I have one of these too, but haven’t put in faster Ethernet yet. I’m gonna wait until all my network equipment gets a bump first.

The card you put in- is it the one that’s paired with the ssd cache card or something else?

[–] Sixtyforce@sh.itjust.works 3 points 2 days ago (1 children)

SSD cache wouldn't be useful I think. I'm under the impression at least I wouldn't see any faster transfer speeds, since the cache is really only effective for accessing the same small amount of data repeatedly like a web server. I'm rarely if ever doing that. So I saved some money and went to github:

I'm using a UGREEN USB adapter to get 2.5. Almost zero issues, except I have make sure to update the driver before DSM updates. I've had instability the one time I updated DSM first.

I’m on the same page with you about cache. Thanks for the tip though, I’m gonna look into this!!
