Cabbit

I'm having a strange issue. All my drives will spin down and stay spun down, despite applications and whatnot using them. This causes a cascading failure of the entire system. Everything becomes unresponsive, dockers start to malfunction and all my shares disappear. Only fix is to reboot the server. I'm not sure what the issue is, seems to be related to the most recent update of the plugin, as it's never done this before. Using Unraid 6.9.0 RC2 with spindown 0.85

Yep, it's cached

Awesome thanks, was able to reformat with 1MiB. However it didn't seem to improve the transfer speeds. What I meant was my computer transferring files over SMB to a share, not VM. My computer can iPerf to the server at a full 10G, but files are only transferring at 5-7Gbps. Might open a new thread then.

I'm having very similar issues - was going to make a new thread but I think we have the same problem. Using a 1TB NVME drive as cache and have another as a part of the array. Testing transfers on my gaming PC that also has an NVME drive. Writing to either the cache or directly to the array drive results in reads of 4Gbps and Writes of 7Gbps. I was on 6.8.3 and just upgraded to 6.9.0-beta25 - however this only made things worse. Dropping reads from 5 to 4gbps. A single stream iPerf yields around 8-9Gbps, two streams maxes it out fully (9-9.5gbps) My NVME drives are MBR 4K - I'm not really sure how to format them to 1MiB alignment. Any input on that would be awesome!
