Hey guys,
I have an HP ProLiant ML150 Gen9 and have been using UnRAID for a week or two now and am at my wits end.
When I first installed it, I found that the transfer speeds were abysmal. They were clocking at less than 1mb when transferring from my Windows PC to the share. I have 10k SAS drives so I didn't understand as they should be able to hit 6gb/s. I did not have a parity or cache drive set up so should have been copying straight to my drives.
Then I heard people saying that having a cache drive would speed this up, so I went out and bought a 256gig SSD and set that up as a cache drive. I still have no parity drive as I want to have the highest speeds possible atm. I'm not too concerned with losing my data as this machine is just for streaming media.
In this time I also swapped out most of my SAS drives for external harddrives as I was hitting my disk limit for my UnRAID licence, but these have been performing better than the SAS drives(but still slow).
The SSD made transfers quicker, but really it has just delayed the problem because the SSD fills up and then I have to wait an ungodly amount of time for the SSD to clear itself out - the transfers to the array are so goddamn slow. About 5mb/s.
In the process of getting to this point I wasn't paying attention (was up to 3am trying to figure it all out) and formatted my drives losing all my movies. It sucks but it's not the end of the world, I have my IMDB lists in Radarr so everything will be back eventually.
But now I have this problem where my machine is basically downloading 24/7 and transferring 24/7. Files are moving from cache to parity at an unbelievably slow rate and my machine is so bogged down that it takes minutes to load into the webui of any of my docker containers. Starting, stopping, updating and editing containers, unzipping files and navigating UnRAID also takes way more time while transferring out of the cache. My CPU is currently sitting at 40-60% overall load.
This has all made me think: how is this going to be viable going forward? I'm used to downloading many movies everyday to keep my library growing and I have up to 5 people streaming media remotely. If my machine takes a full 24 hours to move 230gigs to the array and I want to be able to download that much and maybe more every day (for example a full TV show) I just don't see UnRAID being a viable option.
Something just doesn't feel right! These speeds can't be normal! But I can't find anything online about how to fix it. I can't even find anyone having the same issue as me. People online are complaining about 50mb/s when i'm struggling to hit a tenth of that.
I have reconstruct write on, disks are in xfs mode. I have two 32gigs of ram and a 1gb/s network speed.
Please help me! This has been a nightmare
