Hi, My Unraid server keeps randomly hard freezing and I’m really struggling to work out why. Diagnostics zip attached. When it happens: Web UI dies SMB stops responding Docker containers stop responding SSH becomes unusable Need to hard reboot The latest freeze happened while I was using MusicBrainz Picard to retag/reorganise my music library over SMB. I was fortunate enough to grab an htop screenshot just before it completely died. It showed: load average over 600 very high smbd CPU usage high shfs usage RAM almost full Jellyfin ffmpeg processes active I originally thought Music Assistant was causing it because it had my music share added over SMB, but I removed that afterwards and it still froze again later. No obvious kernel panics or disk errors that I could see. Would appreciate if someone could take a look through the diagnostics and point me in the right direction. Thanks server.zip

Sorry, when you said "try writing to one or both and see if performance is better", I was assuming you meant the individual disks, which then I explained I can't write to the indervidual disks due to it being configured as a pool. I have tried again writing via SMB with turbo write enabled and I still get around 70Mb/s.

I've also tried enabling disk shares and running a write and read test that way and its the same speeds at 70Mb/s~ writes and the common factor is SMB.

Because its a pool I only have the one mount point so I have to write to both drives. If I DD to the drives since switching to raid 0 the speed is great at 600Mb/s~ root@Cobra:~# dd if=/dev/zero of=/mnt/user/Games-Windows/test.img bs=1G count=1 oflag=dsync 1+0 records in 1+0 records out 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 1.56801 s, 685 MB/s I think it must be something to do with SMB? as the drives speeds are fine and I have tested network throughput with iperf and that was fine too.

Sure, attached. Just to update I noticed the BTRFS was set to raid1, I've rebalanced to raid0 as its only games on this pool and the write speed now has gone up to 70Mb/s which is better, but would still expect this to be higher. cobra-diagnostics-20231005-0830.zip

Looks fine to me on 1GBPS?

I know they are not the best but I would still expect them to perform better than 30-40MB/s write being SSD's... I've tried copying a 10gb file and I get around the same speeds. I have enabled this but it hasn't improved the speeds unfortunately.

Hi, I've created a separate pool of two 2tb SSD's to store my steam library on using the default BTRFS file system, However after making sure the share is only using this cache pool and not the main array, its has really slow speeds of around 36MB/s write and 100MB/s read, I've checked my SMB settings and enabled multi channel but there has been no improvement. I'm fairly certain the problem is SMB as running a DD shows write speeds of 186MB/s ~# dd if=/dev/zero of=/mnt/user/Games-Windows/test.img bs=1G count=1 oflag=dsync 1+0 records in 1+0 records out 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 5.77645 s, 186 MB/s Is there anything I can do to improve these speeds over SMB?

I had the same issue. For me I couldn't have the user called "nextcloud" which was the same name as the database. I changed it to "nextcloud_user" and it worked.

Is it possible to run this if you don't have a GPU attached? I just want a steam client to run to just update games and nothing else.

This worked great for me. It looks like the sed to get the file name no longer works in the script, curl --fail --silent https://github.com/OpenVPN/easy-rsa/ | grep zip | grep archive | cut -d\" -f16 | cut -d\" -f1 | sed 's#^#https://github.com#g' | grep -v "sig" Is this plugin still being maintained?

I have a new RX5700XT and it would not work with UEFI enabled on the BIOS. It was also the same for my GTX 960.

@Skitals In your first post can you mention setting CSM to enable and booting via legacy rather that UEFI? I had major problems passing through a GPU until I enabled that and checked unraid to make sure I was in legacy mode and then everything worked.

Thanks for this write up, its been super helpful so far. I'm having problems passing the [AMD] Starship/Matisse HD Audio Controller to my windows 10 vm, it seems to completely crash unraid when I try to do this. Has anyone had any success in passing it through?
