Seems like the "dd" processes are running niceness of 0 which can slow things down considerably on slower systems and/or when preclearing multiple disks at the same time. Running this on the dd processes seems to make a big difference in system responsiveness: renice -n 20 -p <pid> Would it be possible to have the plugin launch the dd processes using nice? Apologies if this has been suggested before. edit: Here's a one-liner to set niceness 20 (low cpu priority) on all currently running preclear jobs renice -n 20 -p $(ps aux | grep 'dd if=/dev/' | grep -v grep | awk '{print $2}') edit2: modified to catch preclear read operations too

edit: misread the issue, never mind

read-only filesystem is often just caused by an unclean shutdown. If you shutdown your server and put the USB stick in a Windows machine it should offer to repair the filesystem. edit: backup the unraid files before you do a repair

The DTSE9 model is still available though? Few USB 2.0 drive models would still be manufactured these days. For various reasons USB 3.0 thumb drives seem to be less reliable on average, which is another reason why you might want to have a few good quality spare USB 2.0 drives.

I just replaced my original USB drive from 2008, the only reason I did is because my 1GB drive needed manual intervention each upgrade due to space issues (need to remove the previous backup) If nothing else it may be worth having a quality spare on-hand. The Kingston DTSE9 is well regarded (not the G2 version).

Have you also swapped those 2 sticks for the other 2 sticks to make sure they are stable as well? Have you definitely confirmed in the BIOS that with 4 DIMMS populated they are running at 2666Mhz? Maybe I've misunderstood but you might have this the wrong way around. The platform / memory will run below it's rated maximum speed with no issues - the issue can arise where you're trying to run your DIMMs at too high a speed. In this case the limiting factor is the platform (not the memory) due to following factors: Number of DIMMs Single or dual rank DIMMs CPU architecture Even though 2666Mhz should be supported, you might find that you achieve stability by dropping this to 2333Mhz or lower. While not ideal, if this is stable it would confirm that your validated configuration isn't running as it should - you could then follow this up with Asrock re: possible BIOS fixes / RMAs. ps: memtests are worth running, but aren't necessarily going to show up every possible issue with memory stability in a running system - particularly in edge cases like this where the memory speed isn't the issue, but the platform itself. edit: I guess you can ignore the above if you're sticking with two DIMMs - though may be worth working out what the issue is anyway if you might want the extra memory in future (VMs, dockers, etc)

Just adding another vote for this feature

Any chance the iSCSI Target plugin could be modified to create thin-provisioned qcow2 files instead of raw? qemu-img create -f qcow2 file-path -o size=Size-in-MB,preallocation=metadata https://www.geekpills.com/operating-system/debian/ubuntu18-04/how-to-setup-iscsi-storage-server-on-ubuntu-18-04-lts

I'm going to be setting up something very similar soon. I'm going to be using sanoid/syncoid, but in "pull" mode: Pull mode - The backup "pulls" snapshots from the primary server Push mode - The primary server "pushes" snapshots to the backup server. Sanoid has a configuration template for "backup" mode, meaning that it won't be generating any snapshots, but will prune old snapshots as required. This should be applied to your backup server datasets. You're much more likely to get help with sanoid/syncoid as they are much more widely used.

You are unlikely to find this directly, but if you reach out to one of the sellers that flash LSI HBAs, you could ask if they would flash P16 for you. https://www.artofserver.com/ https://www.ebay.com/usr/theartofserver

I had problems with Resilio continuously rescanning a large dataset - by default it will attempt to rescan every 10 minutes. You can set how often Resilio will rescan here: https://help.resilio.com/hc/en-us/articles/205458185-Setting-how-often-Sync-should-check-for-file-changes- I ended up changing this to a week (604800 seconds) as in general Resilio should get notified of any new/changed files.

These can be really tricky to diagnose... Do you have enough memory that you could remove half of it? If still happening, swap for the other half? Can you turn these off for a few days? My general advice is to remove/turn things off that you can to try to isolate the problem.

You seem to have eth0 and eth1 bonded using LACP (802.3ad) - have you tried reverting to standard mode1 (active-passive) and non-LACP configured switch port/s? Bit of a stab in the dark, though much of the crash report seems to be network related.

It's a long-shot but you may want to try WinOF v5.50.54000 (the one that's allegedly for Server2019 only) Worked fine with Win10 LTSC (1809) and ConnectX-2

Try using mlxconfig to confirm SR-IOV is properly enabled on the card - step 3 here: https://mymellanox.force.com/mellanoxcommunity/s/article/howto-configure-sr-iov-for-connectx-3-with-kvm--infiniband-x Edit: You could probably follow the firmware update instructions in my post, but replace fw-ConnectX2-rel.mlx with fw-ConnectX3-rel.mlx I'm not sure if the format of the ini file is the same for ConnectX-3 though, ie this part: num_pfs = 1 total_vfs = 64 sriov_en = true Maybe export what's in the current config mstflint -d mtxxxxx_pci_cr0 dc > backup.ini What's in the [HCA] section? I did all this on a Windows machine, but there are Mellanox tools in unRAID Apps: Mellanox-Firmware-Tools Edit2: Some more bed-time reading for you! https://forums.servethehome.com/index.php?threads/how-to-enable-sr-iov-on-connectx-3.24321/

I should have been a dentist... ls -al /boot/config/plugins/unRAID6-ZFS/packages/unRAID6-ZFS/raw/bce53432ab6891f33cd2fd16a4621b66a0c9c2dd/packages/zfs-2.0.0-unRAID-6.9.1.x86_64.tgz do you have a file here now? If so, reboot. zfs Does this command work now?

Your answers aren't very clear Are you saying it was already correct or you updated the time and it's correct now? You keep asking what to do next, but without being specific about exactly what your current problem is or what you are trying to achieve.

Great, you should be able to installl/update other plugins now including unRAID itself, which I assume wasn't working previously. You might want to go to Settings / Date and Time and enable/set NTP server to keep your unRAID server time correct. 0.pool.ntp.org 1.pool.ntp.org

Reboot and the unRAID ZFS plugin should use the package you just downloaded. There's still some underlying issue to be solved though, or you will continue to have problems. It's possible this is due to the system time on your unRAID server being incorrect. What's the output of: date edit: If date is correct, what's the output of this: openssl s_client -showcerts -servername github.com -connect github.com:443

If still not working, does your unRAID machine have internet access? Try these to test ping 8.8.8.8 net lookup github.com

I can't reproduce this issue with 82599 or ConnectX-2 SR-IOV. Is your 82576 a dual-interface adapter? If so, you could potentially get around this by using SR-IOV on the second interface and br0/VMs on the first interface only?

On "plugins" tab, is "ZFS for unRAID 6" up to date? What's the output of this command? ls -alh /boot/config/plugins/unRAID6-ZFS/packages and this: cat /var/log/syslog | grep 'plugin:' Is your internet gateway running on unRAID? I have run in to issues where the required package can't be downloaded on boot (and hasn't been previously cached) You could try downloading the package manually and rebooting? cd /boot/config/plugins/unRAID6-ZFS/packages wget 'https://github.com/Steini1984/unRAID6-ZFS/raw/bce53432ab6891f33cd2fd16a4621b66a0c9c2dd/packages/zfs-2.0.0-unRAID-6.9.1.x86_64.tgz'
