Hi thanks for your reply! I did replace the powersupply as a test, unfortunately this wasn't the issue as problems remained. Then I updated the bios which included the agesa. Unfortunately that also didn't solve it. Disabling the C-states dit help as in the crashes where not immediate but took a...

Ok finally fixed the freezing, I completely disabled the Precision Boost Overdrive (PBO) so CPU is fixed to 3600Mhz. Now everything is stable for a while now. So it seems something is broken in later kernel updates?

Looking on the internet and here in the forum, it almost looks like something has changed in the latest kernels in the C states which don't work well with Ryzen. As mentioned above we had a stable system for over 6 years and this week it started freezing. It seems that disabling everything above...

I had the same and changed all C state related items in the bios. (disabled them) And added this to Grub and I don't want to jinx it, but its steady working now for 6 hours... GRUB_CMDLINE_LINUX_DEFAULT="rcu_nocbs=0-15 processor.max_cstate=1"

I have a node that has been running for 6 years without any issues. Recently, it started freezing randomly every few minutes or hours. Hardware: Ryzen 3700X on Asrock X470D4U OS on SSD (ZFS mirror pool of 4 HDDs + 900P Optane) Symptoms / Attempts: Initially freezes occurred every ~5...

Problem is solved, there was a unconfigured test server of OPNSense running in the network which as a default apparently as a router advertisement on. (even if DHCP server is off) As soon as this was shutdown, it started working again.

Ah I see I removed HTTP and HTTPS here on this screenshot. They where on there and when added again, still doesn't work (for IPv6)

With the below firewall rules, the machine can contact ipv4 addresses without any issue. But for some reason ipv6 can't get through. (standard policy is drop in / drop out) When I enable the first 2 lines, Ipv6 has internet again. It does not seem to block anything in the logs, am I missing...

We have sanoid / syncoid running for managing snapshots and replicating them. Is it possible to show the snapshots taken in the snapshots overview from Proxmox?

Would a three-way mirror make more sense then RaidZ2 speed wise?

Hi I was thinking of building a small server for the office based on the new Ryzen processors (after they fixed the linux issue) Something like this, Ryzen 3900x 64GB ECC Ram Asrock Rack X470D4U Intel 905P drive as cache/slog 3x 10TB WD Red in RAID-Z2 I will be running a few VM's on them of...

Looking by the size they indicate at zfs list -t snapshot although I'm not sure if that measurement is correct as the same snapshot has a different size on the other side.

Hmm I think I see what is happening. Most if not all snapshots are very small, like 20MB. But then once a day there is a snapshot that is very big +2GB. It is syncing a range of snapshots so everything together is like 4GB. For the VM's even more. Now only to find out why some snapshots are...

In my case, I'm going from a RAIDz2 pool to a single remote disk. Different disks. But then still syncing 26MB or several GB, I can't imagine it could be clarified by type of disks.

yes I definitely understand what you are saying, although I don't think that is where this huge difference is coming from. You are right though source record size was set to 8k and the destination to 128k, so changed that now. Lets see if it helps ;)

I was hoping someone could help me clear something up. When making a ZFS snapshot and sending it offsite the sizes don't really look to be what they should be. What I mean is this, I made a snapshot and the size of the snapshot is 26.4M. When transferring this same snapshot with zfs send /...

Although trying to roll back snapshots made by FreeNAS can't be rolled back unless you disconnect the iSCSI target.

I have Proxmox working quite well with FreeNAS through this plugin. But for some reason I get a terrible performance for a windows VM. Netwerk speeds are ok at 1Gbit (tested both ways) Netwerk speeds are also ok from inside a VM Reading / Writing are also ok, local, from client and within a...

To answer my own question, add command="zfs get -o value -Hp available,used",no-agent-forwarding,no-port-forwarding,no-pty,no-user-rc,no-X11-forwarding ssh-rsa AAAA In the authorization_keys file before the key (until the ssh-rsa part offcourse)

with the ZFS over iSCSI you have to copy over the authorized keys file to your NAS. But this would mean the nodes have root access to my NAS machine, which I do not want. What is the command that they need to execute? I would like to limit the access to only that command. (I would like my...
