How have you tried to connect to the pfSense router? If you want to access the web interface, you need to allow this in the firewall / port forwarding configuration in pfSense. The web interface is not accessible for the WAN interface per default in pfSense for security reasons. But it may be...

I have a bridge vmbr1 with the PVE host and some VMs attached to it. The host uses shorewall to configure iptables. Access from the internal bridge to the public zone is configured by policy. There is masquerading enabled for the public bridge vmbr0 for the internal network. I can access the...

You can't give an IP address to a VM, only to an interface. And that has to be done on the guest. But I don't understand how your pfSense VM can successfully act as a router, if it is only connected to vmbr0 and the second bridge vmbr1 is unconfigured. You probably want to configure your vmbr1...

The server is part of our rented infrastructure. Unfortunately I am not allowed to flash alternate firmwares or swap or extend the hardware. I don't even have physical access to the machine. I have two identical servers of this type and they were running for over 18 months very well until one...

Hi Fabian, the controller is a 02:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 2108 [Liberator] (rev 05) which does not support real JBOD, but there is a mode that creates RAID 0 vDevs for every attached disk. I guess you are right when blaming the controller for this. After...

I received the hint that grub-install and even booting from the rpool does not work while the disk replacing is in progress. And in fact, after the resilvering finished I did the mount / chroot again and grub-install worked on all 15 disks without errors. Even 'grub-probe /' returns 'zfs' now...

I had one disk producing read errors in my 15 disk ZFS raid-z2 pool and replaced it offline. Trying to boot the system ended in grub rescue mode: error: no such device: <hex string>. Entering rescue mode... I booted with sysresccd+zfs and was able to import the pool with zpool import -o...

This helped me as well. Seems my controller takes a few more seconds to intitialize all 10 disks. 5 seconds for both options were enough in my case. Thank you very much!

Thank you very much! I'm still not sure why the grub-install fails for me. But I can live with that since the system is running fine for now. I'll dig into that if I have a scheduled downtime.

Apart from the disk size, my layout looks exactly like yours: # fdisk /dev/sdb Welcome to fdisk (util-linux 2.25.2). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Command (m for help): p Disk /dev/sdb: 5,5 TiB, 6001175126016...

I just noticed that /boot/ is just a folder on my root zfs volume, so there's no special partition for grub. Maybe my grub-install is not aware of ZFS?

I should have found this thread earlier: I had the same situation (one disk in my rpool was dying) but I replaced the disk without step 2 (initialize disk with GPT from the WebUI). I directly cloned the partition table with sgdisk, randomized the guids and did a "zpool replace rpool old new"...

Great. So if anyone has a background on this (Proxmox Staff?): It would be interesting to know what the reason was behind this issue. I can't find anything related to this in the release notes.

Oh that's good news! So you did upgrade to PVE 5.1 but did not upgrade your virtIO drivers, correct?

Ok something is going on: On my test system (software stack is the same as on my production system, one Windows Server 1016 has been cloned to the test system to be able to analyze this issue) I updated the system to the latest version with (upgrade / dist-upgrade, now PVE 5.1.36) and then I...

Since you are running ZFS it should be easy to create a snapshot and send / receive the snapshot to a test VM on your PVE 4.4 host without any down time. At least if you're running ZFS on the PVE 4.4 host as well and you have some spare storage left there to create the VM. It would be really...

Have you checked if the same VM (exact clone) from the PVE 5.0 host running fine on 4.4? If this is the case I would like to downgrade my hosts to PVE 4.4 since IDE runs stable but the disk performance is relatively poor then.

I had situations where all ram and even swap was consumed and the host was locking up. So the whole machine was out of memory and unable to fulfill requests. In my case I had forgotten to limit the ZFS cache on one of my servers. That's why i asked you if you're using ZFS. But for you there...

Just guessing: Are you using ZFS?

Thank you! I had to download one additional library "libhogweed2" but then it installed fine. I rebooted the host after the installation was done. But: Still the same issue!
