I just updated a Dell T340 from PVE7 to 8. I went through all the pve7to8 --full checks and simply followed the documented procedure. I also installed systemd-boot per the docs as I am indeed running UEFI on ZFS. I can still boot into 5.15.143-1. pve7to8 --full still shows as clean with the...

I am trying to create a VM to run NUT. On the physical machine I also have a USB Bluetooth adapter I pass-through to another VM and this works perfectly. For whatever reason the UPS is not recognized in the VM. I have rebooted the entire host and no luck. NUT server acpi: 1 agent...

When creating a sync job, is there a way to *except* items from being replicated? I have a replica where I want to replicate everything except one host. The docs make it sound like group-filter is an include only filter but I'm hoping there is an "everything except" filter possibility.

I woke up today with an odd cascade of events. First, one node of a cluster showed gray question marks for all objects. Interestingly enough the node showing all gray was also the one whose web console I was connected to. I rebooted the node and this issue resolved itself. Next, one LXC...

It appears somewhere between 2.2.1-1 and 2.2.4-1 the output formatting changed. Specifically previously running a cron with proxmox-backup-client> /dev/null gave no output to cron. Now cron is picking up the output of proxmox-backup-client as it appears it shows as an error and/or not going to...

I have an LXC container where I want to decouple the rootfs and a bind mount. I want to be able to backup, restore, and snapshot the rootfs completely separate from the bind mount. The bind mount I will then manage separately. The reasons being * The bind mount is huge. Backups via PBS take...

I am trying to map a ZFS dataset into an LXC. The dataset is a PBS data set I am migrating from bare metal to LXC if that matters. I have read the docs here and there are a few assumptions that I am not understanding. In that article it talks about user ID 1005. Is that a real user? Like I...

My PBS server is a running a huge number of "reader" jobs. They started at 13:00 today and I don't really have any idea what they are. Verification jobs are run hours earlier and all jobs show as OK. Any ideas what these jobs are? Example: 2022-03-29T13:39:22-04:00: starting new backup reader...

I have a situation where a "test" cluster moved to production out from under me and I need to get a few of the nodes proper IPs. I have a read a few threads here that seem to make it sound easy, but I am getting close to making a big mess. The one thread (this one) said to edit...

As the title says, when I change the root password of the PBS server, all nodes lose access to the data store. When I open the datastore in the data center settings of PVE, the password seems to not be able to be changed. I am missing something as I don't understand how the root password is...

I installed PVE on a disk, its 120GB. I want to move the boot disk to (2) SSDs in a ZFS mirror that are 500GB. I'm wondering if this will work. Boot to live CD dd old boot disk to new boot disk Boot on new boot disk Add additional boot disk as mirror Will this work? Then, will the rest of the...

It occurs to me that I may be wasting RAM due the fact that there are two caches at play. There is the ARC at the Proxmox layer. Then, my VMs have a kernel buffer/page cache caching reads for whatever file system they use … ext4, XFS, etc. Does anyone disable the page cache within their VMs...

Just as the title says, I rebooted today to apply a new kernel and my box gets stuck forever during boot at the “Import ZFS pools by cache file” step. I run ZFS for my boot disk too. I have seen a few articles on how to fix the issue - assuming I can get into the OS. Is there a way to “safe...

No matter what I do can't get my drives working at USB3 speeds. Everything looks right, so I am hoping some other eyes can give me some hints. # lsusb Bus 004 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root...

I am troubleshooting a disk that has realtively horrible performace and I am curious... does Proxmox Backup write using sync or async? As if it's sync, I probably need a separate ZIL or to forget about ZFS. If async, well... I keep digging.

I am not a smart person. I tweaked ZFS via /etc/modprobe.d/zfs.conf (specifically options zfs l2arc_noprefetch=0), ran 'update-initramfs -u' and I must have screwed something up in zfs.conf. The root file system is ZFS and now the box won't boot. Is there a way to fix this and ignore my fat...
