    Losing my mind with Coral (gasket-dkms)

    I followed the steps here (similar to the ones on several Proxmox forums) and was able to get Coral mini PCie working. Couple of months ago I rebooted and it hasn't worked since. I have tried removing gasket-dkms, rebuilding, and reinstalling several times. I ordered a new Coral and tried with...

    NFS backup errors only with LXCs

    Hello all, I get errors with PVE v7 & v8 when I use NFS (TrueNAS) to back up any LXC instances. I do not get errors with VMs. When I enable SMB shares on the same NFS sharepoint, LXCs will backup without error. Does anyone have any insight into this issue? ERROR: Backup of VM 303 failed -...

    TrueNAS VM, autofs mount, dependent LXCs?

    I'm running Proxmox VE 8.2.7. I have a TrueNAS Core VM, and a few of my unprivileged LXCs access an NFS share provided by the TrueNAS VM via a bind mount. The solution I ended up with is using autofs to mount the TrueNAS VM's share to the Proxmox host and then bind mount that share to the...

    [SOLVED] LXC container snapshot problem

    Dear Proxmox community, I run PVE 8.2.7 installed on Debian 12 (as I wanted to have a full disk encryption via Secure Boot) with encrypted ZFS pool. Then I created a dataset with some custom attributes (compression, quotas, refQuotas) and added it via GUI - Datacenter -> Storage -> Add ->...

    LXC container networking is unusably slow and unstable

    Starting today, any new LXC containers I make have terrible network performance. Any downloads I make start out full speed, and then over the next 30 seconds they peter out to nothing and eventually time out. Example download on the PVE host: root@nuc13:~# wget...

    Shrink BTRFS LXC container?

    By mistake, I expanded my LXC container which is located on a BTRFS file system far beyond what I intended (I put in 10000 GB). But now I don't know how to shrink it. All the documentation online assume ext4 or ZFS. Any ideas? Update: I fixed it! First, I changed the size of the container in...

    [TUTORIAL] How to Make Fstrim Run More Often in LXC Containers and Linux VMs + the Host (for GRUB and Systemd Proxmox VE Installations)

    This is a tutorial on how to make fstrim run more often or on days that you wish. This could be handy if you have stuff continuously writing to the drives which then later gets deleted, which would cause it to create a large amount of unused data. For example, I have a Minecraft server running...

    ZFS -> ZFS volume migration seemingly doing 1k writes?

    Hi, I'm migrating some large LXC containers from one ZFS array to another and I'm noticing some odd behavior. It seems that for some reason, whatever system that handles LXC migrations is writing the data in 1k chunks... I mean, credit to ZFS for managing nearly 140k 1kB IOPS on spinning rust...

    Any news on lxc online migration?

    It's been more than 2 years now since I last asked about the status report of online migration of containers. Oh, and got no answer, so it's been 5 years since I have heard anything about this from you guys. Would be nice to know that at least you keep in mind that we're right here waiting...
