  1. ZFS issues with disk images after reboot

    Just updated to latest Proxmox ( 7.2-11) and started having same issue. The command described above will fix the issue for this boot.
  2. Live migration network performance

    I believe the end speed depends on speed of the cpu single core and contents of memory. I could achieve around 25-30Gbit/s speeds over 100Gbe SFP links, no RDMA (directly connected on 3 node cluster) on AMD epyc 7401P (ceph as storage, so memory copy only). using jumbo frames might drop some...
  3. VM ZFS dataset consumes all available space

    Had the same problem on 5x8TB disk raidz2. 25% of space was lost. It would have been the same as having RAID10 instead (cost of one added drive not considered). It was default 8k volblocksize and 128k recordsize. If I used 64k volblocksize I got away with 10% of wasted space and bumping...
  4. add node that conatins vm's to cluster

    I think you are totally overthinking or not thinking at all. I did not say to rename scsi0. I said rename scsi0 storage name. It has your vm id. So like in my case I have id 1001 machine and like it to be 5001. So: 1) rename 1001.conf => 5001.conf 2) edit the config: scsi0...
  5. [SOLVED] ZFS partitions get rebuilt/activated by mdadm

    I am not interested in disabling auto assembly. I was interested disabling auto assembly for zd*. Since I can't think of way make negative glob ( can it be even done?) then I just ended matching for scsi and nvme devices. I have never been good at glob/regex. # by default (built-in), scan all...
  6. [SOLVED] ZFS partitions get rebuilt/activated by mdadm

    It's said even on proxmox documentation itself - you can test out proxmox cluster inside proxmox :). It's not uncommon to have these setups if there are some dev machines or migration clones from real world servers. I sometimes make test upgrade/reinstallation on proxmox and then dump the...
  7. add node that conatins vm's to cluster

    Under /etc/pve/qemu-server there are configs for vm's. If you want to change the id you can rename the files. root@phoenix:/etc/pve/qemu-server# ls -ll total 25 -rw-r----- 1 root www-data 392 Feb 22 01:39 1001.conf -rw-r----- 1 root www-data 445 Feb 22 01:39 1002.conf -rw-r----- 1 root www-data...
  8. add node that conatins vm's to cluster

    I believe you just described proxmox recommended way of doing it. Yes - you can backup and then restore to different ID. You can also clone the current vm and this way you get new clone with new id and can delete old one (if you have storage space). As a last resort you can edit .conf files to...
  9. [SOLVED] ZFS partitions get rebuilt/activated by mdadm

    I have a trouble where mdadm autoactivates zfs volumes from VM's. I would not like mdadm to touch anything from zfs volumes. I tried to search for it since it's more like debian problem, but could not filnd a solution. Probably a filter when loading mdadm module? root@elite:~# cat /proc/mdstat...
  10. ISO Upload Hangs pveproxy.service (>2GB)

    It's probably somewhat offtopic but why are we uploading stuff to /tmp to copy them over to some storage later instead of just copying directly to storage. I have hung the proxmox many times because of big image file and not enough room on /tmp folder. Also after uploading it will take...
  11. [SOLVED] Can I move VMs from Intel to AMD?

    Live migrating between Xeon(R) CPU D-1541 and AMD EPYC 7401 will randomly crash Centos 8 guest OS. Funny enough, it will not crash straight away. It just freezes guest few minutes after migration has ended. Reset of guest (or stop-start) will reboot and fix it. It won't crash openwrt 21.02.
  12. Ceph on Raid0

    AFAIk the leds only blink (activity) and will not show "dead" disks, because now it's HBA and does not monitor your disk statuses. You might still be able to call identify , but that's about it. You get led action at all? even for disk read-write? Was just hit reply then found this...
  13. Starting VM with RDP

    I depends how you have this set up. If it's in private network then I would make a simple tcp listener that will use proxmox api to check if machine is alive already. if not then it would trigger the guest startup using pve api. If machine is already in running state then it would just pass tcp...
  14. Easily remove old/unused PVE kernels on your Proxmox VE system (PVE Kernel Cleaner)

    Did not work on one of the boxes. Keeps looping around and not removing anything. Worked on my other nodes. Boot disk space used is critically full at 84% capacity (729M free) [-] Searching for old PVE kernels on your system... "pve-kernel-5.3.18-3-pve" has been added to the kernel remove...
  15. Ceph on Raid0

    It seems this is the guide: https://fohdeesha.com/docs/perc/ There also seems to be video info: https://www.youtube.com/watch?v=J82s_WYv3nU I have not done this on dell cards, but have done it Supermicro cards, that are same family LSI chips. All that said - supermicro cards are just easy to...
