I want to try it on a new a new node (fresh installed, and not upgraded from 7.4) the node dont have kernel 5.15.116-1-pve installed is it the flow: proxmox-boot-tool kernel add 5.15.116-1-pve proxmox-boot-tool pin 5.15.116-1-pve proxmox-boot-tool refresh after reboot does the kernet...

i have stability issues on nodes with high cpu load and i would move back the to kernel was on 7.4. what is the best approach ? i am on pve 8.0.4 kernel 6.2.16-14

finally i have encounter a side affect, ceph mount inside the vm crashed, (umount and mount -a fixes it 95% of the times)

like this before on proxmox 7.4 i never had this issue, vm was exactly the same

sure here: both host and vm have mitigations=off in grub (error was more frequent before settings this configuration) my vm is host for high cpu load when the error occurs proxmox host: version: proxmox-ve: 8.0.2 (running kernel: 6.2.16-14-pve) pve-manager: 8.0.4 (running version...

should i set mitigations=off in the line: GRUB_CMDLINE_LINUX_DEFAULT="quiet mitigations=off" both on proxmox and vm is it enough?

i was investigation another issue, and left an open ssh conncetion to one of the vms: i have the same error: Message from syslogd@kube-node-11 at Sep 26 15:13:24 ... kernel:[426489.912429] watchdog: BUG: soft lockup - CPU#31 stuck for 22s! [Engine_Simulato:1069183] Message from...

Hey, so we've been using Proxmox in our small business since it was at version 3, and now we're on version 8. I don't know a ton about ESXi, but I've seen folks from other places slowly moving away from it and some hopping onto Proxmox. To be real, Proxmox isn't exactly plug-and-play, and...

i have some problem that occurs multiple times, Sep 26 13:51:19 pve-blade-212 pmxcfs[2455]: [status] notice: RRDC update error /var/lib/rrdcached/db/pve2-storage/pve-blade-211/cephfs-data: -1 Sep 26 13:51:19 pve-blade-212 pmxcfs[2455]: [status] notice: RRDC update error...

I use around 80% of the nodes in the cluster as a compute grid, i can freely disable the mitigation on them and gain some performance, what is the best approach? can it be done to a group of nodes (like based on name pattern) or it must be done one by one in grub ? do i need to do something...

If there are no intended support i assume i will not going to try it, tough few yeas ago on proxmox 4 i played the voting params because we had limited hardware, thanks for the fast response . closing the question

i have an existing cluster , and i want to add many more nodes (will store grid executor nodes on in) can i exclude those nodes to not be a part of the quorum in such case: node can join an active quorum, but will not be a part of the voting, (not needed to create the quorum) does something...

the issue is not related to the monitor. something regarding ceph: ceph status cluster: id: 8ebca482-f985-4e74-9ff8-35e03a1af15e health: HEALTH_OK services: mon: 3 daemons, quorum pve-srv2,pve-srv3,pve-srv4 (age 21h) mgr: pve-srv2(active, since 2d), standbys...

I am trying to upgrade to proxmox 8. after finish updating all nodes to 7.4-16, (and rebooted each node after install) and updating ceph from Pacific to Quincy i just noticed that in the ceph Performance tab i dont see traffic (i usually have around 300-6000MBS) with 1000+ IOPS systems are...

for unknown reason it resolved by itself, no issues for few hours.. ( i did not do anything ) , closing thread

i am trying to upgrade to proxmox 8. after finish updating all nodes to 7.4-16, (and rebooted each node after install) and updating ceph from Pacific to Quincy update when smooth without issues, after the update this issue occurred chrony is setup and running on all nodes across the...

Can the PBS backup network storage? for example i have proxmox cluster with ceph(proxmox based) and some other network storage mostly NFS based (external to proxmox) can PBS be used to back network storage?

proxmox 7.4 pbs 2.4-1 i have cluster of around 20 hosts, with dally schedule for backup of many vm\lxc to pbs i had an external (not proxmox) storage crash, that many vms\lxc had nfs mount to it. the backup caused most of the servers gui to hang, leaving most many lxc\vm in locked ) only...

What is the best approach? that will be easy to install and maintain for future upgrades currently on pve 7.4 and ceph 16.2.11 now have 4 vms (as testing,poc) but planning to grow to around 50 ( i prefer to do it once, then clone the node if it is possible) for perspective i have the...

same issue here, i am here from proxmox 4. and currently on 7.4 , :) was stable on all the upgrades so far .
