    KSM Memory sharing not working as expected on 6.2.x kernel

    We have been on the 5.13.x kernel because the entire 5.15 kernel is a mess imo. Live migration being a #1. I can't do any testing on 5.15.x for that reason.

    KSM Memory sharing not working as expected on 6.2.x kernel

    Yea these are CentOS7 guests that serve up extremely active app's. Probably a bit more active than any windows guest.

    Proxmox VE 8.0 released!

    KSM sharing is pretty much broken in the 6.2.x kernel and pve8. Leaving this here for more attention. https://forum.proxmox.com/threads/ksm-memory-sharing-not-working-as-expected-on-6-2-x-kernel.131082/

    KSM Memory sharing not working as expected on 6.2.x kernel

    Also worth mentioning I am having performance issues on the 6.2.x kernels without ksm enabled. We have pretty much lost 20-30% performance in the 6.2.x kernel's. These are heavy lifting CentOS7 LAMP servers that have no issues on the 5.13 and 5.15 kernel (Besides live migration on the 5.15.x...

    KSM Memory sharing not working as expected on 6.2.x kernel

    Yikes, 5.15 kernel is a mess to. Live migration between different CPU's and identical CPU's is pretty much broken all together. Looks like we are going back to thee 5.13 kernel as nothing has been stable in 6-12 months.

    KSM Memory sharing not working as expected on 6.2.x kernel

    Hey all. I have a 7 node cluster with roughly 600 CentOS7 VM's running on it. Typically average anywere from 150-500G in KSM memory sharing. After moving to the 6.2.x kernel on 2 of the 7 front ends those 2 front ends are barely using any KSM sharing. Front end with 6.2.x Front end with...

    Disk Migrations with io_uring

    Getting this trying to move a disk. Moving disks from Ceph to LVM iscsi storage. What I don't understand is all the disks on the LVM iscsi storage that are in place now are using aio=io_uring by default. So if aio=io_uring is bad for this disk type, then why is it default when creating a...

    [SOLVED] Physical volume on other hosts

    I have some iscsi based storage with LVM ontop. Introduced a new lun this morning to all 7 nodes. On one of the hosts I created a physical volume and volume group on mpath6. Iscsi looks good and so does multipath on all the hosts. Each host has the following. mpath6...

    Install with no LVM-Thin

    Maxvz 0 was a great idea. Then I simply add the pve VG as LVM storage and we are in business.

    [SOLVED] Odd RBD Feature

    I am using a project called Benji. Benji doesn't like the operations feature. To work around this I used the proxmox disk move feature to move the 2 disks to other storage, then back to Ceph. Operations feature was gone after that and all has been solid. No idea how 2 of 600 RBD's had that...

    Opt-in Linux 6.2 Kernel for Proxmox VE 7.x available

    Im still fighting performance issues. I have found stop/start only works for a few days. These are very active CentOS7 apache servers, but performance is night and day on the 5.15 kernels.

    Skip External VM's on Backup

    That makes sense. So I guess the question is, why didn't the backup run? As you can see prox1 started its backup on Sunday at 12am, prox2 is no were to be seen. Backup job has Node: set to All
