you can tune this /etc/ksmtuned.conf # KSM_THRES_COEF: Decimal percentage of free RAM # If free memory is less than this percentage KSM will be activated # KSM_THRES_COEF=20 # KSM_THRES_CONST: Bytes # If free memory is less than this number KSM will be activated # KSM_THRES_CONST=2048 ----- Mail original ----- De: "Jonathan Schaeffer" <[email protected]> À: [email protected] Envoyé: Mardi 8 Janvier 2013 12:47:56 Objet: [PVE-User] KSM turning off automagically Hi (again) all. I saw a strange behaviour on my proxmox nodes. KSM was turned off, so I tried to enable it : # echo 1 > /sys/kernel/mm/ksm/run after a few seconds, the file is at 0 again. Is there a reason for this ? Any idea what happens ? regards, jonathan # pveversion -v pve-manager: 2.2-32 (pve-manager/2.2/3089a616) running kernel: 2.6.32-17-pve proxmox-ve-2.6.32: 2.2-83 pve-kernel-2.6.32-11-pve: 2.6.32-66 pve-kernel-2.6.32-17-pve: 2.6.32-83 lvm2: 2.02.95-1pve2 clvm: 2.02.95-1pve2 corosync-pve: 1.4.4-1 openais-pve: 1.1.4-2 libqb: 0.10.1-2 redhat-cluster-pve: 3.1.93-2 resource-agents-pve: 3.9.2-3 fence-agents-pve: 3.1.9-1 pve-cluster: 1.0-34 qemu-server: 2.0-71 pve-firmware: 1.0-21 libpve-common-perl: 1.0-41 libpve-access-control: 1.0-25 libpve-storage-perl: 2.0-36 vncterm: 1.0-3 vzctl: 4.0-1pve2 vzprocps: 2.0.11-2 vzquota: 3.1-1 pve-qemu-kvm: 1.3-10 ksm-control-daemon: 1.1-1 -- IUEM - Service Informatique rue Dumont D'Urville Technopôle Brest-Iroise 29280 Plouzané France tel: +33 2 98 49 87 94 _______________________________________________ pve-user mailing list [email protected] http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user _______________________________________________ pve-user mailing list [email protected] http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user
