Hi Lindsay, Could you post me the following results by private email (outputs of these commands)?
zpool status -v zpool get all zfs list zfs get all (needed 2 times for the system and data) arcstat.py Questions: did you turn on dedup on your pools? do you use any non-default zfs/zpool settings? how is your cpu load on normal and stressed (problematic) situation? is it true, the situation depends on uptime? For example usually the situation happens after 2 weeks? Or can you see any pattern when the bad situation happens? Hints without too much explanations: you can monitor your pool activity by the following command: zpool iostat -v 1 (a screenshot would be nice) do not turn on dedup. if you turned on -> recreate your pool from backup without dedup enabled the default memory usage of zfs is 50% of the physical RAM. Due to the interaction between the linux memory management and spl, the total used memory could be the double of the ARC size. In other words: plan your memory allocation: MEMORY_OF_ALLVM + 2 * ARC size probably it is much better to turn off swap, as the swap is on zfs: any problem on zfs will bring your computer down -> like performance if your system start to use swap, your system is underplanned (as I can see, this is not the case) try to find a pattern of your performance issue Best regards, István ----------------eredeti üzenet----------------- Feladó: "Lindsay Mathieson" Címzett: "Dietmar Maurer" diet...@proxmox.com CC: "ProxMox Users" Dátum: Mon, 17 Aug 2015 16:03:34 +1000 ---------------------------------------------------------- > > >Think I'll try reinstalling with EXT4 for the boot drive. > > >On 17 August 2015 at 14:50, Lindsay Mathieson lindsay.mathie...@gmail.com >lindsay.mathie...@gmail.com wrote: > > > > > > >On 17 August 2015 at 14:43, Dietmar Maurer diet...@proxmox.com >diet...@proxmox.com >wrote: > what kernel and zfs version do you run exactly? > > > >Free install, updated to latest from the pve-no-sub repos > >uname -r >3.10.0-11-pve > > >cat /var/log/dmesg | grep -E 'SPL:|ZFS:' >[ 17.384858] SPL: Loaded module v0.6.4-358_gaaf6ad2 >[ 17.449584] ZFS: Loaded module v0.6.4.1-1099_g7939064, ZFS pool version 5000, >ZFS >filesystem version 5 >[ 18.007733] SPL: using hostid 0xa8c00802 > > >-- > > >Lindsay > > > > > > >-- > >Lindsay > > >__________________________________________________ > > >_______________________________________________ >pve-user mailing list >pve-user@pve.proxmox.com >http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user > > > >
