iostat -kxz 5 /dev/sd? Please format your output with code tags.

1. I've though that I've set the record straight on the 940GB L2ARC in post #5, so you just repeat that to argue with me? :) 2. There is no 512 bytes/record. Usually Linux filesystems have 4K blocks, so that will be the minimum record size in the pool. 3. The L2ARC header size varies too (see...

You cannot compare ARC to slog (not ZIL) stating that "ARC RAM" is more important. Even if you have a huge amount of RAM, your sync writes will be written in sync (with sync=standard). Either this is done in a special area in the pool or on your slog (external device for ZIL). That is why it...

Add a /etc/modprobe.d/i915.conf with the following contents options i915 i915_enable_rc6=0 Then update-initramfs -k all -u reboot

Right. I feel stupid now. I usually use the top right menu in UI, not the contextual one.

BTW, "freeze" is KVM/QEMU suspend? I want a button for that for non-HA VMs :)

Live migrating, no, for sure. Restarting the VM on another node, yes.

Read above about big servers. 30 seconds is for my laptop. For a big memory Dell, 25 minutes is for "Configuring Memory" only. Then you add checks, PCIe devices init, OS startup, VMs startup.

Actually I was making fun of Proxmox's HA, not your issue. The concept of *High* Availability is not very compatible with 10-15 minutes of downtime because of a (planned) host reboot. Btw, you should try a BIG server reboot (we have a 1.5TB RAM machine) to find out that 15 minutes of reboot time...

Then we can call it HA* or Best-Effort Availability :)

No, you didn't understand. With fair scheduler, two containers at 100% will have very close to 50% of the host each. Without it, the results may be far away from 50%/each. Again, this scheduling makes sense in a resource (CPU) scarcity context. The fair scheduler will try to allocate fair CPU...

No. It is a "weight". You have 3 CTs: - cpu units 1000 - cpu units 2000 - cpu units 1000 First one will have 25% of CPU time, 2nd 50%, 3rd 25%. This applies relative to full load only. If the machine is idle, it doesn't matter. Think of them as a lottery. The more tickets you buy (cpu units)...

Incidentally, Safari on El Capitan works for me, but yes, there are all kinds of issues with various heavy-javascript sites in this version.

Tried to reproduce it on my side and I couldn't. I've copied ~800MB and the "cached" value stayed the same. I have "dir" type containers (on ZFS). Are you by chance have a loopback-mounted one (e.g. on ext4)?

from the host you can use pct enter <container id> Use top if htop shows all, although in my containers it doesn't.

The LVM layout and configuration is created by the installer. Why would you backup some partitioning information? Maybe you will need to restore to another hard-drive with a different size.

You make an archive of your / (after you shutdown all the services, like databases) excepting /proc/*, /sys/*, /run/* and import it in your LXC container. Worst case, you might need to fiddle with systemd. A better way to do it would be to mount the KVM disk inside the host and do the...

Your custom stuff is... custom handled. I was talking about backing up for a quick restore: install from iso, copy back the needed files (from /etc/pve/qemu/*.conf and /etc/pve/lxc/*.conf), the network configuration and you are done (again, assuming you have a separate backup or external storage...

If you backup your storage, /etc/pve folder and /etc/network/interfaces should be enough to put a new install up in no time.

@Ovidiu: do it in hypervisor. You cannot alter it inside LXC/OpenVZ.
