I get the part about no real numbers, thanks. CPU wise it will be fine, CPU is mostly idle right now. Memory, well, my VMs amount to up to about 20GB so as I said I have about 8GB free for ARc and the rest is buffer. I've looked a bit into synchronous writes found a few articles like this one...

I've got a budget server with a Intel Xeon E3 1245v2 CPU and 2x2TB HDs 7200RPM with a HW Raid controller (devices are mirrored) and I think 512MB cache on the RAID controller. The server has 32GB RAM Performance is good and the server is mostly idle and has plenty of resources. I have about 5...

Would you mind elaborating a bit? Do you mean that HW raid is supposed to be faster or that the test is skewed?

Thanks, I must have somehow missed that as it answers all my questions.

@RobFantini: its a Proxmox 4.2 installation using zfs as root so Linux it would be. So I have been reading and seeing the advice to properly plan the layout so one can do atomic snapshots for separate data and was wondering if this is feasible: I'd like to have snapshots of - the main...

So the current situation is to follow the wiki for Proxmox 1? => https://pve.proxmox.com/wiki/Backup_-_Restore_-_Live_Migration or is there any newer documentation available? In my case I don't care about online/offline migration I just need to get about 5 LXCs and 1 KVM from the Proxmox...

as far as I can see it also says to edit: /etc/modprobe.d/zfs.conf with the same values that is.

Thanks for all the feedback, I'm still reading up and will start playing around with znapzend in a few days so @RobFantini any notes would be appreciated. What was new to me was that I can send snapshots to any mounted remote FS:

getting different values by different tools for my swap partition: root@jeeves:~# swapon NAME TYPE SIZE USED PRIO /dev/zd0 partition 4G 0B -1 root@jeeves:~# fdisk -l /dev/zd0 Disk /dev/zd0: 32 GiB, 34359738368 bytes, 67108864 sectors Units: sectors of 1 * 512 = 512 bytes Sector...

this solution did not survive a reboot. :-/

editing: /sys/module/zfs/parameters/zfs_arc_max and inserting 8589934592 has done the trick. is this a viable solution? is the wiki outdated?

Freshly installed Proxmox 4.2 with a 2 HD mirror using ZFS for root I'm following this instruction: https://pve.proxmox.com/wiki/Storage:_ZFS#Limit_ZFS_memory_usage edited: /etc/modprobe.d/zfs.conf inserted: options zfs zfs_arc_max=8589934592 ran: update-initramfs -u rebooted arcstat.py...

Ahhh, having a blonde moment. of course uninstalling app proxmox related stuff should work :-) And you're right about the installation length but I'm using soyoustart and to avoid using their proxmox template, I had to boot into rescue mode, then run the installation via qemu :-/

Does anyone use any of these 3 tools to store snapshots remotely? Happy? To me it feels like pve-zsync is the newest with the least features but then its developed by the Proxmox team so yeah, just looking for what other people are using. https://github.com/oetiker/znapzend...

I'm testing a move to a new Proxmox server and have messed up moving old config files around. Is there a way to "reset" Proxmox into a state as if it was a fresh install? I'd rather avoid the lengthy process of reinstalling.

so the wiki is outdated :-/ any idea about the swap? I tried: zfs list NAME USED AVAIL REFER MOUNTPOINT rpool 5.01G 2.63T 96K /rpool rpool/ROOT 778M 2.63T 96K /rpool/ROOT rpool/ROOT/pve-1 778M 2.63T 778M / rpool/data 96K 2.63T...

Managed to become totally confused: I installed Proxmox 4.2 onto a mirror using zfs for root. I then followed the instructions here: https://pve.proxmox.com/wiki/ZFS#Adding_ZFS_root_file-system_as_storage_with_Plugin and then when I check as explained on that same page: root@jeeves:~# cat...

:-) thanks! Another lesson learnt!

OK, looks like I wasn't clear enough :-) The download link looks somethign like this so I couldn't get wget to work: http://www.proxmox.com/en/downloads?task=callelement&format=raw&item_id=188&element=f85c494b-2b32-4109-b8c1-083cca2b7db6&method=download&args[0]=8974fa38125a347c7eb19965997f99b9...

Sorry for the dumb question but I need a direct link or some other way to download the ISO via command line.
