Planning Proxmox VE 5.1: Ceph Luminous, Kernel 4.13, latest ZFS, LXC 2.1

DerDanilo said:
Proxmox should also have something similar to Heat/Terraform/ etc if it starts supporting cloud-init.

Suggestions
Why not use OpenStack to do real cloud computing? Proxmox is nice, even for bigger infrastructure projects. But for real cloud computing it's a different story. Have a look here. Mention my name when you get in contact with sales.

Cloudinit is not only for "cloud" computing. It is for automation of configuration of virtual machine and providing of metadata inside VM.
If you do it manually - you live in the past.
If Proxmox willing to be modern enough it should support Cloudinit(any way, link-local api or CD or whatever).
Proxmox already have good enough API and is supported by variety of tools like salt-cloud and so on.
 
Alright so I've upgraded from:

Code: 
proxmox-ve: 5.0-23 (running kernel: 4.10.17-3-pve)

novnc-pve: 0.6-4
smartmontools: 6.5+svn4324-1
zfsutils-linux: 0.6.5.11-pve18~bpo90

to the latest pvetest.

The upgrade went well and without a problem. After booting back up I had to
Code: 
zpool upgrade rpool
to update my pool and now it's seems to be working fine so far.

I have a couple of questions:

1. Will I be able to upgrade to the official 5.1 release from pvetest ?
2. I was under the impression that ZFS 0.7.2 would bring a big difference in performance based on other forum thread from other people. It seems my performance is still not where it should be.

I'm using an LSI 9211 and SSDs for the ZIL as seen here:

All ZFS setting are mainly default except the import by id instead of /dev/sdX.

Using pgbench in an LXC container running postgres resulted in what seems like low tps:

Code: 
postgres@dev-dbtst-1:/root$ pgbench -c 16 -j 8 -T 60 bench
starting vacuum...end.
transaction type: <builtin: TPC-B (sort of)>
scaling factor: 1
query mode: simple
number of clients: 16
number of threads: 8
duration: 60 s
number of transactions actually processed: 23487
latency average = 40.907 ms
tps = 391.131788 (including connections establishing)
tps = 391.239537 (excluding connections establishing)

Anything I could tweak/check to increase performance ?

In the meantime I will benchmark using real world performance as some suggest because from what they say you can't really use benchmarking tool for ZFS

Thanks for your work !

We just uploaded a bunch of new packages to our pvetest repository (for testing only), including zfs 0.7.2 and pve-kernel-4.13.4-1-pve

waiting for feedback!

@martin thank for notifying !

ceph still not runs with rdma enabled
 
Hi,
so I upgraded to ZFS 0.7.2 (added pvetest repo and launched apt-get upgrade) and now none of my VMs start (CTs aren't affected) with error that the disks are missing, because folder /dev/zvol just doesn't exist - the symlinks aren't there. /dev/zd* devices are visible. Some logs:

please open up a new thread so we can follow up there!

suggested next steps would be
- test latest vanilla 4.13 kernel
- test latest vanilla 4.14 RC kernel
(e.g. from http://kernel.ubuntu.com/~kernel-ppa/mainline/ )

if neither of those work, testing vanilla (not latest) 4.13, 4.12 and 4.11 would be the next steps

What do you mean you 'had to' update the pool? Wasn't it running correctly without the pool upgrade?
Click to expand...

Yes it was booting and running correctly but giving me the following warning:
Code: 
status: Some supported features are not enabled on the pool. The pool can
        still be used, but some features are unavailable.
So to get all the new features from 0.7 I had to upgrade the pool
 
After upgrade from test repo:

error: no such device: ff7652jfegfhgef.
error: unknow filesystem.
entering rescue mode ...

Hello.
Tell me, until the end of the month you plan to release a new release as announced?
We need to make a new cluster and would like to do it right away on the new version.
Thank you.

that pools need a manual upgrade to enable (and/or activate) new features is intentional - you should only do it once you know you no longer need to be able to import that pool using an older ZFS version lacking those features. it is ZFS's variant of versioning, since there are three diverging open implementations matching based on a minimum version number is not really feasible, so each feature that affects compatibility gets a flag ;)

could you check the log of ZED ("journalctl -b -u zfs-zed") and attempt to restart it ("systemctl restart zfs-zed")?
 
Just a general improvement recommendation but shouldn't the install create the pool by disk ID instead of /dev/sdX as per the ZOL best practice recommendation. As of now we need to select ZFS Raid 1 on install, change default to use the ID, reboot, add new disks, partition them and then add them to the pool to then convert to RAID 10 which could be all done by the install.
