Testing ZFS with XCP-ng
-
Does this issue also have a role if you run glusterfs on top of zfs?
Or is it just directly on zfs.Because i would want to runs glusterfs on top of zfs on a spearate server, and use glusterfs driver to connect to it.
Do i also have this issue then?

@nraynaud I just tested with an up-to-date XCP-ng 7.5 host, same failure
# yum info vhd-tool Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Installed Packages Name : vhd-tool Arch : x86_64 Version : 0.20.0 Release : 4.3.xcp.el7.centos Size : 40 M Repo : installed From repo : xcp-ng-updates Summary : Command-line tools for manipulating and streaming .vhd format files URL : https://github.com/xapi-project/vhd-tool License : LGPL+linking exception Description : Simple command-line tools for manipulating and streaming .vhd format file. -
I am till on the issue, the subject is way deeper than expected.

Hello everybody! Newbie here, just 24h of xcp use, I was trying set Raid 10, but xcp only support Raid 1, so I'm trying now to set raidz, like on the document, I'm using 4 disks (500gb each), but I want to do Raid on this 4 disks (sda,sdb,sdc,sdd), so I can't? Need to be 6 disks? 2 raid 1 with xcp, and 4 raidz for other things?

Hi,
There is 2 different things:
- soft RAID 1 support during install, using
mdadm(the standard Linux software RAID mechanism) - ZFS support for storage repositories (where you store your VM disks)
Regarding your use case, it depends. You can choose to install XCP-ng system without RAID and use only one disk, and the rest for ZFS SR. Or RAID1 for XCP-ng system, and the left disks for ZFS.

Just to solve a doubt.... there is no way to install xcp-ng on software RAID 10, right? -
