Run lvscan to see if there are any active logical volumes. If there are run vgchange <group name> -an
to deactivate all logical volumes. Now try to stop the array.

RE: An updated installer for XCP-ng 7.5.0
@frank-s Hello again. My issue is resolved. I was using used disks which had previously been used with mdadm. Although I applied "mdadm --zero-superblock" to every partition and the device itself before deleting the partition tables and dd zeroed the first 50 Gigs of the drives, the installer didn't like it. Maybe I should also have zeroed the end of the drive??? Anyway I zeroed out the entire drive (both of them) with dd and the installer worked like a charm. I also tested upgrade which also worked flawlessly.
Thank you for the great work you are doing. Over the years I have spent many many hours loading xenserver with bootable raid. This is going to make life so much easier... -
RE: Install Plugins XO from sources
@Danp Thanks for pointing me in the right direction. I was following an older howto where --global was not specified. That was my first problem - now fixed!
Second problem was that I had installed into the root directory of Centos7 so the paths for creating the links were different. Once I had found the correct paths and created the links all was good.
Thanks again.
Frank.

Install Plugins XO from sources
I just installed XO from sources - latest edition. I have tried to find instructions how to install transport-email and backup-reports plugins but nothing I find seems to work. Could someone point me to a clear set of instructions please?
Thank you. -

RE: An updated installer for XCP-ng 7.5.0
@olivierlambert
I wasn't suggesting that the installer should do raid 10 necessarily. For XCP-NG itself raid 1 is sufficient. Just suggesting that the partitions of the installation could each be a different raid 1 set rather that simply doing raid 1 on a whole disk basis. If the end user chose to have the installer create local storage it could be just raid1 on another (big) partition. For those who want improved performance however there is the possibility to manually create raid 10 local storage post install.
What is wireframe? (I am not a developer). -
RE: An updated installer for XCP-ng 7.5.0
@olivierlambert
Glad to be of help. The new raid installer is a really good thing and I am using it now on two servers. The downside, however, is that it uses whole disk raid. If it used partition based raid1 then if XCP-NG were installed without local storage repo, it would be possible (after installation) to manually create raid 10 for the storage. With mdadm this could be done with three or more disks. So at that point all the installation partitions would be raid1 with all disk partitions as members but the bulk of each disk (assuming large disks) would be left unused for raid 10 - faster local storage. Would that be an over complicated change to the installer or is this a possibility? -

Probably that would work or as an alternative use dd to zero the first 45GiB of each disk shouldn't take too long. I was not pressed for time and had other things to do so I just zeroed the disks entirely after which setup was flawless. -

Hmmm. It might have been 0.9 as it was for boot partition. It wasn't whole disk raid though. Each partition was a different raid set. -

@olivierlambert
I did that Olivier but for me it didn't work. That's why I zeroed both disks entirely. Worth a try though as it doesn't take long.
