    In case anyone wonders how this played out. At the end of the day, I shutdown the host with the running workloads on it, kept it at BIOS boot so the 8.3 installer would upgrade it cleanly, and then booted it back up. For reasons related to my particular setup, the down time was more than 60 minutes. But that's not related to XCP-ng. The XCP-ng installer was maybe 10 of that. 20 of that was 3 reboots on a server that takes ages to boot. One thing that is a bit difficult is that the 8.3 installer doesn't notice ZFS volumes or help with ZFS. So after the upgrade, I have to follow a modified set of these instructions (modified because the package names have changed over time) to install ZFS and its components into the system. So the sequence is: Shutdown Install via ISO Reboot to single user mode Run yum update to pull in all the updates Run the ZFS commands to install ZFS on the host Reboot again Run normally Of course, I ended up rebooting more than just those 2 times, because I forgot that I would need to install ZFS (even though I did it on 2 different hosts already ) So now the pool is fully upgraded, everybody is happy. I'm now working on creating shared storage across the nodes. It's amateur hour over here. I appreciate all the help.

    Hi, "It depends" is the answer here Depends on: the number of concurrent users on your XO instance the size/frequency/number of backup jobs you have the number of hosts and VMs managed by XO Frankly, for a small setup (less than 4/5 hosts) with one users and few backup jobs, the default 2vCPU/2GiB RAM is enough. Especially since we improved various process to happen in a dedicated worker

    @lawrencesystems We added the healthcheck for full backup (here : https://github.com/vatesfr/xen-orchestra/pull/6401 ) Also we removed our js smb implementation ( https://github.com/vatesfr/xen-orchestra/commit/b50e95802c6a876d4e6ffd0c62c209a187b1bfb2 ) to try to circumvent the strange samba comportment fbeauchamp opened this pull request in vatesfr/xen-orchestra closed fix(backups): add healthcheck to full backup #6401 0 julien-f committed to vatesfr/xen-orchestra feat(fs): remove JS based SMB handler It's not well tested nor maintained.

    There's no black magic As @ronivay said, you need to tell the filesystem inside your VM that the disk grew. On Cloudinit-enabled VM, there's an auto-grow parameter that is checking at each boot if the disk was extended, and will automatically do it for you. But again, that's inside the VM. Keep in mind: it's not the job of the virtualization system to deal with what's inside the VM

    That would be nice if you open a support ticket with a support tunnel so we can take a look remotely

    @olivierlambert Thanks for that information, will use it next time I run into the issue. Before I read your above reply, I was poking around and noticed that the only SR I had added was disconnected, somehow. So I researched into it and discovered that this was my own doing. Without going into too much detail, I had converted my Active Directory environment from a Zentyal server to a Windows Server and I was hosting the SMB share on the old domain controller. So I had made a DNS error which was causing the SR to not be reachable from the XCP-ng host. So I deleted the SR and recreated it and viola I was able to create the VM. Honestly, I'm not sure how the two are connected since I'm not storing any disks on this SR; I only use it for ISOs which I mount into the newly created VM to install an OS and then I eject it. Long story short, my problem is solved but I'm still confused as to how it happened.

    @mjtbrady compression is used ( brotli, fastest mode by default) There is a problem on the size reported especially with encryption. I will add a task to the backlog to fix it (there is padding with encryption, that complexify the maths)

    Indeed, if your other hosts are somehow dead/unresponsive from XAPI perspective, ejecting them from the pool is an option to get your master booting those VMs

    @pdonias I am puzzled. What do you see? To be clear there are two problems. The selected directory truncates the directory name at around 46 characters ("/var/lib/docker/containers" in my original screen shot isn't truncated because it isn't that long). "Long" file/directory names in the "Select a file" drop down do not display correctly. Once a file has been selected, the "Selected files/folders" does show it in a scrollable "widget" that can then be used to see the full file name. My screen shots are from Chrome on Fedora. I normally use Fedora/Firefox which has the same issues. I set up the following as a test. Filename lengths are 10-80 characters long. root@debian42:~/testdir# pwd /root/testdir root@debian42:~/testdir# ls -l total 0 -rw-r--r-- 1 root root 0 Oct 7 09:50 1234567890 -rw-r--r-- 1 root root 0 Oct 7 09:50 12345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:50 123456789012345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:50 1234567890123456789012345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:50 12345678901234567890123456789012345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:51 123456789012345678901234567890123456789012345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:51 1234567890123456789012345678901234567890123456789012345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:51 12345678901234567890123456789012345678901234567890123456789012345678901234567890 Filename lengths 10-50 display.

    @olivierlambert i did update xoa again but no dice, i was wanting to export a couple VM's and do a head to head iscsi I/O test between vmware and xcp on identical hardware but not having much luck trying to get my VM's out of xcp. Guess I'll have to wait for this to work possibly.

    @daninmanchester Thanks so much - this is the exact same problem I had, which was further complicated by running XO in Docker running on the OMV host exporting the NFS shares. So basically you just built a small XO VM instead of running it in Docker? I had originally been thinking of making a small VM to run XO in a container there - just because Docker containers are super easy to keep updated and I could run some other orchestration-y stuff there too, like Rancher - but if you're saying that's a non-starter I'll just bite the bullet and build a tiny VM dedicated to XO and be very grateful to you for having saved me a lot of frustration.
