    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.

    File Restore Fails

    @NeilGrevitt Whilst migrating my other backups to NFS, I noticed that one of the VM backups is able to perform file restores successfully. The successful VM is Ubuntu 22.04.1 LTS, but has been upgraded multiple times and was originally a flavour of 18.x LTS somewhere along it's life. The unsuccessful VM is Ubuntu 20.04.5 LTS that I believe was installed at this version. The only difference I can see is the output of lvscan, which does point to an issue with LVM! Successful VM: :~$ sudo lvscan :~$ Unsuccesful VM: :~$ sudo lvscan ACTIVE '/dev/ubuntu-vg/ubuntu-lv' [<19.00 GiB] inherit Not sure where to go now but thought it worth reporting!

    @mauzilla Just an FYI, I have not tested the latest Scale 22.12 RC1 for performance but the previous versions of scale under some conditions was quite a bit slower. I have a video covering this topic here with the benchmarks and methodology used for testing. https://youtu.be/BoiHHnBDg0E

    Thanks all for your comments. I've managed to overcome the NFS errors listed, by using the new "multiple data blocks" setting! So for me, looks like backing up to .vhd won't work on either SMB or NFS.

    You can "reset" delta on an CR on two methods ( I use the firs one ) : Set number of full backup interval, under Advanced settings (left down). And can be predicted as fallow Reset = full backup interval / number of delta per day. So for 4 deltas per day Reset = 21/4 = 5 rest 1, reset will be on day 6 on first backup. [image: 1668752674017-e6f37d80-9c7d-4d16-bdea-903612fc251e-image.png] [image: 1668752712035-9eb6c381-a130-4d27-9e10-cd441338c666-image.png] Or on schedule on Replication retention [image: 1668753256557-6ac7be5a-b462-4e57-89cf-f58f20e4a4b4-image.png] Force full backup is to force full backup on next run

    @Momi_V Thanks for providing details. New documented setups are helpful to others. I'm using this installer script on a Debian 11. (Thanks to @ronivay!). Not exactly a quick hands off deployment but it works well for me.

    Indeed, that's not "usual" if you comes from a purely Linux/KVM world, where the host is the entire machine.

    @MichaelCropper That's awesome! I'm glad the usual computer pixie dust fairies dropped by and fixed the issue for you. Poor Windows though... you initially laid the blame at their feet, but it seems more like this was a Google Chrome issue. I've noted a LOT of peculiarities with Google Chrome as of late and have started to migrate away for that reason. Reading a lot of forums on Reddit and other IT sources, this seems to be something that is pretty wide-spread. In any case, it's working for you now... until Google changes something again. LOL I hope you have a great weekend!

    Hi, I think it's used for file level restore on S3 enabled backup. It's not crucial as long as you don't need to restore individual files on S3, obviously. @julien-f is there a way to avoid this dep manually in order to build the rest of XO?

    Hi @BenjiReis, the certificate procedure I posted yesterday isn't quite right and although the plugin will enable, TLS will not negotiate. My openssl.conf defaults to adding x509v3 attributes that breaks the TLS negotiation process. Here's the correct procedure on Rocky Linux 9. Should work for most other recent Linux flavors. Create a temporary directory to work in, and copy your OS's openssl.cnf file into it. Edit the [ v3_ca ] section so it only has the following 2 entries: subjectKeyIdentifier=hash authorityKeyIdentifier=keyid:always,issuer Now create the CA (run all commands in your tmp directory). I am also now using 4096 bit strength: openssl genrsa 4096 > ca-key.pem openssl req -new -x509 -config ./openssl.cnf -nodes -days 365000 -key ca-key.pem -out ca-cert.pem ** The server certificate step in the previous post is not necessary so just skip it. Now create a file called client_attr.cnf and put the following entries in it: subjectKeyIdentifier=hash authorityKeyIdentifier=keyid,issuer Now Create the client certificate: openssl req -newkey rsa:4096 -nodes -keyout client-key.pem -out client-req.pem openssl x509 -req -days 365000 -set_serial 01 -in client-req.pem -out client-cert.pem -CA ca-cert.pem -CAkey ca-key.pem -extfile ./client_attr.cnf The ca-cert.pem and client_cert.pem should now conform to the correct x509 format that will work with XOA and hence cross-server private networking. Sorry for the incorrect procedure, it was a late night Cheers.
