RE: XCP-ng 8.2.0 beta now available!
I upgraded to 8.2.0-beta to fix this issue nfs-storage-latency. Bellow are some tests done, if you need any specific tests just let me know.
I’m running XO from sources xo-server 5.67.0 xo-web 5.71.0
XEN-HOST-01 Dell R720
XEN-HOST-02 Dell R710
TrueNAS NFS Storage over 10GbE
I upgraded from 8.1.0 patched to 8.2.0-beta via ISO install. Install went through with no troubles. The host booted with no problems. All networks and storage was present.
All VMs booted and came back up with no issues and guest tools running. VMs consist of CentOS 7 & 8, Debian 9 & 10, Windows 10Pro
Successfully live migrated VMs from 8.1.0 host to 8.2.0-beta with no issues.
Attempted VM migration from 8.2.0-beta to 8.1.0 host failed as expected.
Successfully migrated VMs between 8.2.0-beta hosts.
Could not change pool master from 8.2.0-beta to 8.1.0 host. Get Unknown error from peer.
Successfully changed pool master with both hosts on 8.2.0-beta.
Both host on 8.2.0-beta, shut down host-02 which was not the pool master and the shared storage shows partially connected and no stats available for storage. Reboot host-02 and shared storage is now healthy and stats are back. Disabled host-02 and shutdown and still had the same issue as above. The only was to get stats back and get shares storage back to healthy and stats working is to forget the storage attached to host-02 that was shut down.
XCP-ng Center v20.04.00.32 will not connect to 8.2.0-beta hosts.
Had to reinstall xscontainer package to have docker container visibility in XO.
