Dear DRBD/LINSTOR users on PVE, this is the RC1 of the upcoming 6.0.0 release. There are no dramatic changes, but by bumping the major version I took the chance to flip some defaults and remove some very old cruft.
The option 'preferlocal' is now set to 'yes' by default. This means when you create a VM, the plugin tries to create storage on the node the 'create' command was issued. Previously it could have been that you selected nodeA in the GUI, created the VM and it ended diskless on nodeA and with actual storage on nodeB. Keeping a status cache ('statuscache') for storage pool information is now enabled by default and the default duration is 1 Minute. This was available for a long time and users with huge clusters ran into issues. Unfortunately PVE queries information a lot and the internal PVE cache that can be used does not solve all issues. The 'controllervm' (not to confuse with 'controller') setting that was used for some form of controller HA is gone. We nowadays have ways better means to implement a HA linstor controller[1]. The 'redundancy' setting code was removed. This was completely dead code, and was replaced with LINSTOR resource groups and their redundancy setting a long time ago. If you have the latest version installed it should be sufficient to replace the LINSTORPlugin.pm on your system (/usr/share/perl5/PVE/Storage/Custom) and restart the pvedaemon.service Please test! If nobody complains this will become 6.0.0 in about a week and get moved to the repositories.
