    upgrading Alma/Rocky/RHEL LXC container

    In essence neither RHEL, nor Rocky recommend (or suggest/support) upgrading in this way, so if Alma follows the same scheme then yeah. Unsupported, but if it works .. it counts ;)

    [TUTORIAL] PVE 7.x Cluster Setup of shared LVM/LV with MSA2040 SAS [partial howto]

    i have not changed my setup since the beginning of the/this post. So the answer is : No The reason i used GFS2 in combo with LVM is that i actually offer a filesystem to ProxMox.
