i think is better to wait for 6.12... is a main 6.11 kernel issues (check other distro problems with idrac and kernel 6.11), i think the proble come because (on my r420 server) the video memory is shared with idrac.Reporting a new issue with 6.11.11-1 - Proxmox is not reliable on this version as a glusterfs client. Intermittently, records are not written and files are not transferred via rsync between the client and the server. No errors logged on either the client or the server, so this is a "silent failure". Reverting the client Proxmox server back to 6.8.12-7 eliminates the problem.
