Package: linux Severity: normal Dear Maintainer,
I am in a situation where I am using a GFS2 cluster in virtual machines and realized I couldn't do it with the 'cloud' kernel because the 'dlm' kernel module is not present in this flavour. It does work when I switch to the bare-metal kernel. Other distributed fs might require 'dlm' (OCFS2 comes to mind). It's a handy tool when you can mount the same NAS-like (Ceph, etc) on multiple virtual machines and avoid SPOFy NFS configurations this way. The diff between the bare-metal and cloud configs seem to be : CONFIG_DLM=m CONFIG_DLM_DEBUG=y CONFIG_GFS2_FS_LOCKING_DLM=y On an AMD64 Bullseye system, the /lib/modules part of the cloud kernel weights 72584 kB and adding the dlm.ko modules seems it would add 480 kB which is not negligible (+0.7%). -- System Information: Debian Release: 11.6 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.0.0-0.deb11.2-amd64 (SMP w/4 CPU threads; PREEMPT) Kernel taint flags: TAINT_UNSIGNED_MODULE Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled
