Same here: [root@host-115 ~]# grep polld /etc/lvm/lvm.conf # metadata, cache, locking, lvmpolld. Use "all" to see everything. debug_classes = [ "memory", "devices", "activation", "allocation", "lvmetad", "metadata", "cache", "locking", "lvmpolld" ] # Configuration option global/use_lvmpolld. # Use lvmpolld to supervise long running LVM commands. # from the original LVM command to the lvmpolld daemon. This allows # After lvmpolld takes over, the LVM command displays the progress # of the ongoing operation. lvmpolld itself runs LVM commands to # manage the progress of ongoing operations. lvmpolld can be used as use_lvmpolld = 0 Created attachment 1119086 [details]
Patch to mark config settings related to lvmlockd and lvmpolld as unsupported
We need to add an extra patch for 6.8 to mark all these configuration settings as "unsupported".
Should these references be removed as well? [root@host-123 ~]# vgcreate --shared vg4 /dev/sdd1 Using a shared lock type requires lvmlockd. Run `vgcreate --help' for more information. VGCREATE(8) VGCREATE(8) --shared Create a shared VG using lvmlockd. lvmlockd will select lock type sanlock or dlm depending on which lock manager is running. This allows multiple hosts to share a VG on shared devices. See lvmlockd(8). OK, I'll go through that once again... The upstream should be fixed here: either excluded from the build or else marked as only applicable when available on the system. RHEL-specific patches should be avoidable. OK, so systematic solution here is for every conditional setting that is based on the result of configure script will be placed into the generated lvm.conf only if the feature was configured via configure. Also, there's going to be a flag marking such config options in config_setting.h file (also based on the result of configure script) and if someone uses an lvm.conf option that is ignored (because support for that feature is not compiled in), there's going to be a warning message issued that the configuration option has no effect. Of course, there are more settings here, not just lvmlockd and lvmpolld - any setting where the functionality is based on the result of configure script - so it's conditional. Let's go with marking these lockd/polld features as available in man pages/config only if LVM is compiled with lockd/polld. Patch: https://git.fedorahosted.org/cgit/lvm2.git/commit/?id=06ef7ba8765d64044b008a33f1c1faeac6112a4a I'll open a new BZ for global solution as mentioned in comment #7.
