Suspend on ram fails when using luks on lvm #51

Closed PhotonQuantum closed 3 years ago

PhotonQuantum commented 5 years ago

We've already known that ext4 barrier prevents system from suspending, so remounting cryptdevice with nobarrier option will solve the problem.

But src/ykfde-suspend#L79 can't handle ext4 filesystems on lvm layers as is described at ArchWiki now, hanging the suspend process.

I believe that the problem can be solved by detecting ext4 filesystems running on crypted lvms and remount them accordingly, or adding a config option to allow users specify their own ext4 logic partitions.

However, I haven't figured out yet whether these approaches are feasible and how they can be implemented. Any ideas?

I think we should probably expose a knob for this. cc @Vincent43
