Filesystem for a shared block device for a linux
Is there such a thing? I don't care about performance, I just need to be able to have access to the same block device from two computers. The block device does not have anything fancy (like reservations), so it's pure read/write device without caching or other nasty tricks.
They are named cluster filesystem https://en.m.wikipedia.org/wiki/Clustered_file_system . There are different products with different features. For instance: GFS2, OCFS2, Lustre
