Locking issues on Clustering File Systems
*Excerpt
open discussion on locking issue on clustering file systems, especially associated with fs/dlm code
Description
User space clustering stack brings advanced and flexible cluster file systems (e.g. OCFS2), which involved in the usage of unified Distributed Lock Manager code in Linux Kernel (a.k.a fs/dlm).
This talk intends to invoke the open discussion on (but not limited to) DLM and clustering file system realted issues. For examples, the lock mastering expense, lock communication cost, dlm compatible issue between fs/dlm and OCFS2, deadlocking detection …
