Hi Paul, Locking is part of the core GlusterFS protocol but the NFS server module does not have NLM support yet(NLM is the locking protocol associated with NFSv3). On linux, the workaround is generally to mount with the -o nolock option although I dont see why excluding this option results in stale file handle and other errors. let me go through the complete thread, I'll reply elsewhere. Today, if locking among multiple client machines is a must-have, you'll have to use FUSE. paul simpson wrote: > so, while your all about - my big question is can/does gluster (with > NFS/fuse client) properly lock files? > > ie, a simple test is to checkout a svn tree to a gluster, modify, checkin, > list, alter, revert. everytime i do this with 3.1.2 i get input/output > errors from my client machine within a few minutes. > > > > ------------------------------------------------------------------------ > > _______________________________________________ > Gluster-users mailing list > Gluster-users at gluster.org > http://gluster.org/cgi-bin/mailman/listinfo/gluster-users
