Khm, in one of our project X-terminals use swap on NFS with Peter's patch. But in tests loop on file on NFS without VM patch was very stable. X-terminal has 16MB memory. And yes, I use swap on Lustre as tmpfs. mount -t tmpfs -o size=64G tmpfs /tmp -- Serge Ryabchun <[EMAIL PROTECTED]> _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
