Err probably not, but I don't see much activity on the server, ie I can still access it not like when I do a local mkfs. I just tried with 10 journals and the machine hung for getting on for 30 seconds before I killed it. I didn't want to wait any longer as I have an OGSF filesystem mounted and I didn't want it to time out and get stomithed.

On the subject of locking; am I correct in thinking that when a node gets a lock, it holds on to the lock until someone else tells it to release it? > > -- Ben -- > > Opinions are mine, not Intel's > > > ------------------------------------------------------- > Enterprise Linux Forum Conference & Expo, June 4-6, 2003, Santa Clara > The only event dedicated to issues related to Linux enterprise solutions > www.enterpriselinuxforum.com > > _______________________________________________ > Opengfs-devel mailing list > Opengfs-devel@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/opengfs-devel ------------------------------------------------------- Enterprise Linux Forum Conference & Expo, June 4-6, 2003, Santa Clara The only event dedicated to issues related to Linux enterprise solutions www.enterpriselinuxforum.com _______________________________________________ Opengfs-devel mailing list Opengfs-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/opengfs-devel
