(2) is unexpected by me. are you indicating that the file is not visible at the nfs client or when logged into the server? On the server is a big problem. At the client is probably some minor misconfiguration of the services on the server. > 3) upon failback, I get a stale NFS handle error - in my haresources file, I > have the following entry: what does `ls -ld /var/lib/nfs` (pn both machines) return? The reason I ask is that the data in /var/lib/nfs needs to be on a disk shared between the machines and needs to be accessible _before_ starting nfs and nfslock services. > > fedora1 IPaddr::172.30.30.200/24/eth0 drbddisk::r1 > Filesystem::/dev/drbd1::/data::ext3 restart-nfs restart-rpcidmapd > do you control any other related services with ha? like the nfs service? > -- > > Any idea if my config is wrong or is there an issue dealing w/ large files > either in drbd or the ha or NFS itself? Thx in advance. not enough info, but I know I have worked with files bigger than 2GB and had no problems on drbd 0.6.13 on Fedora Core 1 over NFS managed by Heartbeat. -- Todd Denniston Crane Division, Naval Surface Warfare Center (NSWC Crane) Harnessing the Power of Technology for the Warfighter __ please use the "List-Reply" function of your email client.
