Hi, We are using the aufs module (20080331) to deal with a multi diskless nodes system through NFS. The linux kernel is the 2.6.18 from RHEL 5 (not really the vanilla one). For each nodes, we have a specific rw branch plus two others common ro branches which are aufs mounted and nfs exported as root filesystem. We have from 5 to 10 diskless nodes per NFS servers. And this is working quite well.
Nevertheless, we are experimenting some transient instability. Time to time, at boot time, one client is not allowed to mount its rootfs (permission denied) and the server is rejecting the request because the mount point is not seen as exported by nfsd even if the exportfs was previously done and confirmed by exportfs -v command. I'm trying to workaround the documented warning regarding find_exported_dentry exporting once one of the ext3 branches but we still have this warning. I'm not sure it may be the root cause of this issue but I would like to get rid of this warning before going deeper into my investigation. Any other idea may be really helpful. -- Régis ODEYE Kontron Modular Computers SA 150, rue M.
