Hi list, I am going to build an active active NFS server, where one exports a public directory, and the other the home directories. In case one fails, both should be exported by the remaining one server. I have a shared storage on a SAN, connected to both servers, I use the Filesystem ocf script to mount/umount the partitions (ext3, ocfs2 doesn't have ACL's, and I do not get GFS2 to work). Therefore I cannot run a nfs server clone, because I cannot umount the partition when the nfs server still lives on it, and the shared IP is wandering. I only see the LSB Script available for managing the nfsserver, but with the LSB script, only one NFS server can be started or stopped.
So I have to configure two NFS resources using the LSB script, so that both can life on different servers. But now when I manually tell on nfs resource to move to another server, then both nfs resources will not be available for a short time. I also saw some problems when a dead node comes back into the cluster, also both nfs server resouces were not available for a short time. An other option would be to create a OCF script (I haven't found one) to manage the nfsserver. In the manual page of rpc.mountd I have seen that it is possible to specify a exports file and the port automatically. But I don't know what kind of other problems I might get, or whether it will be possible to run two nfsservers in parallel. anybody has an idea? kind regards Sebastian _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
