From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows 98) Description of problem: I can share /home and numerous other partitions and directories using Linuxconf. I do an exportfs -r and then an exportfs and the shared directories all show up. We have numerous Solaris machines, some with Solaris 2.6, one with Solaris 7, and numerous with Solaris 8. The 2.6 and 7 machines can mount every directory being shared out by the Linux server (even the /home). The Solaris 8 machines can mount all the shared directories except for one, /home. When they attempt to mount it they receive a "Permission denied" error. The command I am using to mount the Linux's /home directory on the solaris machines is as follows: "mount -F nfs jcatslx0:/home /mnt" Why is it I can mount all the other shared directories except /home? and why can the Solaris 2.6 and 7 machines do it. Sounds like a conflict with the current version of nfs-utils (I have 0.3.1-5 loaded) and the Solaris 8 nfs client component. I have noticed that if I uninstall the nfs-utils rpm in the GnomeRPM utility and then reinstall it, the Solaris 8 machines can then mount the /home partition, but as soon as I reboot them they lose the ability and get the "permission denied" error. I also went to the rawhide ftp area and downloaded nfs- utils 0.3.1-11, but it didn't resolve the problem. Any help would be appreciated. Thanks Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.See Description above 2. 3. Additional info:
Recently figured out that in order to receive the "Permission Denied" error upon mounting the linus server's /home directory, you must have a sub-directory of /home already mounted. In our case we have the directory /home/jdata30/data_30 mount up at boot time (in the Solaris 8 machines' /etc/vfstab file). So just prior to tryinf to mount the linux machine's /home directory you can do a "df -k" and see the linux machine's /home/jdata30/data_30 directory already mounted on a mount point (in our case the mount point for /home/jdata30/data_30 is /home/jdata30/data_30). I now believe the Solaris 2.6 machines would also get the persmission denied error if they had the /home/jdata30/data_30 directory mounted ahead of time as well (they don't mount any directories from the linux server at boot time). After I figured out that having a /home sub-directory mounted prior to attempting to mount /home was causing the problem, I figured out a way of getting around this problem. What I do now if I need to mount the linux server's top level /home directory on one of the Solaris 8 machines: 1. "umount" the /home/jdata30/data_30 directory on the Solaris 8 machine (as root of course). 2. go over to the linux 7.1 server and do a "exportfs -r" as root. 3. go back to the Solaris machine and now mount the linux machine's /home directory ("mount -F nfs jcatslx0:/home /mnt"). This time it will work. 4. mount the /home/jdata30/data_30 At this point both the linux machine's /home and /home/jdata30/data_30 directory structures are mounted (separate mount points) and are both accessiable. Once I'm finished using the /home directory, I can then umount both the /home and /home/jdata30/data_30 directories, do a "exportfs -r" on the linux server again, and finally remount the /home/jdata30/data_30 directory. Found that if you don't unmount the /home/jdata30/data_30 prior to the exportfs -r command, it will show up as a stale FS when doing a "df -k" on the solaris machine. Is the nfs-utils (nfs server) portion on the linux machine working properly, or is this something that needs to be fixed by you guys? I have this work-around, but I'm not exactly thrilled about it. Let me know if this is how the Linux server should be handling it, or if there is a bug in the nfs-utils. Thanks Don Penta
This is actually correct behaviour by the NFS Server. In general, NFS servers do not allow hierarchical exports. The one exception to this is if the exported directories do not themselves lie on the same file system.
