Hi everyone! I've already asked this question (basically) in the questions list, but I didn't get anything that really helped me along. I am hoping to get a little further on this list. Using my search engines, I have found out that exporting a ZFS is a by picky. However I have found no general rules of what to do - yet. My file server is called obelix, my workstation falbala. Feel free to make fun of that fact. :-) obelix boots from an SSD. There is a raidz2 configured with 7 HDDs, mounted under /zfs/arc1. This is the main (basic, root) mount point of the ZFS pool and it is pretty much empty. There are other tanks I have defined and they are under /usr/archive/. The directory /usr/archive/ is of course still part of the SSD. When I set /usr/archive as an export in /etc/exports, I can mount that from falabala. I see all the subdirectories too - each of these are ZFS tanks. However, I cannot access the contents of the tanks. I've played around here a bit and there are two things that can happen: 1. I can dive into the directories but they look empty from falbala. 2. Access to the directories is refused completely. I don't remember what I did to get each of these results, so please don't ask. :-) Ok, so I read that I cannot export all ZFS mounts together like this and have to create an export for each seperately. Fine with me. :-) So I created and export to /usr/archive/shared which is the mount point of a ZFS tank. But if I try to mount that via NFS from falbala, the connection is denied completely. This is logged in /var/log/messages on obelix - without any reason however. Now it might be that I am just to dumb to understand the works of NFS and ZFS or I am just missing a piece of the puzzle. Can someone please give me a push, please? Regards, Chris
