X-X-Sender: ohartman@mail.physik.uni-mainz.de To: freebsd-questions@freebsd.org Subject: NIS/YP -NFS -DISKLESS problem, weird Message-ID: <20021013132949.P14894-100000@mail.physik.uni-mainz.de> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Hello. I need some help again. As I posted yesterday herein, I migrate our NIS/YP and DHCP server from one system to another. This machine acts also as a limited NFS server for the diskless systems. So far. The strange and really weird problem is now, that althought I made a 1:1 copy of the diskless boot area from the old system to the new one and reconfigured isc-dhcpd to match the new IP, booting the client fails at a point I can not see why it gets stuck. The diskless root tree is exported read only, as done on the old system. I can see the X-Terminals and other diskless systems booting but when mounting / via NFS from the boot host, they get stuck. It seems that they can not mount the NFS file system, but that is not the problem. I exported then the root tree of the diskless systems to another system and I saw that they can mount it without any problem. But now the weird thing comes into play: I can travers via cd and ls __all__ directories and can list all dir entries execept those of etc!!!!! I deleted /diskless/etc, /diskless/conf/base/etc and created them via mtree -deU -f /usr/src/etc/mtree/BSD.root.dist -p /diskless and populated them with some self made files via touc etc. No problem, I can ls the entries and show them. But whenever I trie to copy the base population from /usr/share/examples/etc/* or /usr/src/etc/* into the base etc directory, each following ls freezes the terminal and results in a stuck/stale NFS file handle (I guess, I do not get any errors, the terminla is simply locked up). When I delete all the entries in the mentioned etc dirs on the fileserver (the boot server for the terminals) I do not have trouble anymore, but when populating it again the result is the same. What's going on there? All systems we use are FreeBSD 4.7-RELEASE and the machine which acts as boot server for diskless clients has been set up newly this week. So, this seems to me to be a harsh bug. It does not occur on the old boot server. Can anyone help, give a tip or hint? What's wrong here? -- MfG O.
