Description Rolf Linder 2006-08-05 11:38:44 EDT
Description of problem: An installation via nfs, where the server mounted a iso-file will freeze...(probably, always when its not a "normal" directory, for example a mount of dvd-drive or mount of an iso-file). Version-Release number of selected component (if applicable): Fedora Core 4: nfs-utils-1.0.7-13.FC4 Fedora Core 5: nfs-utils-1.0.8-2.fc5 How reproducible: always Steps to Reproduce: 1. mount a downloaded iso-file (probably, fc5-dvd iso) -> mount -o loop /path/to/iso /install 2. share the mounted iso via nfs -> in /etc/exports: /install *(ro,sync) 3. try nfs installation with a client Actual results: The installer (anaconda) will start working correctly, without any problems. then after copying the data it will freeze at the end (where normaly boot loader will be installed)...I tried this install from current (updated) FC4 and FC5 systemens with the same result...freeze on installation at the end. if you copy the content of the iso to a directory, then share this directory via nfs it will work. Expected results: complete installation, without freezing Additional info: -

Would it be possible to post a bzip2 binary tethereal network trace? Something like tethereal -w /tmp/data.pcap host <client> ; bzip2 /tmp/data.pcap

Created attachment 133861 [details] Out of network-trace, nfs read error (on FC4) this are the packages which are sent just bevore the freezing....
Comment 3 Rolf Linder 2006-08-09 13:56:44 EDT
So, after 4,5 hours of testing i get some additional information: the problem exist, when installing a newer FC version than the nfs-server. for example on my FC4 server i'm not able to cleanly install a FC5 (over mounted iso, nfs-shared). if you stay on the same version (installing FC5 from FC5 nfs server) the problem was not seen...also an installation of the new FC5.92 (FC6Test2) worked (via a FC5 server). so i guess this problem is related to FC4 and cause FC4 is out of official support (moved to fedoralegacy project) i guess this report will be closed. the solution to get solved this problem is update to (at least) FC5. sorry for this late conclusion...

I've had the excact same problem instaling FC7 from an FC5 nfs server, so it didn't go away with FC4.

I was just bitten by this bug when installing a new Fedora 8 system from a Fedora Core 5 NFS server. When I mounted the Fedora-8-x86_64-DVD.iso and exported the mount point via NFS, the installation would hang at seemingly random points (I tried it multiple times) with a "SQUASHFS error: sb_bread ..." After extracting the contents of the ISO onto a disk and exporting that directory via NFS, the NFS installation was able to proceed normally.

Have you also checked, that enough RAM is available. I also detected similar problems when the machine (server) does not have enough ram, since it operates all the time in the mounted ISO...probably you could provide once information about free memory (free).
