Sorry, I don't know. Maybe this is a good place to start: http://nfs.sourceforge.net/nfs-howto/ar01s02.html#help_and_info
, suggesting that the kernel based nfs server is faulty and that the issue vanishes when using a user space nfs server. In order to test this I removed the kernel based nfs server from the machine and installed nfs-server-2.2beta51-225.2. The system now allowed me to write to the nfs-share and the files did not get
Thank you Dave for the pointer. Indeed searching the archives of this list did reveal some important information. This post http://marc.info/?l=linux-nfs&m=113090817418144&w=4 describes that a similar problem with nfs actually turned out to be due a size limit of the filesystem and not related to nfs at all. Reading this I went ahead and checked the block size of my ext3 partition: 4K. In fact the maximum ext3 filesystem size with 4K blocks is 8TB, while I am running it at 15TB. Pretty scary, considering that we don't want to loose the data we already have there. Remains the question why neither the yast-lvm module nor resize2fs complained when I gave the instruction to grow the filesystem to an unsupported size?! The following is just to document some extra information I acquired: Before I knew about the fs size limitation I also found this post <http://lkml.org/lkml/2006/2/21/131 truncated to 0B. For a second it seemed that the problem was solved. However: A "df -h" on the nfs client showed: exppraid.expp.ist.utl.pt:/export/ raid 783G 719G -89.5G 114% /private/var/automount/exppraid More space used that available - would be nice if it only where true. When copying file to the nfs share on the client I would sometimes get: "nfs server exppraid.expp.ist.utl.pt:/export/raid: lockd not responding". So eventually I figured that user space nfs server was not the solution to my problem.
