More findings. Reminder, with the original report I found: - files for no reason changing ownership and group to root/<owngroupname> - data corruption as in inserting binary junk obviously from ports - data corruption as in malformed ascii text that might be a bug I have in my code that is only exposed in FreeBSD
I ran the script on a Linux machine in the same situation again the same NFS server, it worked fine. I haven't look at blocksizes, NFS versions etc in play yet. I ran with oldnfs (reboot), which showed only the third problem. I re-ran with newfs (reboot) which worked (all three problems absent). I then started building ports/land/gcc47 at the same time as I re-started my crazy script and it too only a few seconds for an unexpected ownership to root to occur. My next steps are: - trying block sizes and other parameters, maybe use a different NFS version with the Linux client. My NFS server is newly upgraded to Linux kernel 3.1.5 - running my script on a FreeBSD host with local disk to see whether problem #3 is a general problem that appears or is exposed only on FreeBSD - capture tcpdump as mentioned earlier I will probably have to turn debug off since this script run is dominated by system time now and gets 10x slower as it is now.
