Hi there. Strange issue with NFSv4 this morning. RPI3b+ with kernel 103 and fresh yum update, set up as NFSv4 client. Trying to copy a whole folder with a few GB (many .rpm & .tgz and a few .img), from NFS mounted source to local filesystem. (cd /shared.nfs ; tar c) | (cd /local ; tar x) After a while ... - PING to the RPI works. - SSH sessions got frozen and login is impossible, even with USB keyboard on the RPI. - Sometimes, I do see some kernel backtrace on the VGA, but not always. As I have to switch off the RPI, there is nothing left in /var/log/message when system is back. If I do this copy with full SSH, the copy works perfectly well. (ssh xxx "cd /xxx ; tar c") | (cd /local ; tar x) I have the feeling that the system hangs often on the same huge file, but when I do copy it manually, even in a loop ... nothin happens. Any idea ?
