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 ?
Stephan, was 4.14.101 your last "good" kernel? We also have 4.14.103 and yesterday 4.14.106 was released.
