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.
well ... saw that this morning, but I'm not sure we were doing these operations in the past.
I can try the 106 this afternoon. I'll keep you posted.
I'd try a different kernel... and also a different SD card. I've seen a fair share of oddities that boiled down to being SD card issues.
