chrisf Posted March 2, 2017 Share Posted March 2, 2017 Today I had problems copying files from my Synology NAS. Browsing the directories was fine but copying files resulted in I/O error. No errors in any logs (dmesg, /var/log/messages) The kernel is not built with rpc debugging available so I couldn't look further in to the cause. Armbian 5.26 didn't work Armbian 5.25 didn't work I Downgraded all the way back to 5.23 (kernel 4.8.4) and everything works perfectly. Link to comment Share on other sites More sharing options...
chrisf Posted July 10, 2017 Author Share Posted July 10, 2017 I upgraded from 5.23 to 5.32 and it still doesn't work. I get Input/Output errors root@cubie:~# mv /mnt/data/file . mv: cannot open ‘/mnt/data/file’ for reading: Input/output error /mnt/data is an NFS share from a Synology NAS. I don't have these problems on any other machine except Armbian with a recent mainline kernel I've downgraded to 5.23 and it's working again.

chrisf Posted July 22, 2017 Author Share Posted July 22, 2017 That was the extent of the logs. There's nothing in syslog or /var/log/messages It's NFSv4 I've had no end of trouble tonight too... not sure hat triggered it. Been getting the same Error 5 sometimes and a File Locked error too The server is a Synology DS215j I've just switched the mounts to NFSv3 and it seems to be working again Link to comment Share on other sites More sharing options...
