hope I can get some help. I have to be honest up-front, I do not have great linux skills - still learning.I recently upgraded to 20.04.1. I don't know if these errors started right after that, or after something else I had done.
kernel: [258605.922058] CIFS: VFS: \\192.168.2.107 Send error in SessSetup = -11
I've tried searching for what -11 means, but I can't seem to find what this error is indicating. I know these errors weren't there prior to 20.04.1 LTS upgrade.
This is the statements for my fstab mounts: I've been tweaking them quite a bit last few days trying to resolve the error...
//192.168.2.107/Multimedia/New /home/New/ cifs credentials=/etc/.kreditiv3,_netdev,vers=2.0,nobrl,iocharset=utf8 0 0//192.168.2.107/Multimedia/Parents /home/Multimedia/Parents/ cifs credentials=/etc/.kreditiv3,_netdev,vers=2.0,nobrl,iocharset=utf8 0 0//192.168.2.94/video/Movies /home/movies/Movies cifs credentials=/etc/.kreditiv1,_netdev,vers=2.0,nobrl,iocharset=utf8 0 0//192.168.2.107/calibre/ /home/calibre-library cifs nobrl,credentials=/etc/.kreditiv3,uid=rob,gid=family,_netdev,vers=2.0,nobrl,iocharset=utf8,sec=ntlmssp 0 0//192.168.2.27/movies /home/movies/oldies cifs users,credentials=/etc/.kreditiv2,uid=root,gid=root,_netdev,vers=1.0,nobrl,iocharset=utf8 0 0//192.168.2.94/NetBackup /home/backup cifs credentials=/etc/.kreditiv1,_netdev,vers=2.0,nobrl,iocharset=utf8 0 0//192.168.2.94/Audiobooks /home/audiobooks cifs credentials=/etc/.kreditiv1,_netdev,vers=2.0,nobrl,iocharset=utf8 0 0Everything seems to actually work, except for the fact I'm getting lots of errors. It seems to give the error a couple of times every hour, but I don't know why, or which mount. Without disabling a mount for a few hours, and breaking my applications (sonarr/radarr/plex/calibre), is there something I can check?The mounts are physically on external raid boxes (qnap and synology devices).
