Debian Linux machine(s) losing SMB/CIFS connection to unraid share (cache yes) when transfering a file to it.
Hi,
a really strange problem...
I have a plenty of debian linux vm machines running on proxmox which are connected to several unraid user shares. They keep unexpected losing the connection to these shares. Not every share is involved at the same time, this means sometimes share1 is losing the connection and the other time share2 is involved. I can't tell when it happens... Yesterday every machine was connected to every share and today one machine loses connection to on sh
I think you are running into the stale file handle issue with CIFS mounts. What I think is happening is you are referring to a file on the cache and when it is moved the file handle has changed and you can then no longer access it.
When UD (Unassigned Devices Plugin) mounts a CIFS share, it uses the 'noserverino' parameter that prevents the stale file handle.
Example UD mount command:
/sbin/mount -t 'cifs' -o rw,noserverino,nounix,iocharset=utf8,file_mode=0777,dir_mod
