Hello. I need to state right away that I am not an IT person and only
began learning Linux so I could create a small home music-and-backup server.
The little server in question is a Wandboard running Arch Linux ARM. It
comprises two HDDS which mirror each other. it serves a Windows PC and a
Logitech Squeezebox music appliance. It has no HIDs and I administrate
it from the Windows (Ultimate 7) PC using PuTTY.
The shares on the Wandboard have no problem being read from and written
to by the Windows PC and the Squeezebox. But shares on the Windows PC
mounted on the Wandbord at boot become inaccessible after a certain
period of time (sometimes as short as 20 minutes). An ls command to list
the mount directory of the share shows "Host is down. " Chmod shows the
mount directory (/mnt/Work) with ??? ??? ??. An attempt to remount
after unmounting shows "No such file or directory." Network traces show
no SMB2 calls being mde to the Windows PC.
Setting up the Windows share to automount with systemd and auto-unmount
after 1 minute without activity has helped in that the share remains
accessible (so far for up to 12 hours and counting). *But if* I cd into
the actual mount directory (which seems to cause the auto-unmount to
stop functioning), the same symptoms appear. There is only one slight
difference: Instead of "Host is down" the error is "cannot access
'/mnt/Work': No such device."
I have been to several different forums (including Arch Linux Questions
and Server Fault, etc.) with this question and no one has been able to
or found the time to help. I can't find a specific cifs forum. I am in
the process of reading the LinuxCIFS utils documentation, but it is slow
going for me. I would appreciate any tips anyone can give and/or the
name of an appropriate forum or mailing list. I can supply any
information, but may need help with gathering it.
Thanks for reading.
