Try changing your fstab entry to
Code: Select all
//PC/Share /mnt/share cifs _netdev,username=username,password=password 0 0
That should delay the mout until after the network is up.
You should also consider using the "noauto" and "x-systemd.automount" options. With those the share won't be mounted during boot (or on mount -a) but on first attempt to access it.
Oh, and expect permissions issues if you want to write to the share. Default permissions only allow writing by the owner who, unless specified in the mount options will be root when mounting via fstab.
