The situation: Server with Gentoo Linux and Samba on it. There's around 15 Windows PCs, one MacBook Pro and one Samsung's laptop with Ubuntu. There's no domain, just a workgroup and the server is used only for Samba shares. On Ubuntu I use gvfs to mount samba shares.
And the problem: One day around half of directories went missing, but only when viewing on this Ubuntu laptop. If I ssh to the server I can see the missing files/dirs and I can also see the missing things from win or mac computers.
The tempfix: When I rename some of the missing directories, even if it's one symbol, missing directories reappear … even without reloading/refreshing the gvfs-mounted share. If I rename instantly back to the previous directories/file names, all previously missing dirs/files instantly go missing again.
So, as this problem reappeared again around month later, I could use some advice where to start checking.
