I have a Raspberry Pi running Ubuntu Mate 16.04. Until today, I had a thumb drive with a single partition connection connected to it and the folder
lost+found was hidden when viewing the folder on my laptop (running Ubuntu 16.04) in Nautilus just like
/lost+found on my laptop's system is hidden in Nautilus.
Today connected a HDD and created a raid 1. The raid is mounted in
/media/raid. The HDD has access storage space which has its own partition which is mounted in
/media/non-raid. Both mount points are connected to newly created partitions and both exhibit the strange behavior of
/media/non-raid/lost+found) not being shown when I navigate to their parent directory in Nautilus on the Raspberry Pi but being shown (which they shouldn't) when I connect to my Raspi from my laptop in Nautilus via SFTP and navigate there.
The tick in
View → Show Hidden Files of course isn't set and no other hidden files are shown. I restarted both machines.
I changed the permissions on the file systems to fit my needs.
/media/non-raid doesn't hold any data yet, so I'm posting the output of
ll executed at that location but the rights of
/media/raid are the same.
christoph@christoph-pi:/media/non-raid$ ll total 24 drwx------ 3 christoph christoph 4096 Oct 11 16:15 ./ drwxr-xr-x 5 root root 4096 Oct 11 17:09 ../ drwx------ 2 root root 16384 Oct 11 16:15 lost+found/
christoph, of course, is my username. I connect via SFTP using the same account.
What causes this strange behavior of Nautilus and how can I make
lost+found hidden, again?
