I have three drives mounted in my Ubuntu Server 14.04. These are external USB drives that I use for backup, file sharing, and media storage:
/dev/sda1 on /mnt/fileshare type ext2 (rw,noexec,nosuid,nodev)
/dev/sda2 on /mnt/media type ext2 (rw,noexec,nosuid,nodev)
/dev/sdb1 on /mnt/backup type ext2 (rw,noexec,nosuid,nodev)
I recently had some issues with the way these drives were being mounted and had to unmount and reboot my server many times. At some point, once I got them mounted properly, I noticed that a "lost+found" folder had been created inside each mounted folder i.e. /mnt/fileshare/lost+found, even though there are actually no files in /mnt/fileshare.
Can someone please tell me:
1-What purpose do these folders serve?
2-What can I do to remove them? (or do I absolutely need to leave them there?)
Thanks for the help.
