Mounting and fstab

Cheat sheet

• lsblk -f devices and filesystems
• findmnt the mount tree
• blkid /dev/sdX1 UUID for fstab
• sudo mount -a apply fstab without a reboot (a check!)
• sudo mount -o remount,rw / remount root rw (recovery)
• sudo mount --bind /srv/data /var/www/data a bind mount
• fuser -vm /mnt who's holding the filesystem (for umount)
