External Hard Drive Info

This table keeps track of the Raspberry Pi's external storage setup.

Device Filesystem Label Mount Point Mount Options
/dev/sda2 ext4 storage /mnt/storage defaults,relatime,commit=600
Device UUID
/dev/sda2 5bb54030-2df7-4798-afb5-bd2878ae0def

Hard Drive commands

purpose command
find the UUID lsblk -f
verify mount point df -h : grep storage
check filesystem typ sudo blkid / dev/sda2
remount drive without rebooting sudo mount -o remount /mnt/storage
check if new optinos are applied mount : grep storage
verify changes cat /etc/fstab : grep storage

mount options available

Option Description
defaults Uses the default options: `rw, suid, dev, exec, auto, nouser, async`.
rw Mounts the filesystem as read/write (default).
ro Mounts the filesystem as read-only.
noexec Prevents execution of binaries on the mounted filesystem.
exec Allows execution of binaries (default).
nosuid Blocks `setuid`/`setgid` binaries from running.
nodev Ignores device files (e.g., `/dev/null`) on this filesystem.
noatime Disables access time updates to improve performance.
nodiratime Disables directory access time updates (for performance).
relatime Updates access time only if the file is modified, balancing performance.
strictatime Always updates access time (not recommended for performance reasons).
sync Writes changes to disk immediately instead of caching them.
async Writes changes to disk asynchronously (default, better performance).
commit=600 Delays disk writes for 600 seconds (10 minutes), reducing wear.
nofail Allows booting even if the mount fails (useful for external drives).
errors=remount-ro If an error occurs, remounts the filesystem as read-only.

performance options
