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
| performance status | mount options |
|---|---|
| maximum | defaults, noatime, nodiratime, commit=600 |
| accurate file access times | defaults, relatime, commit=600 |
| extra safety in case of drive failure | errors=remount-ro, nofail |
