Raspberry Pi Information
network
| Category | Value |
|---|---|
| IP address | 192.168.0.63 |
| Hostname | ronberrypi |
To Be Able to Ping the Raspberry Pi
ping ronberrypi.local
users
| username | password | groups | /mnt/storage |
|---|---|---|---|
| ronny | 2reishit2ara | sudo | |
| website | 2reishit2ara | www-data, sudo | /var/www, /home/website |
| ftpuser | 2reishit2ara | www-data, sudo | /home/ftpuser |
| librarian | 2reishit2ara | librarian |
connect with a vnc
install
using the video you should be able to connect directly without doing anything special
connect tiger vnc
- hostname: ronberrypi.local
- then enter the username and password
connect realvnc
even easier
External Hard Drive Info
This table keeps track of the Raspberry Pi's external storage setup.
| category | value |
|---|---|
| device | /dev/sda2 |
| filesystem | ext4 |
| label | storage |
| mount point | /mnt/storage |
| mount options | defaults,relatime,commit=600 |
| UUID | 5bb54030-2df7-4798-afb5-bd2878ae0def |
Directory Bind-Mount Information
This table documents how key directories on the Raspberry Pi are linked to `/mnt/storage` and the commands used.
| Directory | Mounted From | Mounted To |
|---|---|---|
| /home/website | /mnt/storage/website | /home/website |
| /home/librarian | /mnt/storage/librarian | /home/librarian |
| /var/www | /mnt/storage/www | /var/www |
| /srv/n8n | /mnt/storage/n8n | /srv/n8n |
command used to bind target directory to mount point
sudo mount --bind /mnt/storage/<target_mount> /<bind directory>
example
- target mount: /mnt/storage/www
- bind directory: /var/www
making bind mounts persistent
To ensure the mounts persist after a reboot, add the following lines to `/etc/fstab`:
/mnt/storage/website /home/website none bind 0 0
/mnt/storage/calibre /home/calibre none bind 0 0
/mnt/storage/www /var/www none bind 0 0
/mnt/storage/n8n /srv/n8n none bind 0 0
Setup Commands
These commands ensure everything is correctly prepared before binding.
| Step | Command |
|---|---|
| Ensure storage directories exist | `sudo mkdir -p /mnt/storage/website /mnt/storage/calibre /mnt/storage/www` |
| Move existing data (if needed) | `sudo mv /home/website/* /mnt/storage/website/` |
| Create bind directories | `sudo mkdir -p /home/website /home/calibre /var/www` |
| Bind-mount directories | `sudo mount –bind /mnt/storage/website /home/website` |
| Add to `/etc/fstab` | `echo "/mnt/storage/website /home/website none bind 0 0" | sudo tee -a /etc/fstab` |
| Apply changes | `sudo mount -a` |
| Verify mount status | `df -h | grep storage` |
Hard Drive Commands
generally useful hard drive commands
| Purpose | Command |
|---|---|
| Find the UUID | lsblk -f |
| Check filesystem type | sudo blkid /dev/sda2 |
| Remount drive without rebooting | sudo mount -o remount /mnt/storage |
| Check if new options 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 Performance | defaults, noatime, nodiratime, commit=600 |
| Accurate File Access Times | defaults, relatime, commit=600 |
| Extra Safety in Case of Drive Failure | errors=remount-ro, nofail |
