White Blank Screen After Pi-hole Freeze and Reboot Loop

[deHakkelaar]

When your Pi freezes for no apparent reason:

500 Internal Server Error

Does below one show any Under-voltage messages? sudo journalctl --full --no-hostname --pager-end --grep voltage If so, have a look below: If you see warnings, switch to a higher quality power supply and cable. Low quality power supplies can corrupt storage or cause unpredictable behaviour within the Raspberry Pi. https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#power-supply-warnings

Is there a way to skip the disk check or fix this within Raspbian?

If you connect a screen, you should see the disk check being performed on screen during boot.
Or at least a mention of it being performed.
If you dont see any boot output on screen at all, the boot sequence didnt get that far yet to do the disk check.

Could I disconnect the SSD and validate it on my Debian PC to resolve this?

Yes you can.
You can list detected block devices (disks or partitions) plus their mountpoints with below:

$ lsblk -p
NAME             MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
/dev/mmcblk0     179:0    0 14.8G  0 disk
├─/dev/mmcblk0p1 179:1    0  256M  0 part /boot
└─/dev/mmcblk0p2 179:2    0 14.6G  0 part /

Search on the net how to use the fsck command:

man fsck

EDIT: Dont forget to unmount first (umount) if it shows mounted with the lsblk command!
