Can't Restart After Power Outage

Home Assistant Supervised in Raspberry Pi 4B
Home Assistant Core: 2022.5.5
Home Assistant Operating System: 8.0
After a power outage, the SD card for Home Assistant can’t reboot in all my 3 Raspberry Pi, but other SD card can reboot in the Raspberry Pi used for Home assistant. It means the Pi is ok and there are some problems in the SD card. Check the SD card in other Ubuntu system:

   8         1427456       249737182   118.4 GiB   8300  hassos-data

All other 7 partitions can be mounted except /dev/sda6(hassos-bootstate):

# mount /dev/sda6 /mnt/ha_test/ha6

mount: /mnt/ha_test/ha6: wrong fs type, bad option, bad superblock on /dev/sda6, missing codepage or helper program, or other error.

# fsck /dev/sda6
fsck from util-linux 2.34
e2fsck 1.45.5 (07-Jan-2020)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sda6

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem.  If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>
 or
    e2fsck -b 32768 <device>

I don’t konw if there are some problems in partition hassos-bootstate, if yes, how to repair? Many thanks!

Just start over, hopefully from a backup. SD cards are notoriously difficult to repair. I STRONGLY recommend using the Google Drive addon for backups.

It’s also recommended to have the HA device on UPS (along with your router), so a blackout doesn’t shut it down.
