Hello!
I wanted to change & update the swap-endpoint on my DappNode Bee Package, but it didn’t response anymore after hitting update and since that „Update“ Button in Config section is staying greyed out and unclickable.
Additionally I noticed several times already that the backup didn’t work of my bee files because of some unauthorised read only temporary file system. Also Reboot Buttons, etc. failed, though the menue of the interface load quite fast. After rebooting with alt+ctrl+del the Update button still is greyed out. Everything else is for now back to normal again, but I can’t change the endpoint.
Please help!

Added: Today I noticed following lines on the screen output of my Pi after DAppNode login:
[31052.794983] EXT4-FS error (device mmcblk02): ext4_mb_generate_buddy:747: group 344, block bitmap and big descriptor inconsistent 24759 vs 26307 free clusters
[37508.237546] EXT4-FS error (device mmcblk02): ext4_mb_generate_buddy:747: group 420, block bitmap and big descriptor inconsistent 17065 vs 17064 free clusters

Is it possible my SDcard is already broken after a few days running bee on DAppNode? Is there any chance to fix this, or do I have to buy a new MicroSD and reinstall everything? (Fortunately I‘ve made a backup of my bee data)
