@arcanicanis Yup, it’s an rPi running OpenWRT. This isn’t the first EXT4 file system I’ve had spontaneously explode. At a previous job we had one which held several hundred gigs of document scans bite the dust completely out of the blue. We switched to XFS afterwards.

I’ll have to look into F2FS! I don’t really dabble in the embedded linux world so I wasn’t even really aware of it haha
