Hey Everyone, This might be worth a good laugh. tl;dr version: filesystem is about 100 blocks too big for the device, not sure why. - mount says fs is too big for device - fsck says fs is too big for device - resize2fs says to fsck - fsck says it's ok - resize2fs says to fsck I can see the contents under testdisk. It's nothing which isn't backed up elsewhere. It's a 1.5TB filesystem, so it can be slow to work with. The plan was to check what I put on it and repurpose the disk. At this point I'm thinking I'll use testdisk to poke around then repartition and reformat. Any thoughts about this?
