Dear list, $ mkdir foo && touch foo/bar && mkfs.erofs foo.erofs.img foo mkfs.erofs 1.7.1 <E> erofs: failed to build shared xattrs: [Error 61] No data available <E> erofs: Could not format the device : [Error 61] No data available That is at a location backed by BTRFS (btrfs-progs v6.7.1) on kernel 6.8.0.
If I use a TMPFS-supported folder instead all goes well. Of course (NB "-x-1"), $ mkdir foo && touch foo/bar && mkfs.erofs -x-1 foo.erofs.img foo also works but is not how mkfs.erofs is meant to work in the general case. Kind regards, Gaƫl
