[Pkg-zfsonlinux-devel] Bug#862271: zfs-linux: loop mounted files on zfs are read-only

[Vladislav Kurz]

Package: zfs-linux
Severity: normal

Dear Maintainer,

loop mounted files on ZFS are read only:

$ truncate -s 64G filesystem.img
$ mkfs.ext4 filesystem.img
$ mount -o loop filesystem.img /mnt
$ touch /mnt/test
touch: cannot touch ‘/mnt/test’: Read-only file system
$ mount -o remount,rw /mnt/
mount: cannot remount /dev/loop0 read-write, is write-protected

checking with mount, losetup shows that the loop filesystem is read only
It seems to be fixed upstream, please update to 0.6.5.10
