Looks like the "-q" option also silences errors (wth?). Without "-q" option mkfs.reiserfs fails complaining that test.reiser_old.img is not a block device.
Running the following, also errors: LOOPDEV=$(losetup --show -f test.reiser_old.img) mkfs.reiserfs --format=3.5 -b 512 -l 'g;/éт 莭😁' "$LOOPDEV" Outputting this message: "Block sizes smaller than 4k are not supported." This contradicts the manpage, which says that block sizes may be between 512 and 8192. But this explains why the mount is having issues. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1943176 Title: Cannot mount 3.5 format made from mkreiserfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/reiserfsprogs/+bug/1943176/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
