Hi Rich,
I am developing a patch for btrfs enhancement: btrfs-convert.
When I do test, run: make check tests, in dir
libguestfs/tests/c-api, I got these error:
0/516 test_btrfs_convert_0
libguestfs: error: btrfs_convert: /dev/sda1: block size is too small
conversion aborted.
FAIL: test_btrfs_convert_0
I also ran "btrfs-convert" command to deal with a 100MB img file
outside the guestfish, I got the same err msg, so it is a
litmitation of btrfs-convert
So my question is:
How to changed the default disk size, when do: make check tests
The tests/c-api/ tests use certain fixed size disks, to make those
tests run quickly (if we had to create new disks for every test,
they'd run very slowly indeed).
The fixed disk sizes are described here:
http://libguestfs.org/guestfs.3.html#adding-tests-for-an-api-action
If you want to write a more complicated test that requires a larger
disk, then you should put it into tests/btrfs/ instead.
In generator/actions.ml, leave the `tests' field out, and add a
`tests_excuse' line explaining that the tests are located in
tests/btrfs/.
Rich.
