Thanks for testing it! What the commit does is lock the drive whose partition table is being modified. That sounds like a good idea in general. But parted does not expect the error code ENOMEM and thus misjudges the situation. See also: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit= /?id=3D88ce2a530cc9865a894454b2e40eba5957a60e1a for the fix that goes into Linux 5.9. We could also patch parted to also accept ENOMEM in addition to ENXIO if we wanted to. I wouldn't (it diverges from what upstream is doing--too much w= ork). --Sig_//wKapJIv6MOCvy19zhoZPww Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCgAdFiEEds7GsXJ0tGXALbPZ5xo1VCwwuqUFAl9jgIYACgkQ5xo1VCww uqV/dAf/Vw7MsIv2xeJ+IHCSgg7iH7NmI3xBnI7bbkH/7M+8dUlzQqtV4568uvF3 prWg4uLB5eqUiKYlySpqsGIgpuSnNtnhr8Uwg3B35s+GpjhOobWFCRqG7I0BMzyC FXLK+6cz8QX45eVXLRDynuhqZ5qEvLoViyLpXoAyJWoBRCZlTUHPCqIwrB4bnS3W i2kDCyLLjSUZI7Wpae4fFA9EUuDrl1PIMqjBOBNuy3t5vqZeewYAC2BKFy0H5pWD 6QQjzXHvzpi90BGPE6ghN3ycVQYHuEpOFbdjOxW6eC58OeFBWdsI8W/FIQLP9wMi DAsIDH6snbRP4k51eg69CI0KV3mFmg== =PtVk -----END PGP SIGNATURE----- --Sig_//wKapJIv6MOCvy19zhoZPww--
