I was in a hurry and I had to stop there, but I suppose this kind of "block" (sorry I had no time to investigate what process was still using /dev/md0) should be addressed late this week I'll be able to work on this again, I plan to start Guix from the USB install media and use it as a rescue disk to complete the grub-install on the physical devices: I've done this kind of fixes several times with several rescue-distros, I should have no problem using Guix this time as a side note: what about raplacing mdraid with brtfs? I have not much experience with btrfs (especially as a boot filesystem) so I tend to be conservative and use what I know (and is maybe more mature?) ...anyway: is btrfs formatting using raid1 (or raid10) mode supported using the Guix Graphical Installer? last but not least: should we add a guided RAID partitioning method to the Graphical Installer? thank you Guix! =2D-=20 Giovanni Biscuolo Xelera IT Infrastructures --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEERcxjuFJYydVfNLI5030Op87MORIFAlzRxlIACgkQ030Op87M ORJvzg//e6XjWqrKYNoqYPbjGRc5aBUd3G/SYMbuZvmlPsnlsb4POiLLcs50YRF1 FbedlMATwxG9L8OfgKuiGTfm85bJ9Si0FNXadBfJ1BBiPdPVWk9X8JJCKob+/8i4 9YFGP3E90P8wGdsVDF71CU/mzyWIb/7ac4A8MNZYyGDfy595Lx4BvKB/KTW7RE8H o7n4HU/m8Bxko8RWojgGYQsceXTUIg9p8HVSVT+RVmpbJ0RzIIUM919ByRNsZgm6 Ky4i4RKUftKpvuKVNmqfFnie3fOHfOgpt86qmlAjxx/HXL6/1y1X73H2fD5wdQu0 gc1YO+IUMtWCHTKSaqlhna5qayTMfT75qaWCKbU/+YQ1MjrlHFlVVUE1QiDAOZpa 0tvRVB7YNw9617WRRyyONFXGqFWBgDNJgrR0QeHYPYAe9XxV9lHJFDdSaZ030mxY kHYw1mbEjuVG73+0HB5xUvTAcwNpiKnhCzv7cxXQOb4Refl5GxetHIKG8TaI5HKM UDbWHCUKJ2C9rTYmcVBQZbhU3+dkhXwHW1BVdN4lgUIlXGdALOZPORv3i1pVTtcS u4Q5c6XjPthVhUvfSowmcFu/wTl9hlUV1Kd2f/q2sQEoFx6ltPkXSzN0vOawacce Piw71ZjtFkaqtf9PpmL2GV8ZdWexL1RJ0Aa/K4e4JPOEbq0IefI= =mujK -----END PGP SIGNATURE----- --=-=-=--
