Resize de partition sous Debian 11

Fri, 21 Nov 2025 00:00:00 +0000

J’ai fini par réussir à augmenter la partition sous un VM Debian 11 ( sous Proxmox ) mais je suis jamais 100% sur de moi. J’oubli souvent la commande partprobe qui permet la confirmation du changement.

Débian : failed to load module mdraid: libbd_mdraid.so.2: cannot open shared object file: No such file or directory

Normalement d’après les forums il faut faire:

La premiere commande localise mon nouveau disque, avec la seconde j’ai plus de détail.

Pas de panique Débian est très fiable.

Michel, je te sais tout patraque depuis que tu as vu une série d’articles indiquant que Débian avait plus de faille que Windows:

Rock64 / Débian : Ajouter un disque dur externe

Thu, 12 Sep 2019 00:00:00 +0000

Je viens de prendre un disque dur externe car j’ai pas trop confiance dans les cartes SD ( désolé Michel).

Allocating group tables: done

A noter qu’en cas de crash durant le formatage, je conseille alors :
