\"xming_logo\"R\u00e9cemment je devais agrandir un disque virtuel (VMDK) d’une machine Debian virtuelle tournant sous VMWARE ESXi.
\nLe cas de figure facile : un disque de donn\u00e9es que je peux d\u00e9monter en live, trifouiller, agrandir et remonter sur le syst\u00e8me. Par opposition au cas o\u00f9 c’est un disque\/partition utilis\u00e9 par le syst\u00e8me : \/, \/var etc.<\/em><\/p>\n

Sauf que d’habitude, arriv\u00e9 \u00e0 l’\u00e9tape avec l’outil parted<\/code>, \u00e7a se passe bien, je peux agrandir. Ben pas l\u00e0. J’en suis venu \u00e0 gparted<\/code> car lui fait ce qu’il faut pour contourner le probl\u00e8me. Ca m’a \u00e9vit\u00e9 des lignes de commandes tordues (certainement avec tune2fs ou debug2fs) et un risque certain de foirer mon disque, aussi virtuel soit-il…<\/p>\n

Et ce billet sera juste un rappel : m\u00eame sur une machine mode texte, sans interface graphique, on peut quand m\u00eame utiliser les outils graphiques, m\u00eame depuis un poste Windows (mon cas pr\u00e9sentement). Ce d\u00e9port d’affichage existe depuis des d\u00e9cennies sous Linux et on l’oublie un peu parfois.
\n<\/strong><\/p>\n

La manip d’agrandissement<\/h2>\n

En quelques mots, j’ai d\u00e9mont\u00e9 le disque, l’ai agrandi depuis vSphere. Au niveau syst\u00e8me, le linux ne voit rien tant qu’on ne scanne pas \u00e0 nouveau les disques. A une \u00e9poque, je me souviens d’un outil type rescan-scsi-bus, je ne sais plus trop ce qu’il en est, mais on peut forcer \u00e0 relire les caract\u00e9ristiques de tous les disques simplement :
\nfor i in \/sys\/class\/scsi_device\/*
\ndo
\necho 1 > ${i}\/device\/rescan
\ndone<\/code><\/p>\n

A ce moment l\u00e0, avec un print free<\/code> sous parted<\/code>, on voit bien les partitions et l’espace vide derri\u00e8re.
\nOn peut tenter d’agrandir :
\n
\nparted \/dev\/sdX
\nresize 1<\/code>
\npuis indiquer la position de d\u00e9part (la m\u00eame qu’actuellement)
\npuis indiquer la position de fin, \u00e0 priori le bout du disque qu’on vient d’agrandir.
\nSauf que moi, \u00e7a me sortait l’erreur suivante :
\n(parted) resize 1
\nWARNING: you are attempting to use parted to operate on (resize) a file system.
\nparted's file system manipulation code is not as robust as what you'll find in
\ndedicated, file-system-specific packages like e2fsprogs. We recommend
\nyou use parted only to manipulate partition tables, whenever possible.
\nSupport for performing most operations on most types of file systems
\nwill be removed in an upcoming release.
\nStart? [1049kB]?
\nEnd? [42,9GB]? 75,2GB
\nError: File system has an incompatible feature enabled. Compatible features are has_journal, dir_index, filetype, sparse_super and large_file. Use tune2fs or debugfs to remove
\nfeatures.
\n<\/strong>(parted) quit<\/code><\/p>\n

Et comme gparted<\/code> se d\u00e9brouille tr\u00e8s bien de cela, je me suis dit que j’allais l’utiliser \u00e0 distance.<\/p>\n

Le d\u00e9port d’affichage avec gparted et XMing<\/h2>\n

J’ai donc ressorti ce bon vieux XMing – qui est donc un serveur X pour Windows – que j’ai lanc\u00e9 avec autorisation d’afficher tout ce qu’on lui pr\u00e9sente (\u00e9quivalent du xhost +<\/code>, cf. plus bas), soit en le lan\u00e7ant comme suit : xming.exe -multiwindow -ac<\/code>. C’est le \u00ab\u00a0-ac\u00a0\u00bb qui fait tout le boulot \ud83d\ude42
\nDe l\u00e0, j’indique au serveur Linux de d\u00e9porter l’affichage vers ma machine (Windows) : export DISPLAY=m.o.n.ip:0.0<\/code>, je lance gparted et \u00f4 miracle, j’ai la fen\u00eatre graphique sur mon Windows \ud83d\ude42<\/p>\n

Et si vous attaquez le serveur depuis une machine Linux, vous pouvez tout simplement indiquer un DISPLAY \u00e9gal \u00e0 votre PC, en autorisant l’affichage d’applications venues d’autre part. De mani\u00e8re bourrine un xhost +<\/code>, et pour \u00eatre plus finaud… lisez man xhost<\/code>.<\/p>\n

Voil\u00e0 voil\u00e0, ticket rapide mais qui peut rendre service. Du moins je l’esp\u00e8re.<\/p>\n","protected":false},"excerpt":{"rendered":"
