bonsoir J'ai voulu profiter de la baisse de température pour offrir une nouvelle machine à ma Debian (kit complet boîtier, carte mère RAM, un don de mon employeur d'une machine décommissionnée pour absence de support W11). Ma Debian est une version stable amd64 D'habitude, je prends le disque de l'ancienne machine, je le mets dans la nouvelle, et pouf ça marche. Enfin ça démarre ; après faut mettre les drivers à niveau, mais ce n'est pas le sujet Seulement depuis que j'ai l'ancien boîtier j'ai migré mon système sous RAID1, qui fonctionnait sans pb sur l'ancienne machine. Là ça ne démarre pas, il bloque après Grub sur un message mdadm : "No device listed in conf file where found" répété plusieurs fois Puis Alert UUID-machin not found, dropping to a shell donc busybox initramfs J'ai booté sur systemrescuecd 12.01 où j'ai pu monter et vérifier les partitions RAID. Donc un changement de machine ne fait pas perdre le RAID. un blkid m'informe que l'UUID de la partition "manquante" est /dev/md127 correspondant à / Le BIOS me confirme avoir correctement détecté les deux disques du RAID. Systemrescuecd aussi. Je suis en legacy boot, systemrescuecd également, donc pas de pb de là. Je manque d'idée, je suis preneur des vôtres. Je vous joins à toute fin utile un blkid et la config mdadm : BLKID : > /dev/loop1: BLOCK_SIZE="524288" TYPE="squashfs" > /dev/md127: LABEL="/ quietty" > UUID="6b73ab49-5d8d-4cbe-88a1-a127f33c21e5" BLOCK_SIZE="4096" TYPE="ext4" > /dev/sdb4: UUID="6fa5e6c8-bc1d-4f2e-28f5-a35fad0ce707" > UUID_SUB="57e97a89-306a-284b-c23d-8b2283a4038d" LABEL="quietty:3" > TYPE="linux_raid_member" PARTUUID="c878eefe-04" > /dev/sdb2: UUID="fb2ad272-7978-d66a-92aa-f11e6598c488" > UUID_SUB="b0240d48-a6b0-6b8e-1761-21b99796116b" LABEL="quietty:1" > TYPE="linux_raid_member" PARTUUID="c878eefe-02" > /dev/sdb3: UUID="5be537fd-deb7-2baa-6019-1d3fa8dc7267" > UUID_SUB="430cfd51-2527-fbfc-6afd-1facd9cda82e" LABEL="quietty:2" > TYPE="linux_raid_member" PARTUUID="c878eefe-03" > /dev/sdb1: UUID="fd36a04f-1e55-ea3b-bd30-1747ac5e5323" > UUID_SUB="d5574b21-6708-e703-6ac8-bbaff8c5d9c6" LABEL="quietty:0" > TYPE="linux_raid_member" PARTUUID="c878eefe-01" > /dev/md125: UUID="5108453d-57fe-4174-9d35-a7604688f1ff" > BLOCK_SIZE="4096" TYPE="ext4" > /dev/loop0: BLOCK_SIZE="2048" UUID="2025-05-26-11-36-03-00" > LABEL="RESCUE1201" TYPE="iso9660" PTUUID="3b254143" PTTYPE="dos" > /dev/sdc1: LABEL_FATBOOT="GLIM" LABEL="GLIM" UUID="E244-F931" > BLOCK_SIZE="512" TYPE="vfat" PARTUUID="cfbd527d-01" > /dev/md126: UUID="feff2889-d7ca-4bad-9c0d-52f38c5b7e89" > BLOCK_SIZE="4096" TYPE="ext4" FDISK > [root@sysrescue ~]# fdisk -l > Disk /dev/sda: 931.51 GiB, 1000204886016 bytes, 1953525168 sectors > Disk model: ST1000VN008-3CW1 > Units: sectors of 1 * 512 = 512 bytes > Sector size (logical/physical): 512 bytes / 4096 bytes > I/O size (minimum/optimal): 4096 bytes / 4096 bytes > Disklabel type: dos > Disk identifier: 0xe0353632 > > Device Boot Start End Sectors Size Id Type > /dev/sda1 2048 117186559 117184512 55.9G fd Linux raid > autodetect > /dev/sda2 117186560 156248063 39061504 18.6G fd Linux raid > autodetect > /dev/sda3 156248064 1132810239 976562176 465.7G fd Linux raid > autodetect > /dev/sda4 1132810240 1953523711 820713472 391.3G fd Linux raid > autodetect > > > Disk /dev/sdb: 931.51 GiB, 1000204886016 bytes, 1953525168 sectors > Disk model: ST1000VN008-3CW1 > Units: sectors of 1 * 512 = 512 bytes > Sector size (logical/physical): 512 bytes / 4096 bytes > I/O size (minimum/optimal): 4096 bytes / 4096 bytes > Disklabel type: dos > Disk identifier: 0xc878eefe > > Device Boot Start End Sectors Size Id Type > /dev/sdb1 * 2048 117186559 117184512 55.9G fd Linux raid > autodetect > /dev/sdb2 117186560 156248063 39061504 18.6G fd Linux raid > autodetect > /dev/sdb3 156248064 1132810239 976562176 465.7G fd Linux raid > autodetect > /dev/sdb4 1132810240 1953523711 820713472 391.3G fd Linux raid > autodetect > > > Disk /dev/sdc: 931.51 GiB, 1000204885504 bytes, 1953525167 sectors > Disk model: Expansion > Units: sectors of 1 * 512 = 512 bytes > Sector size (logical/physical): 512 bytes / 512 bytes > I/O size (minimum/optimal): 512 bytes / 512 bytes > Disklabel type: dos > Disk identifier: 0xcfbd527d > > Device Boot Start End Sectors Size Id Type > /dev/sdc1 2048 1953523711 1953521664 931.5G b W95 FAT32 > > > Disk /dev/md127: 55.85 GiB, 59963867136 bytes, 117116928 sectors > Units: sectors of 1 * 512 = 512 bytes > Sector size (logical/physical): 512 bytes / 4096 bytes > I/O size (minimum/optimal): 4096 bytes / 4096 bytes > > > Disk /dev/md126: 18.61 GiB, 19981664256 bytes, 39026688 sectors > Units: sectors of 1 * 512 = 512 bytes > Sector size (logical/physical): 512 bytes / 4096 bytes > I/O size (minimum/optimal): 4096 bytes / 4096 bytes > > > Disk /dev/md125: 391.22 GiB, 420070031360 bytes, 820449280 sectors > Units: sectors of 1 * 512 = 512 bytes > Sector size (logical/physical): 512 bytes / 4096 bytes > I/O size (minimum/optimal): 4096 bytes / 4096 bytes > > > Disk /dev/md124: 465.54 GiB, 499864567808 bytes, 976297984 sectors > Units: sectors of 1 * 512 = 512 bytes > Sector size (logical/physical): 512 bytes / 4096 bytes > I/O size (minimum/optimal): 4096 bytes / 4096 bytes > > > Disk /dev/loop0: 1.02 GiB, 1092157440 bytes, 2133120 sectors > Units: sectors of 1 * 512 = 512 bytes > Sector size (logical/physical): 512 bytes / 512 bytes > I/O size (minimum/optimal): 512 bytes / 512 bytes > Disklabel type: dos > Disk identifier: 0x3b254143 > > Device Boot Start End Sectors Size Id Type > /dev/loop0p1 * 0 2133119 2133120 1G 0 Empty > /dev/loop0p2 248 3127 2880 1.4M ef EFI (FAT-12/16/32) > > > Disk /dev/loop1: 903.15 MiB, 947023872 bytes, 1849656 sectors > Units: sectors of 1 * 512 = 512 bytes > Sector size (logical/physical): 512 bytes / 512 bytes > I/O size (minimum/optimal): 512 bytes / 512 bytes MDADM.CONF /dev/md124 (/) monté sur /mnt > [root@sysrescue /mnt/etc/mdadm]# cat mdadm.conf > # mdadm.conf > # > # !NB!
