First of all, I would like to let you know I come here cause I'm looking for a solution or a way to be able to mount the HOME partition and to read the inside data. I've been running Funtoo GNU/Linux on a **RAID 0 Fake Array** since I bought this computer in 2010, aprox. Yesterday booted into **SystemRescue** and tried to format every partition **except HOME** part. and I think something went wrong while formatting cause suddenly I started suffering the following issue. dmraid -ay RAID set "isw_bggjiidefd_240GB_BX100v2_5" was activated device "isw_bggjiidefd_240GB_BX100v2_5" is now registered with dmeventd for monitoring RAID set "isw_cfccfdiidi_640GB_RAID0" was activated device "isw_cfccfdiidi_640GB_RAID0" is now registered with dmeventd for monitoring **ERROR: dos: partition address past end of RAID device** RAID set "isw_bggjiidefd_240GB_BX100v2_5p1" was activated RAID set "isw_bggjiidefd_240GB_BX100v2_5p2" was activated RAID set "isw_bggjiidefd_240GB_BX100v2_5p3" was activated ls /dev/mapper/ control isw_bggjiidefd_240GB_BX100v2_5p1 isw_bggjiidefd_240GB_BX100v2_5p3 isw_bggjiidefd_240GB_BX100v2_5 isw_bggjiidefd_240GB_BX100v2_5p2 isw_cfccfdiidi_640GB_RAID0 In the previous scheme and directory, **logical partitions inside the extended partition are missing**.

Assembling the array through *mdadm* I can see every block device, but I can't mount HOME partition */dev/md/240GB_BX100v2.5_0p9*. I can mount the other partitions under the extended partition because I formatted them when assembled by mdadm. mdadm --examine --scan ARRAY metadata=imsm UUID=4f6eb512:955e67f6:5a22279e:f181f40d ARRAY /dev/md/640GB_RAID0 container=4f6eb512:955e67f6:5a22279e:f181f40d member=0 UUID=1f9b13e6:b6dc2975:9c367bbb:88fa3d2b ARRAY metadata=imsm UUID=c842ced3:6e254355:fed743f8:a4e8b8b8 ARRAY /dev/md/240GB_BX100v2.5 container=c842ced3:6e254355:fed743f8:a4e8b8b8 member=0 UUID=a2e2268c:17e0d658:17b6f16d:b090f250 ls /dev/md/ 240GB_BX100v2.5_0 240GB_BX100v2.5_0p3 240GB_BX100v2.5_0p6 240GB_BX100v2.5_0p9 640GB_RAID0_0p2 240GB_BX100v2.5_0p1 240GB_BX100v2.5_0p4 240GB_BX100v2.5_0p7 640GB_RAID0_0 imsm0 240GB_BX100v2.5_0p2 240GB_BX100v2.5_0p5 240GB_BX100v2.5_0p8 640GB_RAID0_0p1 imsm1 mount /dev/md/240GB_BX100v2.5_0p9 /mnt/ mount: /mnt: wrong fs type, bad option, bad superblock on /dev/md126p9, missing codepage or helper program, or other error. dmesg(1) may have more information after failed mount system call. dmesg [ 179.400010] EXT4-fs (md126p9): bad geometry: block count 92565760 exceeds size of device (92565504 blocks) But I can list every file using debugfs: debugfs -c /dev/md126p9 debugfs 1.47.0 (5-Feb-2023) debugfs: ls 2 (12) . 2 (12) .. 11 (56) lost+found 1712129 (16) joan 3670017 (12) tmp 4653057 (916) sys Home partition with mdadm & Gparted
