Hallo,
ich habe eine externe festplatte mit bestehender EXT4 Partition verschlüsselt. Dafür habe ich erst die Partition verkleinert (vermutlich auch mein Fehler):
resize2fs / dev/sdc1 2929710000
Danach die Verschlüsslung gestartet:
cryptsetup reencrypt --encrypt --type luks2 --reduce-device.size 32m /dev/sdc1
Nun kann ich die HDD auch wieder entschlüsseln, aber nicht mehr mounten! Gdisk zeigt mir folgendes an:
gdisk -l /dev/mapper/sdc-crypt GPT fdisk (gdisk) version 1.0.6 Warning: Partition table header claims that the size of partition table entries is 3165299386 bytes, but this program supports only 128-byte entries. Adjusting accordingly, but partition table may be garbage. Warning! Disk size is smaller than the main header indicates! Loading secondary header from the last sector of the disk! You should use 'v' to verify disk integrity, and perhaps options on the experts' menu to repair the disk. Caution: invalid backup GPT header, but valid main header; regenerating backup header from main header. Warning! One or more CRCs don't match. You should repair the disk! Main header: OK Backup header: ERROR Main partition table: OK Backup partition table: ERROR Partition table scan: MBR: protective BSD: not present APM: not present GPT: damaged **************************************************************************** Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but disk verification and recovery are STRONGLY recommended. **************************************************************************** Disk /dev/mapper/sdc-crypt: 23437737983 sectors, 10.9 TiB Sector size (logical/physical): 512/4096 bytes Disk identifier (GUID): C8A0204A-192A-4437-A6C1-CD127AC8699A Partition table holds up to 128 entries Main partition table begins at sector 2 and ends at sector 33 First usable sector is 34, last usable sector is 23437770717 Partitions will be aligned on 2048-sector boundaries Total free space is 2014 sectors (1007.0 KiB) Number Start (sector) End (sector) Size Code Name 1 2048 23437770717 10.9 TiB 8300
Wenn ich versuche es zu reparieren kommt:
Caution! Secondary header was placed beyond the disk's limits! Moving the header, but other problems may occur! Warning! Secondary partition table overlaps the last partition by 32768 blocks! You will need to delete this partition or resize it in another utility. Problem: partition 1 is too big for the disk. Aborting write operation! Aborting write of new partition table.
Gibt es noch die Chance das die Daten auslesbar sind? Vielen Dank für jede Hilfe!
