 |
|
I've upgraded cryptsetup from 1.0.6 to 1.6.0. Now can't mount encrypted drive. What can i do? Is possible to mount drive created with older version ??? Thank You in advance.
| Code: | $ cryptsetup create data1 /dev/sda5
Enter passphrase: ...
$ mount /mnt/data1
mount: wrong fs type, bad option, bad superblock on /dev/mapper/data1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
|
dmesg:
EXT3-fs error (device dm-0): ext3_check_descriptors: Block bitmap for group 0 not in group (block 1521994086)!

| Since you are not using LUKS, you are preparing the volume with the default cipher, key size, etc. These defaults may have changed. Does it work if you explicitly specify the correct cipher and related values? |

| Read the source of the old version, or try to find some old documentation that tells you. |

| Code: | $ wget http://cryptsetup.googlecode.com/files/cryptsetup-1.0.6.tar.bz2
$ unp cryptsetup-1.0.6.tar.bz2
$ cd cryptsetup-1.0.6
$ grep -R DEFAULT_CIPHER *
src/cryptsetup.c: .cipher = opt_cipher?opt_cipher:DEFAULT_CIPHER,
src/cryptsetup.h:#define DEFAULT_CIPHER "aes" |
I found "aes", but i think that aes is used...
| Code: | $ cryptsetup status data1
/dev/mapper/data1 is active.
type: PLAIN
cipher: aes-cbc-essiv:sha256
keysize: 256 bits
device: /dev/sda5
offset: 0 sectors
size: 390636477 sectors
mode: read/write
$ mount /dev/mapper/data20 /dtemp/data1
mount: wrong fs type, bad option, bad superblock on /dev/mapper/data20,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
|
I don't know what to do with that...
Any suggestion ? |
