[gentoo-user] No access to encfs-encrypted directory

[meino.cramer@gmx.de]

Hi,

On a extf4 formatted partition I have two directories (beside others,
non encrypted ones):

    .crypt
    crypt

.crypt contains the encrypted data.

I then mount the encrypted partionas as root with

    mount -t ecryptfs /home/user/.crypt /home/user/crypt -o ecryptfs_cipher=blowfish,ecryptfs_key_bytes=56,ecryptfs_passthrough=n,ecryptfs_sig=XXXXXXXXXXXXXXXX,ecryptfs_fnek_sig=XXXXXXXXXXXXXXXX,ecryptfs_unlink_sigs,key=passphrase

(I blanked the sigs before posting)

This worked like a charm....but...

A local power fail switches my PC off while the encrypted directory
was mounted.

After rebooting I still was abler to execute the command given above
successfully, but two diorectorie below the directory 'crypt' show
like this:

drwxr-xr-x  6 mccramer users  4096 2012-01-07 05:05 .

d?????????  ? ?        ?         ?                ? logdata
    

Trying to cd into logdata or .process fail.


Is there any chance to recover from this and if yes: how ???

Thank you very much for any help in advance!

Best regards,
mcc
