Natty: Either the lower file is not in a valid eCryptfs format

[coljohnhannibalsmith]

Hello,

I keep getting the following message in /var/log/messages:

May 17 14:20:58 sophie-laptop kernel: [ 9304.149148] Either the lower file is not in a valid eCryptfs format, or the key could not be retrieved. Plaintext passthrough mode is not enabled; returning -EIO

Can someone tell me what this message means and what to do about it

My file system was encrypted before the online-upgrade to Natty. I believe that it still is...






Thanks Hannibal

More Info:

eCryptfs is a POSIX-compliant enterprise-class stacked cryptographic filesystem
for Linux.

It provides advanced key management and policy features. eCryptfs stores
cryptographic metadata in the header of each file written, so that encrypted
files can be copied between hosts; the file will be decryptable with the proper
key, and there is no need to keep track of any additional information aside
from what is already in the encrypted file itself. Think of eCryptfs as a sort
of "gnupgfs".

eCryptfs is a native Linux filesystem. The kernel module component of eCryptfs
is part of the Linux kernel since 2.6.19.

This package contains the userland utilities.

Does this have anything to do with selecting to encrypt the Ubuntu partition during install

Also, can I uninstall it?





Thanks Hannibal

Do I need eCryptfs if I have my Ubuntu partition encrypted or can I remove it???




Thanks Hannibal

I know you asked this a while back, but no, you cannot remove it if you have an encrypted home directory.
