My home directory is encrypted using ecryptfs. I have recently started getting I/O errors when I try to access some files on that file system:

aix@aix:~/.evolution/mail/imap/acct/folders/INBOX$ cat 130395.HEADER
cat: 130395.HEADER: Input/output error

/var/log/messages has the following to say:

Oct 11 11:05:38 aix kernel: [138537.991670] 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

Two questions:

  1. How do I fix this?
  2. How do I prevent this happening in the future?

I'm using Ubuntu 10.10.
