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
- How do I fix this?
- How do I prevent this happening in the future?
I'm using Ubuntu 10.10.
