Ubuntu
ecryptfs-utils package

Filesystem looks OK, but log messages "Valid eCryptfs headers not found in file header region or xattr region"

Asked by Steffen Neumann

Binary package hint: ecryptfs-utils

Hi,

I keep accumulating messages about eCryptfs in the logs,
although the filesystem works as expected. But I guess
the constant writes slow down my system quite a lot.

The closest related bug report seems to be "#372014 errors in dmesg",
but that was closed with "fix released", so I am opening a new report here.

Yours,
Steffen

Partition is mounted as:
/home/.../Private on /home/... type ecryptfs (ecryptfs_sig=bd...f7,ecryptfs_fnek_sig=8b..db,ecryptfs_cipher=aes,ecryptfs_key_bytes=16)

System is an up-to-date (including karmic-proposed) karmic:

You have some zero byte files, most likely.

find $HOME/.Private -size 0

You can probably remove these, as they are empty, and likely trash at this point.

Just got bit by this one. Should eCryptfs be improved to autorecover and delete these empty files automatically? I could see this causing intermittent problems in a production environment once a volume runs out of space.

Can you help with this problem?
