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

[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)

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.
