Weird mount behaviour giving Input/output error

[Michael]

This only occured when I upgraded to release 81.

Basically this is my /etc/fstab

/srv/backup/originals /srv/rsync/data/originals ecryptfs r,key=passphrase:passfile=/root/ecryptfs_password,ecryptfs_sig=7ad5e0064d20e6c9,ecryptfs_cipher=aes,ecryptfs_key_bytes=16,ecryptfs_passthrough=no,ecryptfs_enable_filename_crypto=no,ecryptfs_unlink_sigs,ecryptfs_encrypted_view 0 0
/srv/backup/originals /srv/backup/originals ecryptfs rw,key=passphrase:passfile=/root/ecryptfs_password,ecryptfs_sig=7ad5e0064d20e6c9,ecryptfs_cipher=aes,ecryptfs_key_bytes=16,ecryptfs_passthrough=no,ecryptfs_enable_filename_crypto=no,ecryptfs_unlink_sigs 0 0

When I try to access either the encrypted or unecrypted view vI get
me@ubuntu-nas:/srv$ echo "hello world\n" > rsync/data/originals/hello.txt
-bash: rsync/data/originals/hello.txt: Input/output error
me@ubuntu-nas:/srv$ echo "hello world\n" > backup/originals/hello.txt
-bash: backup/originals/hello.txt: Input/output error

me@ubuntu-nas:/srv$ less rsync/data/originals/documents/codes/code.txt
rsync/data/originals/documents/codes/code.txt: Input/output error
me@ubuntu-nas:/srv$ less backup/originals/documents/codes/code.txt
backup/originals/documents/codes/code.txt: Input/output error

Now this is the weird bit
If I
me@ubuntu-nas:/srv$ sudo umount /srv/backup/originals
me@ubuntu-nas:/srv$ sudo umount /srv/backup/originals

It works as expected the encrypted view is encrypted, the normal view is decrypted, and file creation works properly.

me@ubuntu-nas:/srv$ sudo mount -a

  ecryptfs_unlink_sigs
  ecryptfs_encrypted_view
  ecryptfs_key_bytes=16
  ecryptfs_cipher=aes
  ecryptfs_sig=7ad5e0064d20e6c9

Breaks it again.

I'm seeing the same kind of error in my dmesg here, with ecryptfs-utils 81-0ubuntu3 in Karmic. If you need debugging, please just ask.

Tyler, you use ecryptfs in /etc/fstab, don't you?

Could you try the last released ecryptfs-utils and see if you can reproduce these problems?

[Michael (m-kucharski)]

The problem went away in a later release.
