ecryptfs-utils mounting problem

I am trying to setup a Private directory within a home folder. I am using this documentation: https://wiki.archlinux.org/index.php/Sy … h_eCryptfs
I did this after installing ecryptfs-utils:

 
[root@ARCH306 ~]# modprobe ecryptfs
[root@ARCH306 ~]# mkdir -m 700 /home/whoop/.Private
[root@ARCH306 ~]# mkdir -m 500 /home/whoop/Private
[root@ARCH306 ~]# chown whoop:users /home/whoop/{.Private,Private}
[root@ARCH306 ~]# mount -t ecryptfs /home/whoop/.Private /home/whoop/Private
Select key type to use for newly created files: 
 1) passphrase
 2) openssl
Selection: 1
Passphrase: 
Select cipher: 
 1) aes: blocksize = 16; min keysize = 16; max keysize = 32 (not loaded)
 2) des3_ede: blocksize = 8; min keysize = 24; max keysize = 24 (not loaded)
 3) cast6: blocksize = 16; min keysize = 16; max keysize = 32 (not loaded)
 4) cast5: blocksize = 8; min keysize = 5; max keysize = 16 (not loaded)
Selection [aes]: 1
Select key bytes: 
 1) 16
 2) 32
 3) 24
Selection [16]: 1
Enable plaintext passthrough (y/n) [n]: n
Enable filename encryption (y/n) [n]: y
Filename Encryption Key (FNEK) Signature [XXXXXXXXXXXXX]: 
Attempting to mount with the following options:
  ecryptfs_unlink_sigs
  ecryptfs_fnek_sig=XXXXXXXXXXXXX
  ecryptfs_key_bytes=16
  ecryptfs_cipher=aes
  ecryptfs_sig=XXXXXXXXXXXXX
WARNING: Based on the contents of [/root/.ecryptfs/sig-cache.txt],
it looks like you have never mounted with this key 
before. This could mean that you have typed your 
passphrase wrong.

Would you like to proceed with the mount (yes/no)? : yes
Would you like to append sig [XXXXXXXXXXXXX] to
[/root/.ecryptfs/sig-cache.txt] 
in order to avoid this warning in the future (yes/no)? : yes
Successfully appended new sig to user sig cache file
Error mounting eCryptfs: [-5] Input/output error
Check your system logs; visit <http://launchpad.net/ecryptfs>

As you can see I get a Error mounting eCryptfs: [-5] Input/output error but it seems to be mounting anyway. I put a testfile in there then 'umount /home/whoop/Private'. I found some encrypted files in /home/whoop/.Private when I remounted using: 'mount -t ecryptfs /home/whoop/.Private /home/whoop/Private' I got the same error again.
/var/log/everything.log shows this info:
Apr  3 17:18:56 localhost mount.ecryptfs: Failed to write to the mount table
Apr  3 17:29:23 localhost mount.ecryptfs: Failed to write to the mount table

Re: ecryptfs-utils mounting problem

I believe it's due to /etc/mtab being a symlink in Arch these days. There's a report on the bugtracker with more information, I think it should've already been solved in ecryptfs-utils.

You need to install an RTFM interface.

Thanks for the info.
I don't think it has been fixed as this was just performed on a fresh installed machine...
