EXT4-FS error (md0) ext4_iget:4429 / No response from system

[valvius]

hey

i experienced some issues within the boot process. It took me sometimes 3 or more runs until the system was usable.

Now it boots and shows me the login mask but there isn't any response to my keystrokes. Web and SSH aren't working, too.

 

I recieved this output in debug mode:

EXT4-fs (md0): synoacl module has not been loaded. Unable to mount with synoacl, vfs_
EXT4-fs (md0): warning: mounting fs with errors, running e2fsck is recommended
EXT4-fs (md0): mounted filesystem with ordered data mode. Opts: barrier=1
EXT4-fs (md0): re-mounted. opts: (null)
EXT4-fs error (device md0): ext4_iget:4429: inode #41: comm sh: bogus i_mode (0) 
init: syslog-ng pre-start process (13084) terminated with status 2
EXT4-fs error (device md0): ext4_iget:4429: inode #41: comm sh: bogus i_mode (0)
init: rc pre-start process (13084) terminated with status 2

NAS login:

 

I can't run e2fsck because i can't login.

Is there anybody with an idea how to fix this or at least how i can get my missing data?
