Hi everyone,
I have the latest version of OMV 4.
I have the autoshutdown plug-in that put my NAS in sleep mode. I then wake it up using the wake up plug-in with WoL packet.
When it happen the file system of OMV sometimes goes into read only mode.
This is an example of what I get if I do an apt-get update from ssh:
Code

Err:3 file:/var/cache/openmediavault/archives Packages
Could not create temporary file for /var/lib/apt/lists/partial/_var_cache_openmediavault_archives_Packages - mkstemp (30: Read-only file system)

The only solution is to reboot my nas 
How can I solve this? With OMV3 I never had this problem..
