So this NAS hasn't been making me happy. See my previous problems: http://mybookworld.wikidot.com/forum/t-652893/unbricked-mbwe2-powers-off-when-2nd-drive-inserted
Anyway, after that problem, it worked fine for a while.
Yesterday I booted it, but could not access it.
I let it run overnight, and indeed today it's accessible.
In Explorer I can see the SAMBA shares, but Public and Download are inaccessible, Configuration opens fine.
I can SSH into it, but don't know what to look for.
I can go into the webinterface, this works OK, except for Storage - Disk Manager, Storage - Volumes and RAID management.
In System Status it says: DataVolume Usage: Failed
This all gives me the feeling that my data partition is not functioning correctly.
I have backups of the data, no problem, but I just want to get this thing working properly!
I just asked it to reboot in the webinterface.
Now it is showing the progress bar "Starting system now…".
Probably it will jump the percentage up and down, perhaps tomorrow I will know more…
