I installed for the nth time OMV and I worked for a couple of weeks without problems.
There's only one user that I use to access shared folders from Windows.
Of course there is also the root and admin.
Last night I could not access with admin to turn off OMV.
I tried several times, changing the browser and turning off my PC.
With new and old password (openmediavault).
OMV continued to report a user eror or wrong password.
I finally connected directly from the console, as root, and made the poweroff.
OMV has shut down all services, but the server was still on and after a
few minutes I had to hold down the power button to turn it off.
This morning let me in without encounter any difficulties, but on the
console tells me error "Buffer I / O error", Journal errors, EXT4-fs errors, etc.
All errors on the USB device (Kinkston xFury 16GB).
I hope I can correct the problem without having to redo a new installation again or to change newly the device.
I also hope with version 3 will definitely solve the problem.
You can not install OMV on hard drives that today have a minimum capacity of 500GB or SSD of minimum 120GB, reserving to OMV the entire disk.
Nor we can go looking for old small-capacity disks just to avoid all this waste.
Thanks in advance for the advice.
