Hello,
I recently cloned my OMV-installation onto another USB-stick. To do that I bootet into a live-cd and used the command if=/dev/sdx of=/dev/sdy bs=4K . It all went fine and worked for weeks.
Yesterday though the system would not boot anymore. It gave me the following error:
error: file '/boot/grub/i386-pc/normal.mod' not found.
Entering rescue mode...
When I tried to fix the problem using a Linux live-cd I discovered that the file system on the USB-stick was damaged and I could not repair it with fsck either.
I then went for the easiest solution and cloned the old USB-stick again onto the new one. OMV then bootet again.
I then decided to update it but could not do it since it told me that "/var/cache/apt/archives/partial" was read only. I already assumed that I'm back into trouble and wondered if the root-filesystem is damaged again. To find out I initiated a reboot and sure enough I received the "error: file '/boot/grub/i386-pc/normal.mod' not found."-error again.
Before all this I had tested the new USB-stick with H2testw for errors, but it looked all good.
Does anyone have any clue what's going on?
Thanks for reading!
*EDIT* I once again checked the USB-stick with H2testw and it tested it successfully.
