Re: Unmount and mount a mass storage from shell

I think that you will always need to inform the UEFI Shell of the change.  It is not designed to automatically do detection of added/removed/changed devices.

I think that your solution to use the code from mount makes the most sense.

Hi Jaben, Thanks a lot for input. My necessity for unmount-mount is that, the USB client is a Linux storage gadget, which needs to be remounted to get the updated/new files created by Linux. Anyhow, now I'm doing this programmatically by copying mount command code from older shell. :)

One more issue is that, after Linux updates some file (on client side, Linux will mount the same partition, save some file, and then umount the partition. Then if i remount the partition on Host side, when host is windows, i will get updated files) I will manually remove and connect the cable (MS device), UEFI is not able to detect the MS itself. (This issue observed, regardless of remount. This issue is not there on windows 10 host).
Can you give some pointers on this?

Thanks a lot, Jaben.

Regards,
Keshava

You can "disconnect" the driver
You can do "map -d" to delete a mapping

I am unsure what your goals are for mount/unmount
