SummitStack upgrade fails : "No space left on device"

[Gabriel3]

Hi everybody,

I'm upgrading my production SummitStacks from EXOS version 15.1.4.3 to 16.1.3.6.
The upgrade was successful on every stack except one, which fails and displays this error message :

Failed to download image on Slot-7 - tftp: can't open '/scratch/summitX-16.1.3.6-patch1-11.xos': No space left on device

It's a 8-member stack, i tried to launch the upgrade several times and it always fails on Slot 7.

Here is the complete output displayed in CLI :

Slot-1 # download image X.X.X.X extreme/summitX-16.1.3.6-patch1-11.xos vr vr-Default secondary
Do you want to install image after downloading? (y - yes, n - no, - cancel) Yes

I rebooted the slot 7 but it doesn't solve the problem.
I even tried to remove slot 7 from the stack, do "unconfigure switch all" on slot 7 to put it back to factory default, and then put it back in the stack. The issue is still here.

I wonder if any of you ever faced this problem.
Thanks in advance for the help

BootROM rescue, as Dave mentions, will wipe all of the memory on the switch as a part of the process. This is also a valid solution.
