I'm waiting on my vendor to respond to this (I opened a case with GTAC but apparently we bought these units through a partner that does the support instead), but I was wondering if anyone else had seen this and maybe had a workaround. I've got a pair of stacks - each is one 5420F-16MW-32P4XE stacked with one 5320-48P-8XE. I attempted to upgrade the stacks to 33.5.1.6, but the 5420s throw the error "Error: Failed to install image - mount: can't find /alt//exos in /proc/mounts" and their inactive firmware partition becomes inaccessible - even running "show version images" throws the error "Internal error --> history file open failed!"
I tried installing the previous firmware (32.7.3.15) onto the inactive partition, but that fails too. It seems like it might have killed the inactive partition's filesystem or something. This happened across both stacks, so it seems like it might be a bug - anyone else seen this?
These stacks are unfortunately remote, so I don't have the ability to easily get to them and run recovery via TFTP/serial.
