bonjour !
so I downloaded and installed yesterday 18.2R3S2 on 237 Juniper Ex2300-C that I have in test, following the official release last friday. so ...

Start time 2019-12-02 09:10:04 EST
Uptime 1 day, 1 hour, 27 minutes, 34 seconds
Last reboot reason Router rebooted after a normal shutdown.
remember that on all those switches, the miniusb console port is disabled. So I expect the combination of the new image and the miniusb disabling to protect my lab from the zombi switches AND the swizzle reboot. if everything hold until after the holdays, then I am on to disassembling the lab and deploy the switches.
so it's been only a day - nothing special to report.
well, just 2 things ...
1) a month ago, when I made the pre-release installation, I was confronted with a majority of switches giving me a minor alarm of Minor RE 0 /var partition usage is high. I was surprised because most of the switches showed it. SR to JTAC and they advised me to do a request system storage clean-up. I ended up doing it on all my switches before installing the new image and now the alarms are gone. I am watching for alarms, but all my yellow leds are off 🙂
2) my procedure to image upgrade is to ftp the image on the /tmp directory of the switch, and do a software add with the options force unlink no-copy reboot. I tried a couple of times to copy the image on /var/tmp directory as the procedure suggest

Copy the jinstall package to the router. We recommend that you copy it to the /var/tmp directory, which is a large file system on the hard disk.
... but I kept running into space issues that no storage spasce cleanup could solve. I then went back to this trick I learned las july of using the /tmp directory.
I'll keep an eye open and post from time to time where I am exactly in my test. even good news are worth posting ! I also long to get the release document to read with my own eyes that PR1442376 is solved . I'll probably frame it.
by the way, if you are curious as to how I upgrade 237 switches, I have all their names and IP adress in Excel. I generate 237 small batch files that I execute with a click and that ftp a .sh file on each switch. I then use SecureCRT to open a bunch of ssh, issue a common storage space cleanup, and execute the .sh file that issue 2 cli commands: one is to get the image from ftp, the second to do the software add with the options. It worked the first time on all my switches !!!
I will try again with Junos Space, but I gave up using it for this last summer: for exemple, staging the image was alaways done in the /var/tmp directory, and asking to install it failed most of the times.
