  • 1.  EX4200 Boot Loop

    Posted 12-05-2021 06:12
    Hi all,

    I have an EX4200 in a lab environment which recently lost power. Unfortunately after the reboot, one of my switches in a virtual chassis started having issues.

    The switch appears to boot perfectly ok, with what I can tell no distinct errors. However after reaching the login prompt, roughly 10-20 seconds the system calls a reboot and the switch enters a reboot loop. You will also see that it records the reboot as normal.

    So far I have reinstalled the firmware:
    15.1R7-S6.3 (current firmware and firmware installed when issue started)
    12.3R1.7 (tested older firmware) the log captured is from this, but otherwise it is exactly the same symptoms. 

    One thing I have spotted:
    On 12.3: path /var/jail does not exist Automatic reboot in progress...
    On 15.1: Error execution /packages/mnt/jweb-ex-15.1R7-S6.3/mount.post: path /var/jail does not exist Automatic reboot in progress...

    Wondering if anybody has any ideas on what the issue might be? Could J-Web be the issue?

    I have also opened the switch as I thought maybe I could swap an SD-Card or CMOS battery, however nothing seems replaceable.

    12.3 log:
    syncing disks... Syncing disks, buffers remaining... 4 4 3 3 3 3 1 1 0 1 1
    Final sync complete
    2 0 Uptime: 3m12s
    recorded reboot as normal shutdown
    Rebooting...

    This is why they have the dual boot partitions. With power fail reboots, often at least one member boots from its backup partition, and that can break the vc stack if you haven't previously after a system update done "req sys snap slice alt" to get the  new OS copied onto the backup partition.

    Or, when you do have a boot problem, you can at the bootloader tell it to reboot from the other partition, or "slice". (But I don't remember the exact command for that, and don't have any 4200s online anymore. But ? at boot loader prompt should point you to it.)
