SG 1000 stuck in boot loop after initial configuration

  • One of my SG-1000s is stuck in a boot loop. Previously the webconfiguration GUI worked fine, and I was also able to connect via USB. Now all I can figure out how to access is the uboot loader. Frankly, I'm stumped.

    On another known-good device the following step is

    Starting PFLOG...done.

    Any help would be greatly appreciated. Thanks!

    That looks like file system corruption. Please try running a file system consistency check. Here's how to do it:

    1. At the console press any key to interrupt the boot loader when you see:
      Hit [Enter] to boot immediately, or any other key for command prompt.
      At the prompt enter: boot -s
      That will boot in single user mode to a question asking for a path to the shell, just press return to reach the # prompt.

    2. At the # prompt run the following command:
      /sbin/fsck -y /

    Run the fsck command at least 6 times; Repeat the command until no errors are reported, even if fsck claims the filesystem has been marked "clean".

    1. Reboot by running: /sbin/rebootThe fastert way to get you back up and running is to re-install.

    That should do it but if it's a larger filesystem issue, fastest way to get you back up and running is to re-install. Here's how to do that

  • I'm guessing you had an ungraceful shutdown.

    I suspect this newer version of BSD or PFsense is leaving file data cached and if it goes down those writes go to etherspace. I've found you have about a 70% chance of file corruption if you pull the plug. From my experience this did NOT use to be the case. It is now!

    I've had 2 different boxes go corrupt from this. The one box a couple years old and this is a new occurrence. Needless to say, I have a UPS running properly now. Mine was an old UPS with no way to command a graceful shutdown. So every once in awhile the batteries would die with now one around to shut it down.

  • @ivor That worked. I was in the wrong prompt and it was telling me boot -s wasn't a command. Thank you for the help!

    You're welcome, glad I could assist!
