'shutdown' command causing unclean shutdown

Hi, hope you can help. I keep getting the error "unclean shown down detected" on booting up, requiring an fsck.

I'm running a nightly backup script, which when finished immediately issues the command:
sudo shutdown -h now
Could this be causing the unclean shutdown, but shutting down immediately after a lot of writes to the HDD?

I've cycled through some 'normal' restarts in KDE and I don't get the error. Could it be the above shutdown command? Would simply delaying the shutdown fix this issue?

Have you shut down the machine in the past and not received that message? If so, how did you do it?

Do you receive the same if you restart (shutdown -r now)? It should use the same process.

Could it be that a flag is not being set, registering the machine as having shutdown uncleanly, though the incident in question has long since passed?

You might try some "sleep" between the end of the backup and the shutdown command to enable write cache to be flushed (if this is a bash script).

Try issuing a couple of
cmds to force buffer flushing. System should do it anyway, but no harm in making sure.
