I have a TrueNAS install with SMB turned on and nothing else. Even when it’s idle and nothing is accessing it, there’s constant disk activity. Very low bandwidth, but it’s like some log is in verbose mode.
TrueNAS is installed in a NVMe disk with plenty of room, and there’s only one pool. I’ve checked my snapshot configuration, nothing enabled faster than daily.
What could be causing it? How do I stop it or redirect it to the NVMe drive? I’m willing to create a partition on the NVMe drive if that’s what will do it.
Edit: thanks everyone for all the feedback, I’ll try these out and report back.
Or set up a ramdisk, or turn off log to disk entirely somehow. But if you do that, you’ll lose logs between reboots or crashes, making troubleshooting harder.
