Various logs and locations?

[GrahamBB]

I've looked for threads that detail the various logs, their locations, and ideally how to understand them.

Is there a resource for at least the locations of FreeNAS and BSD logs?

/var/log

What is it you need to know?

Specifically, I had a system email that we had a bad disk and want to go dig out which one, and the problem it's causing in the pool. By the time I was onsite and could [ull up the guid, the logs had rolled over and cleared!

In general, I think it would be very helpful to be able to dig and better understand some of the (e.g.) samba messages and master browser issues that we are still struggling to dig out.

You don't need a GUI to get to the logs. Enable ssh and connect remotely. You can monitor the logs or configure scripts to automate log backups.

yup we are sting in. My point was that we see the errors only in the GUI window, but they are erased every night at midnight. I'd welcome any pointers to a) learning about logs and how to read them, and b) best practices to manage logs.

Sorry that was sshing.

I suggest checking the smartctl output for each drive.

Are they erased or compressed and rolled over? If the latter, you can read older logs using bzcat.

A problem with the FreeNAS log rotation system is that it rotates at a certain, quite small, size and keeps a maximum of 4 compressed versions. So if something is filling a log quickly you may have logs only for a very short time. I don't know how often this is a problem in practice.

Underway with that!

Thanks

Where would those compressed logs be? I don't see them in /var/logs AFAIK.

They are in /var/log if you don't have any then your logs haven't rolled over.

Code:

[root@FreeNAS] /var/log# ls messages*
messages        messages.0.bz2  messages.1.bz2  messages.2.bz2  messages.3.bz2  messages.4.bz2

Thanks, that's what I needed!

I said yesterday that your logs were there in /var/log

You did, and the above gave me detailed information about what was where and which files I needed to check out.
