This post is deprecated by this one. After a failed first attempt to get the SAS card working with a tape library, John Baldwin suggested I try mfip (there is no man page for it), but I discovered it was a kernel module. I issued the kdload mfip command, checked /var/log/messages, and found the tape library and drives had been added: Jan 1 00:30:42 tape01 kernel: mfip0: on mfi0 Jan 1 00:30:42 tape01 […]
When I couldn’t see any tape library associated with my SAS card, I decided to play with mifutil in case that provides any useful information. # mfiutil -u 0 show adapter mfi0 Adapter: Product Name: PERC 6/E Adapter Serial Number: 1122334455667788 Firmware: 6.2.0-0013 RAID Levels: JBOD, RAID0, RAID1, RAID5, RAID6, RAID10, RAID50 Battery Backup: not present NVRAM: 32K Onboard Memory: 256M Minimum Stripe: 8K Maximum Stripe: 1M # mfiutil -u 0 show firmware

This post is deprecated by this one. World, please meet tape01, the newest addition to my home lab, and reincarnated from an old server. These are the screen shots of the Dell PERC 6E card BIOS configuration. But for the record:
Yesterday and today, none of my Bacula copy-to-tape jobs completed because my tape drive was missing. Today, I reseated all the cables, and power cycled the tape library. In my ssh session, I did this: $ sudo camcontrol devlist <ATA TOSHIBA DT01ACA3 ABB0> at scbus0 target 2 lun 0 (da0,pass0) <ATA TOSHIBA DT01ACA3 ABB0> at scbus0 target 10 lun 0 (da1,pass1) <ATA TOSHIBA DT01ACA3 ABB0> at scbus0 target 11 lun 0 (da2,pass2) <ATA

This is tape01, the server to which the DELL TL4000 will be attached. At one time, it was my gateway/firewall/router. Of interest is the SAS card. You can see photos here. $ grep mfi /var/log/messages Dec 30 14:48:02 tape01 kernel: mfi0: <Dell PERC 6> port 0xd000-0xd0ff mem 0xfbec0000-0xfbefffff,0xfbe80000-0xfbebffff irq 19 at device 0.0 on pci3 Dec 30 14:48:02 tape01 kernel: mfi0: Using MSI Dec 30 14:48:02 tape01 kernel: mfi0: Megaraid SAS driver Ver

I encounter edge cases. It’s not fun. This particular situation caused OXS Mail.app to crash when using a VPN.

NOTE: If you are looking to configure net-mgmt/net-snmp for the first time, the latest article is Configuration of net-mgmt/net-snmp on FreeBSD. NOTE: IF YOU WANT TO GET IT WORKING, skip down to The Recipe. See also net-mgmt/net-snmpd wants /snmp/snmpd.conf for later versions of net-snmpd. I want to measure more stuff.

Yes, this was not fun. I took some notes, but not everything. Please read the notes if you plan on doing these foolish things. I was cleaning up /usr/src on a host which does not hold src. I looked and found: It was there that I knew I’d done the wrong thing. Trying snapshots Let’s look for snapshots, find one from a few minutes ago, and rollback to that. $ zfs list -t

I’m using FreeBSD 10.2-RC2 here, with a bunch of HDD. Here are the current pools: The degraded music pool contains a drive I will be replacing later in this post. But first, I want to replace a mis-matched drive in the benchmarking pool. I noticed that when I saw this output: The serial number on line 19 is of a different format. I suspected I was using different size drives because I knew

I wasted a few hours today trying to figure out why special characters in passwords were causing problems. I was chasing the wrong problem. Conclusion: smart quotes are dumb. Full disclosure: I should have seen the problem. The problem is not with LibreNMS. Here is my procedure for creating an snmp read-only
