This post has been replaced by a newer post. This is the previous post for this system configuration. For future reference, this is the knew server … oh wait, I think it’s this server which is was mounted in the 3U chassis mentioned in this post (perviously erroneously referred to as a 4U). It runs a few jails, including Bacula regression testing services. It is now mounted in a SuperChassis 846E16-R1200B This recent […]
This server, knew has had an intermittent problem related to CAM status: SCSI Status Error messages. There is a FreeBSD Forums post about it. On Sunday, the problem returned, and this time it degraded the zpool. I collected the information in this gist and I will list the relevant portions below. I had enabled smartd testing and I received this email late on Sunday: Despite the promise of more information in the logs,

NOTE: I am not convinced of the value of doing these tests on a regular basis. smartd and smartctl are two utility programs included with the smartmontools package. On FreeBSD, smartmontools is installed via the sysutils/smartmontools port. Those programs can “control and monitor storage systems using the Self-Monitoring, Analysis and Reporting Technology System (SMART) built into most modern ATA/SATA, SCSI/SAS and NVMe disks. In many cases, these utilities will provide advanced warning of

This is a work in progress. As I make more decisions and receive additional suggestions/advice, I will update this page. I live in an apartment. The Verizon FiOS ONT is outside on the ground floor. I live two floors up. I am considering moving the rack from the bedroom to 7x12ft locked room in the basement. It would share space with my washer and dryer (which is vented to the outside). Why? noise

World, please meet tape02. It’s been around for a while, but never properly introduced. For the record:
My Unifi US-16-XG switch was offline. It was still functioning correctly, but it was not in contact with the Controller. I wasn’t sure how to fix this, but this blog post shows what I now think should always work. It consists of two steps: Get the switch talking to the Controller Make the above change permanent The key point to remember: the Controller is always the voice of authority when it comes to

I have two Unifi WAPs at home. I’ve installed them at three other locations. They are a great product. One problem I had was getting the management interface set. By that, I mean the IP address of the unit. I wanted it to be in a specific range, and therefore it had to be in a specific VLAN. However, I wanted the WIFI traffic to be in a different VLAN. It is not

I’m writing this down so I can find it later. The management IP address on my Unifi US-16-XG is wrong. I’m going to change it via a combination of the controller and the CLI. Let’s hope this works. Hope? Why hope? Unifi switches are designed to be managed via the webgui (i.e. their controller). I’m sure this will also work on my US-48 switch too. Get connected and get in I’ve done this

I’ve been given a Dell PowerEdge 710. I’ve installed two 30GB SSDs, installed FreeBSD 11 on them, and added four 500 GB SSDs. It will become a tape library server, replacing the R610 which will no longer be used. Some of the hardware came from the R610. The zpools: The filesystems: And dmesg:
