Moving from zroot from one zpool to another

Leave a Comment / beadm, Disks, FreeBSD, hardware / By /

Please also see Moving boot from one zpool to another and Adding a zroot pool to an existing system. On my 20x HDD system at home (also known as knew), I am having a recurring problem with booting. This is also the same system mentioned in my FreeBSD Forums thread about some CAM errors. Side note: I now think those CAM errors may be temperature related.  EDIT: 2018-12-29: They were not temperature related. […]

Running PHP on Nginx

Leave a Comment / nginx, Open Source / By /

I’ve been running Apache since 1998. Nginx didn’t exist then. FreshPorts runs on Apache mostly because that’s what I was using. There was no selection process. I use Nginx in a few locations, but I’ve never run FreshPorts on it. I am configuring a new server (x8dtu) for FreshPorts. So far, I have two jails: nginx01 pg01 My next task: get PHP running on nginx01. Name confusion While I was researching, I became

Bacula – ran out of space, moved some volumes to another zpool

Leave a Comment / Backups, Bacula, FreeBSD, ZFS / By /

I’m using Bacula 9.0.3 for this post, on FreeBSD 10.3 and 11.1. I did not document this as I went along, however, the details should be enough to get you started. NOTE: when I refer to the bacula-sd configuration, I mean the bacula-sd in question, not necessarily on the same server as bacula-dir. This will hopefully make you think carefully about which file you are modifying. NOTE: I am moving a whole Bacula

Bacula – copy to tape by job size

Leave a Comment / Backups, Bacula / By /

Backups are pretty amazing. The things you can do with them can be both highly entertaining and surprisingly easy. Today, we will venture into the easy part. Yesterday was the first Sunday of the month, which, according to my Bacula installation’s schedule is the day for full backups. Today, now that that is done, is copy-to-tape day according to my schedule. I do this manually because I don’t want the tape library, and

FreeBSD – what processes in what jails are using swap?

Leave a Comment / FreeBSD, Open Source / By /

Sometimes stuff gets swapped out. When it does, it’s good to know what is swapped. I was getting this Nagios alert this morning. I started searching. I found this post about showing what is using swap via: [dan@knew:~] $ ps ax | awk ‘NR==1{print};$3 ~ /W/’ PID TT STAT TIME COMMAND 12 – WL 54:27.37 [intr] 10147 – IWsJ 0:00.00 /bin/sh /usr/local/bin/mysqld_safe –defaults-extra-file=/usr/local/etc/mysql/my.cnf –based 12791 – IWsJ 0:00.00 /bin/sh /usr/local/bin/mysqld_safe –defaults-extra-file=/var/db/mysql/my.cnf –user=mysql –

Booting off the new 5TB drives

Leave a Comment / Disks, File Systems, FreeBSD, hardware, Open Source, ZFS / By /

This is about FreeBSD 11.1 on my knew server. I recently replaced the 3TB drives with 5TB drives. Along the way, it didn’t boot, the swap was adjusted, I got concerned about power, and there was a brief CAM status: SCSI Status Error scare. Then today, the planned reboot, I started asking questions on Reddit and on Twitter. The booting issue BIOS cannot boot from drives which present only 4096-byte sectors. This is

subversion via ssh passphrase-less key

Leave a Comment / Security, ssh, subversion / By /

In general, passphrase-less ssh keys are a security nightmare. It is similar to leaving the key to your front door in the lock. Anyone stumbling across it has access to your house. Similarly, if someone gets your ssh key, and there is no passphrase on it, they can use that key for anything which grants access to that key. Side note: How can you tell if a given ssh key has a passphrase?

After replacing 3TB drive with 5TB drive, FreeBSD 10.3 system did not reboot

1 Comment / Disks, FreeBSD, hardware, HBA, Open Source, ZFS / By /

I started replacing 3TB drives with 5TB drives in a 10 drive raidz3 array on a FreeBSD 10.3 box. I was not sure which drive tray to pull, so I powered off the server, and, one by one, pulled the drive tray, photographed it, and reinserted the drive tray. No changes were made. The first reboot Upon powering up, I was greeted by this (I have typed out the text for search purposes):

Logging, backups, and newsyslog.conf on FreeBSD

Leave a Comment / FreeBSD, syslog / By /

This morning, I was reviewing the logs and noticed these notices in /var/log/messages: I guessed that this was directly related to the zfs replace command I had issued the day before, but I wanted to confirm that. I like to use sudo instead of becoming root. One of the many benefits to this approach is logging. Everything is logged to /var/log/auth.log for later review. However, by the time I went to look, /var/log/auth.log
