Booting off the new 5TB drives
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

Replaced a drive? What about that gmirror swap?
I just swapped out a drive which was involved in a gmirror swap. This is the current status: $ gmirror status Name Status Components mirror/swap DEGRADED da0p2 (ACTIVE) da2p2 (ACTIVE) da3p2 (ACTIVE) da4p2 (ACTIVE) da5p2 (ACTIVE) da9p2 (ACTIVE) da10p2 (ACTIVE) Here is how I can fix that: sudo gmirror forget swap The above tells gmirror to forget about components which are not connected. As you can see here, it makes gmirror happy. $

subversion via ssh passphrase-less key
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
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
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

Swapping 5TB in, 3TB out
In this power, the server is running FreeBSD 10.3. I am completely and unreasonably biased: ZFS is the best filesystem out there. Do not take my word for it. Ask around. Today, I started a process I’ve been waiting to do for a while. I am replacing the 3TB drives in a 10-drive raidz2 array with 5TB drives. These new drives are faster, I think perhaps cooler, and, more to the point, bigger.
