The traditional thoughts on ZFS are to have arrays which are a power-of-2 when it comes to number of disks. That means 2, 4, 8, etc. But for raidz1, that would be 3, 5, 9. For my choice of raidz2, it would be 4, 6, and 10. In the system I’m building up now, I […]

My gateway is dying. My file server is getting full. Over the past few weeks, I’ve been dealing with aging infrastructure. My development server started acting up and was showing signs of age. This aging desktop box contained 80GB HDD, which means it’s probably 6 or 7 years old. That’s getting on in age. It’s

I was trying to recompile sysutils/bacula-client on a FreeBSD 8.4 jail when I encountered some perplexing link errors. It took me a while to figure it out, but with the help of some IRC conversation, we figured it out. I started off by deleting the old (quite old) port: bacula-client-5.0.3 Then I recompiled: cd /usr/ports/sysutils/bacula-client

I recently upgraded a jail server from FreeBSD 8.2 to FreeBSD 8.4. This stopped various jails from starting their own instances of PostgreSQL. The messages in the logs were: Jul 9 14:48:48 building postgres[40785]: [2-1] FATAL: could not create shared memory segment: Function not implemented Jul 9 14:48:48 building postgres[40785]: [2-2] DETAIL: Failed system call

I recently upgraded a jail server from FreeBSD 8.2 to 8.4, and part of that process involved recompiling all of the applications. Along the way, nrpe on one jail stopped working. Nagios was reporting: CHECK_NRPE: Socket timeout after 10 seconds. Trying from the command line gave: $ /usr/local/libexec/nagios/check_nrpe2 -H -H dbclone.example.org -c check_pgsql -t 1

The other day, I disconnected the ethernet cable from my gateway to reroute the cable. Then, perhaps coincidentally, I started seeing these entries: Jul 2 15:19:57 bast kernel: fxp0: discard frame w/o leading ethernet header (len 4294967294 pkt len 4294967294) Jul 2 15:28:01 bast kernel: fxp0: discard frame w/o leading ethernet header (len 4294967294 pkt

After upgrading subversion on my svn server, I started seeing this errors from viewvc: An Exception Has Occurred Python Traceback Traceback (most recent call last): File “/usr/local/viewvc/lib/viewvc.py”, line 4827, in main request.run_viewvc() File “/usr/local/viewvc/lib/viewvc.py”, line 251, in run_viewvc self.rootpath = vclib.svn.canonicalize_rootpath(rootpath) File “/usr/local/viewvc/lib/vclib/svn/__init__.py”, line 39, in canonicalize_rootpath rootpath = _canonicalize_path(rootpath) File “/usr/local/viewvc/lib/vclib/svn/__init__.py”, line 23, in

I’ve been a fan of PostgreSQL since 2000 when I switched to it from MySQL. I wanted stored procedures and functions. I got that with PostgreSQL. I was used to having such features from my years working with other big databases such as DB2, Oracle, and Sybase. I’ve been moving towards using the custom format

I started seeing this error: Jun 10 19:12:38 nyi sshd[92208]: error: key_read: uudecode AAAAB3NzaC1yc2EAAAABJQAAAIBdX/USEtxnO91Vpujney8gwkq2sRrcU9R6nKAoGv1eNMWrMD9a93kZMjR4fFMAH87g+zyHBftxCsyE0wJX2A0UFgIQsiuOOINkTJMyk\n failed I couldn’t figure it out. Then I searched ~/.ssh/authorized_keys for that string. I found it in there. But the line was incomplete. It looked like I’d deleted the last part of the line. It should end with something like this:
