ZFS & gmirror & drive renumbering

2 Comments / FreeBSD, General, Open Source, ZFS / By / / , ,

I am impressed…. my gmirror array continued to work even after the drives were renamed from da20 and da24 to ada0 and ada1. This happened when I tried out the ahci(4) for my SATA drives. It’s the type of thing I’m striving for soon in my ZFS array. All this started when I wanted to find out about making my ZFS array more resilient. See http://docs.freebsd.org/cgi/getmsg.cgi?fetch=663685+0+current/freebsd-stable (which is the top level post of

A simple nested loop

Leave a Comment / FreshPorts, PostgreSQL / By / /

In a previous post, I wrote about a suspected LIMIT problem. It turns out that suspicion proved correct. The solution was to move to a nested query which limits the underlying data and then allows the outer query to grab all the associated fluff that surrounds it. Here is the fix to the original code: $ cvs di -ub commits_by_committer.php Index: commits_by_committer.php =================================================================== RCS file: /home/repositories/freshports-1/classes/commits_by_committer.php,v retrieving revision 1.3 diff -u -b -r1.3

How many FreshPorts accounts are enough?

4 Comments / FreeBSD, FreshPorts, Open Source / By /

I found this interesting. The usual FreshPorts logging indicated an unusual number of account creations in a short amount of time. So I went looking. I found one IP address had created 20 logins. freshports.org=# SELECT ip_address, freshports.org-# count(ip_address) freshports.org-# FROM users freshports.org-# GROUP BY ip_address freshports.org-# ORDER BY 2 DESC freshports.org-# LIMIT 2; ip_address | count —————+——- 0.0.0.0 | 1203 95.211.27.210 | 38 (2 rows) freshports.org=# Ignore that 0.0.0.0. That indicates a

Bacula – errors with 5.0.0 backup catalog

4 Comments / Bacula, FreeBSD, Open Source / By /

While creating the FreeBSD package for 5.0.0, I noticed a few new things to be aware of. With 5.0.0 comes a new backup catalog script. It parses the bacula-dir.conf file and extracts what it needs from that. This means you only need to specify the database connection information in one place and it is not passed to a script via the command line. If you see this error while running that script: 25-Jan

NRPE: Unable to read output

1 Comment / Nagios, Network monitoring, Open Source / By /

After rebooting kraken to take a photo, I found nagios was displaying an error for my smartmon checks: NRPE: Unable to read output. Running the command by hand on the nagios server, I found: $ /usr/local/libexec/nagios/check_nrpe2 -H kraken -c check_smartmon_ad24 NRPE: Unable to read output But from the remote server I got: # /usr/local/libexec/nagios/check_smartmon -d /dev/ad24 OK: device is functional and stable (temperature: 29) I restarted npre and the problem went away… not

smartmontools

2 Comments / Mountain Bikes, Open Source, The FreeBSD Diary / By /

The smartmontools package contains two utility programs (smartctl and smartd) to control and monitor storage systems using the Self-Monitoring, Analysis and Reporting Technology System (SMART) built into most modern ATA and SCSI harddisks. In many cases, these utilities will provide advanced warning of disk degradation and failure. (The above shamelessly taken from the supplied URL). I just installed it: cd /usr/ports/sysutils/smartmontools/ && make install clean Then I set up the configuration file, with
