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

ZFS – some initial testing

I thought I’d run some simple tests, based on a tuning thread I found: # dd if=/dev/urandom of=./file1 bs=1m count=1024 1024+0 records in 1024+0 records out 1073741824 bytes transferred in 14.283206 secs (75175127 bytes/sec) And while the above was running: # zpool iostat 5 capacity operations bandwidth pool used avail read write read write ———- —– —– —– —– —– —– storage 1.25G 9.06T 0 3 95 402K storage 1.25G 9.06T 0 0

HAST – High Availability Storage

2 Comments / FreeBSD, Open Source, PostgreSQL / By / /

HAST has just been added to FreeBSD: HAST allows to transparently store data on two physically separated machines connected over the TCP/IP network. Those two machines together will be called a cluster and each machine is one cluster node. HAST works in Primary-Secondary (Master-Backup, Master-Slave) configuration, which means that only one of the cluster nodes can be active at any given time. Active node will be called Primary node. This is the node

Pentabarf – seeing the speakers

Leave a Comment / Bacula, BSDCan, Conferences, FreeBSD, FreshPorts, Mountain Bikes, Open Source, Pentabarf, PGCon, PostgreSQL / By /

Both BSDCan and PGCon use Pentabarf for accepting and reviewing proposals for talks. An issue raised in 2009 highlighted the ability to see the speaker name when review the list of submissions. It is a bit of very useful information. This year, I’ve found out that we can see that vital data. Provided the speaker role has been set to confirmed. I think Pentabarf design assumes that you have created a talk, and

SVN commits now available

Leave a Comment / FreeBSD, FreshPorts, Open Source / By /

The SVN commits are now available for viewing. At present, only the FreeBSD src tree is working through SVN. Therefore, the easiest way for you to see those commits is through the FreshSource interface. That link takes you to the SVN version. You will notice that the src commits are duplicated. This was not done intentionally. However, it is fortunate in it allows for easy fact checking. This error is possible only because

Database load times

Leave a Comment / FreeBSD, Open Source, PostgreSQL / By /

With all the databases I run, I need a daily sanity check. I download a copy of each database and do a test load on my system at home. Today I timed that process: $ time ~/bin/backup-supernews.sh … real 77m57.323s user 12m52.610s sys 0m56.136s There are 11 such databases. The dump files range in size from 5K (globals.sql) to 2.8G (freshports.sql). The script that does this is pretty simple, but has evolved over
