I’ve been using Nagios for a while. I use it to monitor many things, varying from disk space to disk temperature. One of the packages I use for this is net-mgmt/nagios-check_smartmon. This code is getting out of date it seems. According to the timestamp at the top of the file, the last time it was […]

After the zfs send, I had system/foo/bar, but I really just wanted system/bar. How do I fix that? mv(1) was my first guess. I was wrong. What I wanted was zfs(8) rename. Let me explain. After doing my: zfs send storage/compressed/bacula@2013.07.22:06:33 | mbuffer | ssh -t dan@10.5.0.20 ‘zfs receive system/usr/local/bacula/FromKraken’ I quite, correctly, wound up

Today it finished. That ZFS send I started on Monday finally finished. Recap The original command was: # zfs send storage/compressed/bacula@2013.07.22:06:33 | mbuffer | ssh -t dan@10.5.0.20 ‘zfs receive system/usr/local/bacula/FromKraken’ That’s was the initial send of the filesystem. But more data has been added to it. So I take another snapshot, and send that: Send

I keep getting this message in my email, daily, at midnight UTC: newsyslog: can’t notify daemon, pid 2090: No such process This is generated by this entry: $ grep hp http /etc/newsyslog.conf /var/log/httpd-*.log 640 28 * $D5 BG /var/run/httpd.pid 30 This rolls over the log files for me.

Earlier today, I started a zfs send | zfs receive between the old file server and the new file server. It won’t finish until early morning tomorrow. [root@kraken ~]# zfs send storage/compressed/bacula@2013.07.22:06:33 | mbuffer | ssh -t dan@10.5.0.20 ‘zfs receive system/usr/local/bacula/FromKraken’ Pseudo-terminal will not be allocated because stdin is not a terminal. in @ 54.9

Following up on last weeks comparison of 10 disks vs 8 disks on raidz2, it was suggested by Marie Helene that I try more HDD on the m/b. I’m here to report just that. I’ve put 5 HDD on the SUPERMICRO MBD-X8SIL-O Micro ATX Server m/b and five on the LSI SATA/SAS 9211-8i 6Gb/s. Here

Yesterday, I mentioned I wanted to compare raidz2 when using 10 disks versus using 8 disks. Along the way, I noticed that my ZFS-setup script needed a change to cope with mixed devices. Once I got past that hurdle, I started adding packages and setting up the system for some very simple tests. The test

THe last system I set up with ZFS, I used a script. Today, when trying a system with different device types, I encountered a limitation of that script. I need to fix it. In the above script, NUM takes on the value of what digits appear in the string of I. Given that DISKS contains

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
