Administrator. James is right. I just did it and works. The drive where you are going to record the image has to be formatted with mac system. HFS.

The disk has to have enough space. Check it.
Has to be formatted for MAC System.
I Disk Utility you click Erase> click The HDD the you want to format. Choose the system. End click erase.

Comment on Startled by “component device mismatches” on RAID1 volumes by Alex

In my case mismatches had exactly the value of 128 and appeared only for /boot partitions on raid1. I think this pretty normal, because event sequence was as follows:
1) OS installed on 2 HDDs with /boot and / partitions on RAID1 via mdadm
2) /dev/sdb at some point became faulty and was replaced
3) sfdisk -d /dev/sda | sfdisk /dev/sdb
4) mdadm /dev/md0 –add /dev/sdb1
5) echo -e “root (hd1,0)\nsetup (hd1)\nquit” | grub –batch

At stage 5) grub writes directly to HDD, omitting the raid1 level, so /dev/sda1 and /dev/sdb1 become out of sync and weekly cron job 99-raid-check complains about mismatches.

Comment on DPD-Paketdienst-Zumutung: Zustellung an falsche Person by Karl R.

Hallo, geht mir auch so, DPD hat gestern laut Tracking-ID ein Paket an mich ausgeliefert, welches jedoch nie bei mir ankam. Als Emfpänger wurde ein Herr oder Frau “M-” angegeben, bei uns in der Nachbarschaft gibt es jedoch keinen Herrn oder Frau M.
Ich muss heute DPD anrufen. Wenn das Paket bis morgen nicht da ist, gibt’s Ärger!

Ich hoffe, der Fahrer bzw. DPD wird Konsequenzen ziehen.

Comment on Monitor number of active connections to MySQL using Nagios by Administrator

@Andy: You need nagios-plugins-basic installed (this is how the package is named in Debian, it should give you an idea what to install for other distros).

It happened that I saw this error (again) a couple of days ago. Since it startled me again I googled for it — and came across my own above article as the first hit. I had simply forgotten that I had seen and investigated this error already a while ago…

I had to remove a “;” in the perfdata output to make it work with pnp-0.4:
my $perfdata = "mysql_connections=$threads_connected;$warn_threshold;$critical_threshold;0;0";
