Paragon CampTune – a handy tool to resize the Boot Camp partition

Recently I ran out of space on a Boot Camp partition with Windows 10 Pro. So I looked around for ways to make more space for Windows by shrinking the macOS partition and enlarging the Windows partition. Apple doesn’t officially support this in Boot Camp without reinstalling Windows, and doing these operations by hand, e.g. with the help of GNU Parted, is time consuming and tedious.

Luckily, I stumbled over Paragon CampTune, a commercial macOS utility (ready for 10.14 Mojave) that automates these tedious tasks and allows to resize the macOS and Boot Camp partitions on the fly, without having to reinstall Windows or macOS.

It finally worked wonderfully, the only irritating thing was that the tool showed a bland error at the first start of the repartitioning process: “Object not found”. After restarting the process with slightly different partition sizes, it could be successfully completed.

I can thus recommend this handy utility as it can save hours of work for a few bucks (ca. 22 USD).

Zimbra Collaboration Server: Troubles after updating to ZCS 7.1.1 – here’s the solution.

Generally, Zimbra‘s update scripts for ZCS run smoothly. However, after updating ZCS from 7.0.1 to 7.1.1 on Ubuntu 10.04.2 LTS a couple of days ago, I noticed that most of the server’s services crashed within 1-2 hours after starting the (virtual) server.

To make a long debugging story short, here’s a summary of the problem:

The update script doesn’t properly remove old entries in /etc/rsyslog.conf when creating a new dedicated rsyslog configuration file for zimbra (/etc/rsyslog.d/60-zimbra.conf). This makes rsyslog log its own logging due to double rule entries – making /var/log/zimbra-stats.log grow at 2 MB/s. Like this, zimbra effectively DOSes itself as the server runs out of free disk space in no time (my above-average 12 GB of free space were filled within about 1 hour 40 minutes).

And here’s the solution:

1. Stop rsyslog to stop it from filling up your disk with nonsense: ‘/etc/init.d/rsyslog stop’ or ‘service rsyslog stop’
2. If necessary (i.e. if the updated server has been running for several minutes already), reclaim your free disk space by deleting/emptying big log files in /var/log, e.g. zimbra-stats.log, zimbra.log, mail.info, mail.log, mail.err, mail.warn etc.
3. Edit /etc/rsyslog.conf and remove the entries (likely at the end of the file) that look similar to these:
local0.* @mail.yourserver.com
local1.* @mail.yourserver.com
auth.* @mail.yourserver.com
local0.* -/var/log/zimbra.log
local1.* -/var/log/zimbra-stats.log
auth.* -/var/log/zimbra.log
mail.* @mail.yourserver.com
mail.* -/var/log/zimbra.log
(these are now in /etc/rsyslog.d/60-zimbra.conf)
4. Restart rsyslog: ‘service rsyslog restart’
5. Restart ZCS if it doesn’t run properly anymore: /etc/init.d/zimbra restart (you may even have to reboot the whole box if that doesn’t work)
