In cPanel 11.25 we have made a few feature improvements to the bandwidth tracking system built into WHM and cPanel. While these new features grants you a much more accurate and granular view of client bandwidth usage, customers with inadequately sized /var partitions may run into issues related to partition size and disk space consumption.
It should also be noted that the creation of these files occurs during the first upcp that results in an upgrade to 11.25 and can require significantly more time than normal upgrades.
The notice for this change was in our release notes for 11.25 which can be found at http://docs.cpanel.net/twiki/pub/AllDocumentation/ReleaseNotes/1125releasenotes.pdf
Change: Bandwidth graph RRD files are split off for each individual service per domain and subdomain and stored in /var/cpanel/bandwidth/ .
Potential Issue: On some machines, depending on the partitioning schema and the number of domains on a server, there may be a disk space issue. This will only effect customers with large numbers of domains and a relatively small /var/ partition, i.e., 8-10G. In these situations, the /var/ partition may become full.
Workaround: For the time being, if you are affected by this issue, we are suggesting the following temporary fixes.
- Disabling Bandwidth Stats Generation: ‘touch /etc/rrdtooldisable ’ . This will disable generation of the rrdfiles altogether. Removing this file will result in the graphs being generated again.
or
- Symlinking /var/cpanel/bandwidth to a partition with more space.
mkdir /home/bwtmp; tar -czvf /root/cp-bandwidth-backup.tar.gz /var/cpanel/bandwidth
mv /var/cpanel/bandwidth/* /home/bwtmp/; rm -rf /var/cpanel/bandwidth
ln -s /home/bwtmp /var/cpanel/bandwidth
The above command will create a /home/bwtemp directory, copy the contents of /var/cpanel/bandwidth to it, create a backup in /root/cp-bandwidth-backup.tar.gz, and then symlink the old directory to the new one where there should be more diskspace.
If you have issues executing the fix for this change, please submit a ticket via https://tickets.cpanel.net and we will assist you with this fix.
- EDGE - The latest build, with the newest features and least testing. We do not recommend running this build on a production web server.
- CURRENT - More mature and tested than EDGE.
- RELEASE - The preferred build for a production server, as it is generally current enough to contain the latest fixes and new features.
- STABLE - For conservative web hosts who do not wish to run the latest release.
Exciting news! We just published the latest version of our Linux web hosting software — cPanel/WHM 11.25 — to the EDGE build.*
While cPanel/WHM was already famous for its ease of use and reliability, version 11.25 offers several improvments, including:
Usability enhancements
- Quicker access from mobile devices, due to fewer authentication requests from the server.
- IMAP IDLE support for mobile devices, allowing near real-time mail delivery from Dovecot mail servers.
- Streamlined cPanel interfaces, such as Email Accounts and MX Entry.
- An overhauled language system that provides greater accuracy and language compatibility, with less memory consumption.
Security features
- Session tokens and blank referer checks, to help prevent cross-site request forgery.
- Better cPHulk reliability, for improved protection against brute force attacks.
Efficiency improvements
- Lower memory consumption during synchronization of DNS clusters.
- Quicker restart processes for both the Apache web server and the BIND nameserver.
- Quicker load times for the cPanel home page.
More info on efficiency improvements.
And those are just a few of the upgrades you get with 11.25! For more detailed information, take a look at our cPanel/WHM 11.25 website.
For technical details, see our version 11.25 release notes.
Note: As of version 11.25, cPanel will discontinue support for the x and x2 themes. During installation of 11.25, current users of the x and x2 themes will automatically be switched to the up-to-date x3 theme, which uses the x branding package.
The cPanel forums (http://forums.cpanel.net) have been upgraded to make them mobile compatible. The new upgrade provides a scalable WML, WCSS style that bridges the gap between mobile devices and the forum software.
WCSS (WAP Cascading Style Sheet or WAP CSS) is the mobile version of cascading style sheet. It is a subset of CSS2 (the cascading style sheet language of the World Wide Web) plus some WAP specific extensions. CSS2 features and properties that are not useful for mobile Internet applications are not included in WAP CSS. WAP CSS is the companion of XHTML Mobile Profile (XHTML MP). Both of them are defined in the WAP 2.0 specification, which was created by the former WAP Forum (now the Open Mobile Alliance).
To access the mobile version of the forums you can visit http://wif.cpanel.net on your mobile device.
Today cPanel has released a new DNS Only product which is based on the core of cPanel/WHM 11.24.4. This updated version adds support for cPanel's Service Manager, enhanced service monitoring, brute force protection, as well as many of the other new features and optimizations found in cPanel/WHM 11.24.4.
cPanel strongly recommends upgrading to this new version as soon as possible. Anyone who has a significant number of DNS updates each day will find improved performance and scalability with DNS Only version 11.24.4.
