[project-kimchi] [PATCH] logical pool fixes: only list leaf devices, and read file instead of run "cat"
by Zhou Zheng Sheng 19 Dec '13

19 Dec '13

Some devices are parent of other devices. We should just list the leaf devices but not parent devices. For example, if a disk contains partitions, we should only list the partitions. If a disk is held by multipath device, we should not list the disk. Currently we strip the last charactter from "vda1" to get "vda" and ignore the parent "vda" device. This may fails on disk contains lots of logical partitions, for example "vda10"'s parent is not "vda1". Another problem is this method can not find the parent-child relation ship between a multipath device and its slaves. The most accurate information is on sysfs, and lsblk lists all children device of the requested device based on sysfs. So when "lsblk -P devices" prints only one line, it's the device itself, when it prints more lines, they are the children devices. This patch use this method to detect if a device a leaf one. This patch also avoids start new "cat" process to read uevent file, it opens the uevent file and read it directly.

But it's not a reliable configuration. This rule will be lost after reboot. And shipping a configuration file is better than running commands in spec file. Please take a look at firewalld and firewalld.service http://manpages.ubuntu.com/manpages/raring/man5/firewalld.service.5.html It could be a better solution for the platforms where firewalld is available. -- project-kimchi mailing list <project-kimchi(a)googlegroups.com> https://groups.google.com/forum/#!forum/project-kimchi --- You received this message because you are subscribed to the Google Groups "project-kimchi" group.

This release adds many new features including: * Easy Template creation from Remote ISO images * Template customization * Basic guest customization * NSF and logical Pool support * Basic network management * Basic host management * Support for Kimchi plugins We have worked hard to ensure that Kimchi runs well on the most popular Linux distributions including: Fedora 19, Ubuntu 13.10, openSUSE 13.1, and RHEL 6.5. Kimchi uses standard Linux interfaces so it should run well on many other distributions too.
