Please help testing the new before-resync-target handler and the default implementation of it called snapshot-resync-target-lvm.sh . As the name implies this allowes one to take a snapshot of a volume just in the moment before it become target of a resynchronisation process. The obvious benefit of this is, that it in case your primary node dies during the resync, you still have an consistent albeit a bit outdated copy of your important data in the snapshot. While this might appear as a must have, it has to be pointed out that the LVM snapshot code might have bring considerable loss of performance to the resync speed. PS: Using a bigger chunksize of lvcreate (-c) was always beneficial in my test so far. The Changelog: 8.2.6rc1 (api:86/proto:86-88) -------- * The details of the LRU data structures is now hidden from /proc/drbd but can be re-enabled by echoing 1 to /sys/module/drbd/parameters/proc_details * Bash completion support for drbdadm (Installs on all distributions but RedHat, since they lack the /etc/bash_completion.d directory) * Fixed the out-of-sync handler it never fired. * Added the before-resync-target handler, and a default implementation of a handler that snapshots the target of a resynchronisation in case it is a LVM2 logic volume. * Improved error messages and documentation in regards to false positives of online verify and data-integrity-alg mechanisms in the presence of ReiserFS or the Linux swap code. * Merged all changes from 8.0.11 -> 8.0.12 into 8.2 http://git.drbd.org/?p=drbd-8.2.git;a=tag;h=drbd-8.2.6rc1 http://oss.linbit.com/drbd/8.2/drbd-8.2.6rc1.tar.gz -Phil -- : Dipl-Ing Philipp Reisner Tel +43-1-8178292-50 : : LINBIT Information Technologies GmbH Fax +43-1-8178292-82 : : Vivenotgasse 48, 1120 Vienna, Austria http://www.linbit.com :
