RHBA-2011:0718 - blktrace bug fix update

Synopsis

blktrace bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated blktrace packages that fix numerous bugs are now available.

Description

The blktrace packages contain a number of utilities to record the I/O trace information for the kernel to user space, and utilities to analyze and view the trace information. This includes: blktrace (to extract event traces from the kernel); blkparse (to produce formatted output of event streams); blkiomon (for i/o monitoring, periodically generating per-device request size and request latency statistics, and providing histograms); btreplay (for recreating IO loads recorded by blktrace); and btt (to analyze block i/o traces produces by blktrace).

These updated blktrace packages include numerous bug fixes. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.1 Technical Notes for information on the most significant of these changes:

https://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/6.1_Technical_Notes/index.html

All blktrace users are advised to upgrade to these updated packages, which addresses the bugs noted in the Technical Notes.
