RHBA-2010:0431 - Bug Fix Advisory

Topic

Updated device-mapper packages that fix various bugs are now available.

Description

The device-mapper packages provide a library required by logical volume
management utilities such as LVM2 and dmraid.

This update applies the following bug fixes:

• fixes the device deactivation function so that the function fails if the

device is open. This fixes a problem that occurred when a device remained active
but the symbolic link was unexpectedly removed. (BZ#583900)

• optimizes regular expression parsing for shared character prefixes. This

shortens processing of lvm2 filters with many devices with a shared prefix.
(BZ#584345)

All users of device-mapper should upgrade to these updated packages, which
resolve these issues and include these enhancements.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
