RHBA-2009:1476 - lvm2 bug-fix update

Synopsis

lvm2 bug-fix update

Type/Severity

Bug Fix Advisory

Topic

Updated lvm2 packages that fix bugs are now available.

Description

The lvm2 packages contain support for Logical Volume Management (LVM).

This update applies the following bug fixes:

  • Adds new option prioritise_write_locks in lvm.conf. Without enabling this option, whenever there are competing read-only and read-write access requests for a volume group's metadata, the write access may be stalled by a high volume of read-only requests.

    NOTE: This option only affects locking_type 1 (local file-based locking).

  • Make all tools use consistent lock ordering. This fixes vgextend command to block instead of failing when requested Volume Group is locked read-only.

  • Use read-only instead or write lock for lvchange --refresh.

  • Adds global/wait_for_locks to lvm.conf so blocking for locks can be disabled.

  • Fixes bug where non-blocking file locks could be granted in error.

All users of lvm2 are advised to upgrade to these updated packages, which resolve these issues.

Solution

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