RHBA-2015:2147 - Bug Fix Advisory

Topic

Updated lvm2 packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 7.

Description

The lvm2 packages include complete support for handling read and write operations on physical volumes, creating volume groups from one or more physical volumes, and creating one or more logical volumes in volume groups.

This update fixes the following bugs:

• Previously, the dm-event.socket and lvm2-lvmetad.socket systemd units incorrectly referenced the "RemoveOnStop" property, which was not available in the previous version of systemd. As a consequence, the "Unknown lvalue 'RemoveOnStop' in section 'Socket'" error occurred at boot time or when systemd reloaded its units. With this update, "RemoveOnStop" is recognized, so the dm-event.socket and lvm2-lvmetad.socket can reference this property, and the error message no longer occurs. (BZ#1200946)
• In an earlier version, LVM2 introduced support for write caching mode, which is stored in metadata. Consequently, metadata without caching mode was considered invalid and the system could become unbootable. With this update, metadata without set cache mode uses the default caching mode write-through. As a result, logical volumes with older metadata can be activated as expected. (BZ#1207714)

Also, this update fixes bugs in the following areas:

• thin provisioning (BZ#1163530, BZ#1166873)
• cache (BZ#1269677, BZ#1269677, BZ#1167431, BZ#1243982, BZ#1247378, BZ#1255184)
• raid (BZ#1186903, BZ#1067112, BZ#1194464)
• lvm2app library (BZ#1211183, BZ#1139920)
• PV handling (BZ#1185438, BZ#1106425)
• lvmetad (BZ#1106425)
• clvmd (BZ#1081940, BZ#1140095)
• blkdeactivate script (BZ#1201733, BZ#1209855)
• documentation (BZ#1038524, BZ#1193925)

In addition, this update adds the following enhancement:

• LVM volume groups can now be assigned an owner. The volume group owner is the system ID of a host. Only the host with the given system ID can use the VG. This can benefit volume groups that exist on shared devices, visible to multiple hosts, which are otherwise not protected from concurrent use from multiple hosts. LVM volume groups on shared devices with an assigned system ID are owned by one host and protected from other hosts. (BZ#1246231)

Also, this update adds enhancements in the following areas:

• LVM reporting, processing, and selection (BZ#1240518, BZ#1085684, BZ#1240538)
• thin provisioning (BZ#1153362, BZ#1189215, BZ#1189051)
• cache (BZ#1229756)
• IO reporting (BZ#1222101)
• polldaemon (BZ#1044705)
• lvmconf script (BZ#1211507)

Users of lvm2 are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
