In fact there may even be a bug in here, though I think I've brought up the fact that lvm will activate in single machine mode the same volume on multiple nodes. [root@taft-01 ~]# vgchange -aye taft 2 logical volume(s) in volume group "taft" now active [root@taft-01 ~]# lvs LV VG Attr LSize Origin Snap% Move Log Copy% Convert LogVol00 VolGroup00 -wi-ao 58.38G LogVol01 VolGroup00 -wi-ao 9.75G clinear taft owi-a- 100.00M lvol0 taft swi-a- 12.00M clinear 0.07 # here the snap doesn't get activated, but the origin does. [root@taft-02 ~]# vgchange -aye taft _get_device_info: device not found 1 logical volume(s) in volume group "taft" now active [root@taft-02 ~]# lvs -a -o +devices LV VG Attr LSize Origin Snap% Move Log Copy% Convert Devices LogVol00 VolGroup00 -wi-ao 58.38G /dev/sda2(0) LogVol01 VolGroup00 -wi-ao 9.75G /dev/sda2(1868) clinear taft owi-a- 100.00M /dev/sdb1(0) lvol0 taft swi--- 12.00M clinear /dev/sdc1(0) bug 677739 should block this feature. Marking this FailsQA until the fix for 677739 is included. 6777739 now in POST (upstream in version 2.02.85), marking this one POST as well. 677739 has now been verified. Marking this feature verified as well with the latest rpms. 2.6.32-94.el6.x86_64 lvm2-2.02.83-3.el6 BUILT: Fri Mar 18 09:31:10 CDT 2011 lvm2-libs-2.02.83-3.el6 BUILT: Fri Mar 18 09:31:10 CDT 2011 lvm2-cluster-2.02.83-3.el6 BUILT: Fri Mar 18 09:31:10 CDT 2011 udev-147-2.31.el6 BUILT: Wed Jan 26 05:39:15 CST 2011 device-mapper-1.02.62-3.el6 BUILT: Fri Mar 18 09:31:10 CDT 2011 device-mapper-libs-1.02.62-3.el6 BUILT: Fri Mar 18 09:31:10 CDT 2011 device-mapper-event-1.02.62-3.el6 BUILT: Fri Mar 18 09:31:10 CDT 2011 device-mapper-event-libs-1.02.62-3.el6 BUILT: Fri Mar 18 09:31:10 CDT 2011 cmirror-2.02.83-3.el6 BUILT: Fri Mar 18 09:31:10 CDT 2011 Just a note that bug 694164 (targets not resumed when creating multiple snapshots of mirrors) may be seen when attempting this feature. This may require a note in the docs. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
