Doc Text:
Previously, a bug has been introduced in lvm2-2.02.166-1.el7 (Red Hat Enterprise Linux 7.3 GA), that caused library incompatibilities with previous versions of Red Hat Enterprise Linux 7. That incompatibility could cause device monitoring to fail and be lost during an upgrade. The result was, that logical volumes that require monitoring would not have it, which could ultimately result in device failures going unnoticed (RAID) or out-of-space conditions not being handled (thin-p). A fix has been applied that addresses the incompatible issues and allows logical volume monitoring to continue as expected. It is possible to check the whether logical volumes are being properly monitored by specifying the 'segmonitor' field to 'lvs'. # lvs -o name,attr,segtype,segmonitor vg LV Attr Type Monitor my_linear -wi-a----- linear my_raid1 rwi-a-r--- raid1 not monitored Logical volumes which need no monitoring will not list a monitor state. Logical volumes which should have monitoring will list either 'not monitored' or 'monitored'. Monitoring can be turned on at any time by issuing an 'lvchange': # lvchange --monitor y <VG>/<LV>
