Syslog Messages
1. LVM: VG 64 0x010000: Data in one or more logical volumes on PV 188 0x072000 was
lost when the disk was replaced. This occurred because the disk contained the only copy of
the data. Prior to using these logical volumes, restore the data from backup.
This warning is reported when LVM cannot synchronize the data on a replaced disk
automatically, and the data must instead be restored manually by the administrator
from a back-up. This warning typically occurs when LVM discovers an unmirrored
logical volume residing on the disk that was just replaced. When all the data on a
disk is mirrored on other disks and a copy is available, LVM will automatically
synchronize the data on the replaced disk from the mirror copies.
