DESCRIPTION
dmeventd is the event monitoring daemon for device-mapper devices.
Library plugins can register and carry out actions triggered when
particular events occur.
LVM PLUGINS
-
Mirror
-
- Attempts to handle device failure automatically. See
lvm.conf(5).
-
Raid
-
- Attempts to handle device failure automatically. See
lvm.conf(5).
-
Snapshot
-
- Monitors how full a snapshot is becoming and emits a warning to
syslog when it exceeds 80% full.
The warning is repeated when 85%, 90% and 95% of the snapshot is filled.
See
lvm.conf(5).
Snapshot which runs out of space gets invalid and when it is mounted,
it gets umounted if possible.
-
Thin
-
- Monitors how full a thin pool data and metadata is becoming and emits
a warning to syslog when it exceeds 80% full.
The warning is repeated when 85%, 90% and 95% of the thin pool is filled.
See
lvm.conf(5).
If the thin-pool runs out of space, thin volumes are umounted if possible.
