lvmpolld

Start the daemon in the foreground

$ lvmpolld -f

$ lvmpolld -f -l debug

$ lvmpolld -t [300]

$ lvmpolld -s [/tmp/lvmpolld.socket]

$ lvmpolld -p [/tmp/lvmpolld.pid]

$ lvmpolld --dump

lvmpolld [options]

lvmpolld is the LVM poll daemon that supervises long-running LVM operations such as pvmove, lvconvert mirroring, and thin pool extension. It monitors these operations and updates their progress, allowing the initiating command to return while work continues in the background.
When an LVM command starts a polled operation, lvmpolld tracks its completion status. The daemon starts automatically when needed and shuts down after a configurable idle period.
The daemon communicates via a Unix socket, typically at /run/lvm/lvmpolld.socket, and maintains state about active operations.

-f, --foreground

Run in the foreground instead of daemonizing

Set log level (debug, info, warn, error)

Set idle shutdown timeout; daemon exits after being idle this long

Use a custom Unix socket path for communication

Use a custom PID file location

Dump the current state of the daemon and exit

Usually started automatically by LVM commands; manual invocation is rarely needed. If the daemon dies during an active operation, restarting the original command will resume polling. The --dump option is useful for debugging active operations.
