TopoLVM

TopoLVM is a Commodore component to manage topolvm.

See the parameters reference for further details.

Setup

  • Create an LVM VolumeGroup named vgssd on the nodes you want.

  • Add a label syn.tools/topolvm="" to the nodes which have the VolumeGroup.

Maintenance

Extending Capacity

TopoLVM (lvmd) scans all nodes every 10 minutes, so to extend the capacity of a node just extend its volume group and wait until the capacity change is picked up by TopoLVM.
