Port another optimization from pvscan -aay to vgchange -aay: "pvscan: only add device args to dev cache" This optimization avoids doing a full dev_cache_scan, and instead populates dev-cache with only the devices in the VG being activated. This involves shifting the use of pvs_online files from the hints interface up to the higher level label_scan interface. This specialized label_scan is structured around creating a list of devices from the pvs_online files. Previously, a list of all devices was created first, and then reduced based on the pvs_online files. The initial step of listing all devices was slow when thousands of devices are present on the system. This optimization extends the previous optimization that used pvs_online files to limit the devices that were actually scanned (i.e. reading to identify the device): "vgchange -aay: optimize device scan using pvs_online files" |
