When a device id is set for a device, using an idtype other than devname, it means that sysfs has been used with the device to match the device id. So, checking for a sysfs entry for the device in filter-sysfs is redundant. For any other cases not covered by this (e.g. devname ids), have filter-sysfs simply stat /sys/dev/block/major:minor to test if the device exists in sysfs. The extensive processing done by filter-sysfs init is removed. It was taking an immense amount of time with many devices, e.g. . 1024 PVs in 520 VGs . 520 concurrent vgchange -ay <vgname> commands . vgchange scans only PVs in the named VG (based on pvs_online files from a pending patch) A large number of the vgchange commands were taking over 1 min, and nearly half of that time was used by filter-sysfs init. With this patch, the vgchange commands take about half the time. |
