Hello
I found my mail which sent on last Friday and yesterday didn't appear in
mail list, it may be blocked for attachment. So I resend it without
attachment.
---below is original mail--
Hello David,
When event_activation=1 & obtain_device_list_from_udev = 0 in lvm.conf.
the boot time became: 1min 9.349s (before time: 2min 3.661s)
When event_activation=0 & obtain_device_list_from_udev = 0
time: 1min 7.219s (before time: 1min 57.478s)
And the systemctl status for pvscan when time is 2min & 1min (obtain_xx=0)
```
# ls -lh *.txt
-rw-r--r--. 1 root root 640K Aug 30 19:17
systemctl-status-all-pvscan-1min.txt
-rw-r--r--. 1 root root 664K Aug 30 18:49
systemctl-status-all-pvscan-2min.txt
```
the scripts:
```
for i in `systemctl list-units | grep lvm2-pvscan | cut -d' ' -f 3`; do
systemctl status $i; done > systemctl-status-all-pvscan-2min.txt
```
There are 2 test result for above for loop. (these files will delete 3
months later)
1> systemctl-status-all-pvscan-1min.txt
event_activation=1 & obtain_device_list_from_udev = 0
2> systemctl-status-all-pvscan-2min.txt
event_activation=1 & obtain_device_list_from_udev = 1
Test result URL:

Thanks.
