NOTE: the time stamp is as the start of the service, not at the end.
so, right here. LVM startup
16 secs for lvm startup is nothing. :-)
How many VG and LV you have ?
I have 32 lv's spread across 3 VG's and 5 GB spread across 3 PV's (one for
each VG).
It takes me between 2 to 3 minutes (about 150 to 180 secs) to do the lvm
initialization.
What I have found to help was to do the LV initialization as part of the
initial boot stage.
On my kernel boot line in grub.conf, I have the following:
rd.lvm.vg=INSTALLATION rd.lvm.vg=VM rd.lvm.vg=ClassRoom
rd.lvm.lv=INSTALLATION/F19
The rd.lvm.vg's are my multiple (3) VG's
The rd.lvm.lv is the /
There will STILL be a delay. In my case, the delay is about 3 minutes (as I
noted above). w/o the rd.lvm.vg it would take noticeably longer.
Hope that helps, your mileage may vary.
All the best,
