Description Rodrigo A B Freire 2016-08-30 20:30:33 UTC
Description of problem:
multipath-based LVM is not activated at system startup, thus causing

Version-Release number of selected component (if applicable):
device-mapper-1.02.107-5.el7_2.1.x86_64

How reproducible:
Intermitent; always in some select systems

Steps to Reproduce:
1. Present 4 1-TB LUN to the system
2. Set the volumes as a 4 TB VG / LV
3. Configure it to mount at startup in 

Actual results:
System should activate the VGs upon boot time

Expected results:
VGs are not activate and boot fails because of missing LV.

Additional info:
This issue is mitigated by disabling lvmetad (lvmetad = 0 in /etc/lvm/lvm.conf)

If possible, please follow instructions to collect more debug info as already described in bug #1324028 comment #10 and attach it here.

Also, would it be possible for the customer(s) to try the latest 7.2.z lvm2/device-mapper (lvm2-2.02.130-5.el7_2.5) and device-mapper-multipath (device-mapper-multipath-0.4.9-85.el7_2.6) packages and check if they can still reproduce - we've fixed a few issues there which may be related.

I've yum updated my servers and seems like the issue I was having before is gone. The lvm version is now 7:2.02.130-5.el7_2.5 and multipath is 0.4.9-85.el7_2.6

OK, those packages contain several important fixes in the area of device caching in LVM2 and also in the area of LVM2 and multipath cooperation.

I'm closing this bug report now. If you run into this issue again, please, reopen this report. Thanks.
