Description Marius Vollmer 2015-08-18 12:57:26 UTC 
Description of problem:

Starting multipathd will correctly set up device mapper for the existing multipath devices, but the ID_FS_TYPE udev property of newly enslaved block devices are not updated.  They are updated only after an explicit "udevadm trigger". 

Version-Release number of selected component (if applicable):
device-mapper-multipath-0.4.9-73.fc22.x86_64

How reproducible:
Always

Steps to Reproduce:
0. Setup multipath scenario with /dev/sdb and /dev/sdc
1. mpathconf --disable
2. reboot
3. mpathconf --enable
4. systemctl restart multipathd
5. multipathd list paths
5. udevadm info /dev/sda | grep ID_FS_TYPE

Actual results:
# multipathd list paths
hcil    dev dev_t pri dm_st  chk_st dev_st  next_check      
0:0:0:0 sda 8:0   1   undef  ready  running orphan          
2:0:0:0 sdb 8:16  1   active ready  running XXXXXXXXX. 19/20
2:0:1:0 sdc 8:32  1   active ready  running XXXXXXXXX. 19/20
# udevadm info /dev/sdb | grep ID_FS_TYPE
<empty>

Expected results:
# udevadm info /dev/sdb | grep ID_FS_TYPE
E: ID_FS_TYPE=mpath_member
