SnapDrive process failure in Linux -- more

[GLENYU5820]

The 'SnapDrive process failure in Linux" was closed to add more comments. I had same issue with SDU v5.3.1 and after tried "export LVM_SUPPRESS_FD_WARNINGS=1" under /etc/profile. it did not help me. Later I found the issue from /etc/multipath.conf, after fixing it. The SDU works fine. Just want to share this out.
