3par FC connected cluster issues

When adding a volume to to our proxmox ccluster 5.1.41 we have encountered this error


The lvm.conf is as follows:

# Do not scan ZFS zvols (to avoid problems on ZFS zvols snapshots)
global_filter = [ "r|/dev/zd.*|", "r|/dev/mapper/pve-.*|" ]
#global_filter = [ "a|/dev/mapper/mpath.*|", "r|/dev/.*|", "a|/dev/mapper/pve-.*|" ]
# Example
We also set the lvmetad = 1

The multipath.conf is :
defaults {
polling_interval 10
user_friendly_names no
find_multipaths yes
}
devices {
device {
vendor "3PARdata"
product "VV"
path_grouping_policy multibus

}
}

We continue to get the errors listed above and cannot seem to fix this. It is almost like the
multipath_component_detection is not working. Has anyone seen this issue?


Best regards
