Question FCoE drive only show changes on one host.


OK, so running into a bit of an odd issue with CentOS7 and 3PAR, I have created a volume on the 3PAR, exported it to my volume set and successfully mounted it in CentOS7 usinf xfs on two hosts as /storage, as it's going to hold the images for my VM cluster. However whenever I create a file or directory in /storage it does not appear on the other host, ie:
Host1
drwxr-xr-x 5 root root 4096 Apr 1 21:54 .
dr-xr-xr-x. 18 root root 4096 Apr 1 21:54 ..
drwxr-xr-x 2 root root 4096 Apr 1 21:54 temp
Host2
drwxr-xr-x 4 root root 4096 Apr 1 21:21 .
dr-xr-xr-x. 18 root root 4096 Apr 1 21:54 ..

Even if I create another directory/file on the 2nd host in an attempt to force it to update its view of the filesystem it won't pick up the temp directory, I suspect this is due to FS caching either on the 3PAR or the OS as if I reboot the system which presumably forces it to recheck the filesystem the dir will appear. Anybody had a similar problem or might be able to provide a hint on where I should be looking?

XFS is not a shared filesystem.
