I found out that the issue was indeed the RAID controllers in the R610.  The particular version of the PERC 6 was not compatible with the Ubuntu Kernel and was this not handling the SSDs properly.  After replacing them with the PERC 6/i with the battery backup, everything survived an entire weekend shut down.  Thanks everyone for the suggestions and help.
Hello everyone!  I have been working on an ongoing issue with some refurbished Dell R610 servers with the SAS6IR controller ruhnning a pair of Kingston 256GB SSDs in RAID1 configuration.  I have 5 of these servers and all are identical and all have the same issue which is why I am leaning--at the point anyway--to more of a settings issue rather than hardware since I have swapped the SSDs around among servers as well as tested them in an R710 and the issue arises in all R610s but the 710 using the same drives does not exhibit the issue.  So, on to the actual issue: file system corruption after being shutdown and powered off by the OS--not power failure or power button.  I have tried using Ubuntu Linux, RHEL7, Windows Server 2k8 and have seen the issue in the Linux O/Ss but not Windows--even XenServer worked flawlessly after a 4 day weekend shutdown, which lends me to think it is Linux related.  Everything shows up fine in Main and 6IR bios as far as all drives/RAID volumes and running diagnostics on the drives shows they are all in good health.  I can install and reboot until the cows come home and there is no issue.  But when I shutdown the system completely (this is a test lab environment and not yet in in production environment) using the shutdown option in the OS and gracefully shut down the system and power off, but not unplug from the power outlet/UPS when I power back on--usually after being shut down overnight, but also does the same after an hour or so as well--Everything POSTs fine and starts the boot sequence.  The RAID array and Volume is found and the OS starts booting.  It is then that the system will either come to a command prompt instead of the GUI or will halt with a file system corruption error saying there are deleted inodes.  I am in the process of downloading the Dell Diagnostic DVD and will see what it comes up with, but this issue has been frustrating me for almost 2 months now as I struggle to find what the cause is.  Any further info needed, please let me know.  Thank you in advance. Scott
