After following the directions by @Polanskiman for Tutorial: Install/Migrate DSM 5.2 to 6.1.x (Jun's loader) Jun1.02b I was able to successfully migrate to 6.1.4-15217. I downloaded the .pat files for UPDATE-2 through UPDATE-5 and used the GUI to manually upgrade. When I upgraded to UPDATE-3, I began getting notifications that my volume is degraded, particularly VOL-1. I saw a post in the CRITICAL UPDATES thread that a user had the same issue but they were hoping for the best and never gave an update. I did do an extensive search throughout all the threads and Google but never found anything that was similar or had a resolution.
Besides searching the threads and Google, here are the additional steps I took to T/S my issue:
1. Performed a Shutdown/Restart
2. Physically checked power and sata cables to each drive
3. Performed both QUICK and EXTENDED S.M.A.R.T. checks
4. Went into GRUB command line and 'append SataPortMap=4', I only have one SATA Controller with 4 Ports.
5. Using the DSM GUI Storage Manager, I performed a 'REPAIR' on the Disk and nothing changed/resolved
I really would hate to replace the HDD especially since it was working beautifully until I performed the UPDATE-3.
Any help would be greatly appreciated and I can provide for information as needed. Thanks in advance everyone!
