We have this NAS server setup at our church and I’ve been working on this issue for many days now with no progress…
It started when the 4th drive failed on the 4 3TB RAID5 volume which hung things up until it got restarted and then became accessible again in degraded mode as I had taken the failed drive out. I purchased a 3TB WD Red NAS drive as replacement but it didn’t recognize it and said “invalid drive”. I’ve also since contacted WD on this for support but no progress yet. I need help finding the exact replacement drive and where to get it from as that compatibility drive list on the website isn’t helping me to find exactly what drive to get and from where.
The other issue we have in addition is lack of space on C:. Who designed only a 60GB C: partition and 8TB for D:. I cannot expand our C: partition to use the many free TB on D:. I’ve been doing lots of searching regarding clearing up the WinSXS folder but no luck there either, I’ve tried the disk cleanup and other methods but cannot seem to delete the 20GB of WinSXS, very frustrating. All is so very slow since I have 10MB free space left on C: and have been working for days trying to find something to delete so at least it becomes somewhat usable again.
We’ve been having many OS issues (probably because of lack of C: space?) like not being able to login with RDP (since its headless design that’s the only way to connect), Explorer.exe crashing when right-clicking or going to System properties and the Server service keeps stopping which then prevents users from access the server share).
Any suggestions would be greatly appreciated at this point!.
