Hi fellows. A bit of a complicated situation that I'm trying to make sense of.
Yesterday, my Xpenology 7.2 server experienced a power outage, which took out 3 HDDs in the SHR2 volume. After some research, I have determined that the HDDs failed due to their read/write heads being stuck on the platter. Since I only need one of the three failed HDDs to work in order to restore the volume, I decided to attempt a repair. The first HDD was destroyed in the process. But the second HDD was successful in freeing the read/write head. However, here is where it became complicated.
I hooked up the repaired HDD to an external reader and plugged it into my linux computer. It worked normally and I was able to see the Synology partitions. I then put it back into my Xpenology server and turned it on. Note that the other two failed HDDs are now out of the server. The first boot resulted in a page that says "Sorry, the page you are looking for is not found." when I tried to access the DSM. I rebooted the server again and was able to get into DSM this time, but the repaired HDD was still not showing up. I plugged the repaired HDD back to my linux computer again. This time, it shows only 2 small synology partitions, like it had been re-initialized by the server.
At this point I'm stumped. It looks like I got the HDD working, but my Xpenology server is wiping it out with new partitions. I have one more HDD that I can attempt a rescue. But really need to understand what's going on first before I do it. Does anyone have an explanation why the server is not recognizing the repaired HDD, yet still proceeded to initialize it with new partitions?
