Synology - The Storage Pool Cannot be Assembled Online - DS3617xs

[ExecDude]

We had some brownouts yesterday with the heatwave on the East Coast, so decided to power off the Synology NAS which was working fine and connected to a working UPS. The shutdown was done normally from the web interface.

 

When we powered back on the system a few hours later we got the error "Corrupted Index Database," then the NAS notified that "Storage Pool 1 Can be Assembled. Please go to Storage Manager for more Information."

 

We went to storage manager where it asked us to click "Online Assembly," then we got the error, "The Storage Pool Cannot be Assembled Online."

 

All the Drives are showing "Detected" and "Healthy"

 

We also notice that the Synology Drive App that's being used for Team Folders is giving the Error that it's not Running when we open it, even though it is running when we look under package center.

 

The Pool that has this issue is on the DX1215II-1 (Expansion #1)

 

Again everything was working normally before shutdown, shutdown was normal, system is on a UPS surge protector that was working.

 

Anyone ever ran into this issue and know how we can fix it? We have a ton of data on this storage pool and would like to try and fix.

 

Hoping we get a fast response here rather than waiting for ages with synology tech support.

 

Appreciate any help or advice.

The Drive 5 cannot be seen in this picture. Is it accidentally broken? Or has it been ever present since creation of this pool? Since the pool is arranged in JBOD, expect data corruption on Drive 5, or even on the whole pool; there's no practical solution other than looking for data recovery companies.

Drive 5 is assigned to another storage pool. Synology identified an issue with Drive 8. Wondering if I do data recovery on drive 8 and transfer the info to another, can it be hot swapped to rebuild the pool?
