Hello everyone, I am using DSM 6.2.2-24922 update 6 system on my Dell Vostro 3900 MT i5-4460 computer, with four storage pools (Synology Hybrid RAID SHR without data protection) of sizes 2x 926 GB, 1x 3.63 TB and 1x 14.55 TB. Two days ago, one of the 14.55 TB disks had a failure and in the "Storage Manager" module, I received a message saying "Cannot use this storage pool. Data may be damaged. Try copying data before removing the storage pool." The status field shows "Damaged" while the "Health Status" field shows "Normal." Unfortunately, I am not sure what could be causing this issue. In the "HDD/SSD" module, I found the information that "This disk has been removed from the storage pool by the system. Please replace the disk and go to the Storage Pool tab to select the pool that needs repair, then click Actions > Repair" - unfortunately, after following these steps, the "Repair" option is greyed out and cannot be clicked. Using "File Station", I was able to access some of the directories stored on this disk and managed to transfer some of the necessary data - however, I have also lost system applications such as VPN server and others that were installed on this disk. I kindly ask for help from the esteemed members of this forum in solving this challenge - any advice or suggestions would be greatly appreciated. PS Sorry if I raised this topic in a wrong place - if so, please point me where I should post it.
