Hello, I ran a xpenology-system for about 4 years (HP Microserver n54l, 10 GB Ram, Raid 0), but yesterday the hardware vaporized 😥 If I now buy a original Synology and put in the disks, will the data still be available? I was thinking about an original since I don't need the BIG hardware anymore Best regards esemuhdeoh
Alright, strap yourselves in, because this might get long... Hardware setup: 4x WD 2TB Red in SHR ASRock H81M-HDS Mobo Intel Celeron Processor 8GB Crucial Ballistix RAM First, some background: A few days ago I noted the network drives that I have on my system were not showing up in Windows so I navigated to the system via my browser and the system told me I needed to install an update and that my drives were from an old system and would need migration. I wrote a different post about that here: The versions it wanted to install was the same version (or slightly higher) of 5.2 so I thought nothing of it and agreed to let the system update. It went through the install smoothly, but never rebooted. Eventually I was able to navigate back to the web browser and it told me I now had 5.2 firmware, but 6.1-15152 DSM. I am still unclear how this install happened, but I assume that it downloaded it automatically from the internet even though I had enabled the "only install security patches" option. As I posted in the Tutorial forum a few posts after the linked one, I was able to get Jun's loader installed and boot into 6.1-15152 and I thought all was well. However, when I booted into the DSM, I was in a world of hurt. I have one bad disk in the array clearly that lists bad sectors, but that's the point of the SHR array right? Well I let the RAID start to repair itself and always around 1.5% into the repair it crashes and tells me the System Volume has crashed. However, you'll notice in the Disk Info Section there are only 3 disks. Looking into the logs show that Disk 5 (the bad one) failed at trying to correct bad sectors: However, when this happens Disk 1 (AFAIK, perfectly fine drive) switched into Initialized, Normal but drops out of the RAID array and then it goes into crash mode. I don't understand the relationship between Disk 5 crashing out when repairing the RAID and Disk 1 disappearing. It stands to reason that if Disk 1 is fine, which is seems to be that it would just fail and stay in degraded mode until I can swap in a new drive. I have tried starting the system with Disk 5 unplugged, but that does no good. I have also begun playing around with attempts at data recovery in a LiveUSB of Ububntu using some of Synology's guides as well as just googling around. So I suppose I have a few questions. 1. Does anyone know of a relationship between possibly installing the new system, and the bad disk causing the good disk to crash? 2. How likely is it that Disk 1 (AFAIK good disk) is also toast. 3. Do you have any tips for recovering data from a situation like this? I would greatly appreciate any help or advice you can provide. I have been banging my head against a wall for 3 nights working on this. I have all the really important stuff backed up to the cloud so it is not a matter of life and death (5 year, 10000 photos) but there is a lot of other media that I am willing to do a lot to not replace or only replace some of.
