Rightnow I use reclaime pro recovery software from a friend of mine and I can see the data, and try to get it of the raid. hopefully it works

Okay, I'll wait for flyride

I shut down the server and removed the GPU that was causing problems. I started the server and the virtual machine and this is the output of the commands you have send me. this is with the harddrives the xpenology VM had in the first place I won't touch it unless you say so ^^. sorry for doing many things wrong output of "cat /proc/mdstat" ash-4.3# cat /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [raidF1] md3 : active raid5 sdg3[0] sde3[1] 15606591488 blocks super 1.2 level 5, 64k chunk, algorithm 2 [5/2] [UU___] md2 : active raid1 sdb3[0] sdc3[1] 11955200 blocks super 1.2 [2/2] [UU] md127 : active raid1 sde1[1] sdg1[0] 2490176 blocks [12/2] [UU__________] md1 : active raid1 sdb2[0] sdc2[1] sde2[2] sdg2[3] sdh2[4] 2097088 blocks [12/5] [UUUUU_______] md0 : active raid1 sdb1[0] sdc1[1] 2490176 blocks [12/2] [UU__________] unused devices: <none> output of "mdadm --detail /dev/md3" ash-4.3# mdadm --detail /dev/md3 /dev/md3: Version : 1.2 Creation Time : Sat Jun 20 00:46:08 2020 Raid Level : raid5 Array Size : 15606591488 (14883.61 GiB 15981.15 GB) Used Dev Size : 3901647872 (3720.90 GiB 3995.29 GB) Raid Devices : 5 Total Devices : 2 Persistence : Superblock is persistent Update Time : Sun Nov 22 18:24:28 2020 State : clean, FAILED Active Devices : 2 Working Devices : 2 Failed Devices : 0 Spare Devices : 0 Layout : left-symmetric Chunk Size : 64K Name : Dabadoo:2 UUID : ff64862b:9edfe233:c498ea84:9d4b9ffd Events : 39112 Number Major Minor RaidDevice State 0 8 99 0 active sync /dev/sdg3 1 8 67 1 active sync /dev/sde3 - 0 0 2 removed - 0 0 3 removed - 0 0 output of "mdadm --examine /dev/sd[efgh]3" ash-4.3# mdadm --examine /dev/sd[efgh]3 /dev/sde3: Magic : a92b4efc Version : 1.2 Feature Map : 0x0 Array UUID : ff64862b:9edfe233:c498ea84:9d4b9ffd Name : Dabadoo:2 Creation Time : Sat Jun 20 00:46:08 2020 Raid Level : raid5 Raid Devices : 5 Avail Dev Size : 7803295744 (3720.90 GiB 3995.29 GB) Array Size : 15606591488 (14883.61 GiB 15981.15 GB) Data Offset : 2048 sectors Super Offset : 8 sectors Unused Space : before=1968 sectors, after=0 sectors State : clean Device UUID : a5de7554:193b06b9:b1f1a8df:3c917e8b Update Time : Sun Nov 22 18:24:28 2020 Checksum : 381624 - correct Events : 39112 Layout : left-symmetric Chunk Size : 64K Device Role : Active device 1 Array State : AA...

Sorry for not saying the purple screen happend, totally forgot it due some personal issues. I have removed the gpu which cause the purple screen and will be uploading the output of the commands. And wont touch the server until you guys say so . Sorry for the trouble, I appreciate you guys helping me.

The whole server rebooted because i got a purple screen view days ago. Also removed a few hard drives but those did not belong to the original raid, maybe i added them accidentally to the virtual machine en removed them when i pulled them out of the server. you still think this can work ?

I see, I thought I used raid 5, but not sure, and filesystem is ext4 for sure. lets try. Btw, how did you configure your nas? I want to do it the best way but at the moment I learn by making mistakes, and I don't know what is the best way to set it up.

I don't, I guess that is something that shows how the raid is configured?

Okay, Sorry for the late reply, the lifecycle controller on my server was not doing great and had to troubleshoot it.

forgot this one

I created the 2x 16gb so I could boot the Synology Nas. I had a ds918+ but the hardware was slow :(. I asked if you think I won't be able to repair this because if not then, I know it is pointless on working on this problem. I should learn more abut the raid and how it works, I am too unfamiliar with it

you think I won't be able to repair this?
