@IG-88, I'm really sorry about this but for whatever reason the config of the VM did not contain the passthrough of the USB controller anymore. Also older backups did not contain it. So I've added it again and voilà the USB drives are recognized! Really have no idea how this could have happened and why the backups to the USB drives could have happened. But I've learned how to recover an array through a live linux, so thanks for that! And for your patience!

@IG-88, your suggested values unfortunately have no positive effect. Still, no USB disk is recognized. See attached the dmseglog. Thanks for your patience.👍dmesglog.txt

@IG-88 thanks for the suggestion. Tried these values now, but still no USB disks: maxdisks="20" esataportcfg="0x0" usbportcfg="0xffff00000" internalportcfg="0xfffff" But why wouldn't the USB drives show up again, when I reset the confs and disconnect the new 16TB drives? That would be the same situation as before, no?

Thanks @IG-88, you're a life saver!🤝 Resetted the synoinfo.confs and set your suggested values for 20 drives. The result is still that the USB drives don't show up. But they also did not show when i resetted the confs. So any idea, why the USB drives are still missing? I know for a fact that the USB drives were detected before I first changed the confs to extend the disk limit, because of the successful daily backups that were done right up to this point. I did not change anything on the VM settings, so this should be fine as well. Also detached the USB drives multiple times.

@IG-88, thanks for the help so far, mate! Really appreciated! So I ran your recommendation: root@ubuntu:~# mdadm --examine /dev/sd[abcdf]1 | egrep 'Event|/dev/sd' mdadm: No md superblock detected on /dev/sdb1. mdadm: No md superblock detected on /dev/sdf1. /dev/sda1: Events : 13363196 /dev/sdc1: Events : 13363196 /dev/sdd1: Events : 13363196 What exactly does this mean? EDIT: I just rebooted the live ubuntu, because the results for various commands like "cat /proc/mdstat" were non-existent. Now the array seems to be active under md0: root@ubuntu:~# cat /proc/mdstat Personalities : [raid1] [raid6] [raid5] [raid4] md4 : active raid1 sdb3[0] 9761614848 blocks super 1.2 [1/1] [U] md2 : active raid1 sdf3[0] 100035584 blocks super 1.2 [1/1] [U] md3 : active raid5 sda3[3] sdd3[2] sdc3[1] 11711401088 blocks super 1.2 level 5, 64k chunk, algorithm 2 [3/3] [UUU] md0 : active raid1 sda1[1] sdc1[3] sdd1[2] 2490176 blocks [12/3] [_UUU________] unused devices: <none> root@ubuntu:~# mdadm --detail /dev/md0 /dev/md0: Version : 0.90 Creation Time : Wed Aug 28 18:21:19 2019 Raid Level : raid1 Array Size : 2490176 (2.37 GiB 2.55 GB) Used Dev Size : 2490176 (2.37 GiB 2.55 GB) Raid Devices : 12 Total Devices : 3 Preferred Minor : 0 Persistence : Superblock is persistent Update Time : Sun Jan 3 22:28:51 2021 State : clean, degraded Active Devices : 3 Working Devices : 3 Failed Devices : 0 Spare Devices : 0 Consistency Policy : resync UUID : d81e429a:6dda9ebf:3017a5a8:c86610be Events : 0.13363196 Number Major Minor RaidDevice State - 0 0 0 removed 1 8 1 1 active sync /dev/sda1 2 8 49 2 active sync /dev/sdd1 3 8 33 3 active sync /dev/sdc1 - 0 0 4 removed - 0 0 5 removed - 0 0 6 removed - 0 0 7 removed - 0 0 8 removed - 0 0 9 removed - 0 0 10 removed - 0 0 11 removed Mounting the array still seems not working though: root@ubuntu:~# mdadm -Ee0.swap /dev/sda1 /dev/sdc1 /dev/sdd1 mdadm: No super block found on /dev/sda1 (Expected magic a92b4efc, got fc4e2ba9) mdadm: No super block found on /dev/sdc1 (Expected magic a92b4efc, got fc4e2ba9) mdadm: No super block found on /dev/sdd1 (Expected magic a92b4efc, got fc4e2ba9) root@ubuntu:~# mdadm -AU byteorder /dev/md0 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 mdadm: No super block found on /dev/sda1 (Expected magic a92b4efc, got fc4e2ba9) mdadm: no RAID superblock on /dev/sda1 mdadm: /dev/sda1 has no superblock - assembly aborted

@IG-88, thanks for the pointers. Still I'm not able to mount the drives.

Any ideads? Should i use md127 instead of md0 from the tutorial?

@IG-88, thanks for the patience. Yes, totally my bad.🙃 Just tried the tutorial, not sure how i need to proceed in my case. I have 4 volumes: - vol 1: ssd 100GB for systems stuff and documents (basic) - vol 2: 3x6TB disks in RAID5 (the one that should be replaced) - vol 3: 10TB disk for archive (basic) - vol 4: 3x16TB disks in RAID5 (new) So i thought I'd run step 7 & 8 for vol 2, but i get the message for step 8. root@ubuntu:# mdadm -AU byteorder /dev/md0 /dev/sda1 /dev/sdc1 /dev/sdd1 mdadm: /dev/md0 assembled from 3 drives - need 4 to start (use --run to insist). Would you happen to know how I need to proceed here?

@IG-88, I restored to original synoinfo.confs and then just edited the maxdisk parameter. Which of course was stupid, but I wouldn't have expected DSM not to work at all anymore... So I'll try the tutorial in the link tomorrow. Hope I'll be able to fix it...🤔 So what are the params you'd recommend? Don't I need to adjust all 4 params to make them fit to 16 disks instead of 12? == original conf for 12 disks == esataportcfg="0xff000" usbportcfg="0x300000" internalportcfg="0xfff"

Thanks @IG-88, just tried maxdisks = 16. But now DSM is not reachable anymore (web-interface, ssh, also not on Synology Assistant). Will have to find a way to fix this first...

I was running a Xpenology-VM with DSM 6.2.2-24922 Update 4 under Proxmox. I have 3 HDDs in RAID5, 1 HDD in Basic and 1 SSD in Basic. Furthermore 3 external USB-HDDs for various backups. This was working fine so far. Now I bought 3x16TB HDDs to replace the old RAID5 array since the disks are getting old and the volume getting too small. After I connected them, only 2 of the 3 disks were shown in DSM. With the count of disks hitting 12 in Storage Manager>HDD/SSD (even though I don't really understand, why Drive 3-6 are skipped), I realised that the max disks of 12 was reached and therefore I've modified the synoinfo.confs (both in /etc.defaults/ and /etc/) to the following: maxdisks="24" internalportcfg="0xffffff" usbportcfg="0xf000000" esataportcfg="0x0" (since I don't have any) But like this all the internal disks are showed correctly. But none of the external USB disks are recognised anymore in Control Panel > External Devices. I've done multiple reboots. What am I missing here? Thanks for any leads to solve this.

Thanks. No idea whats the problem over here. I have a pretty similar config. The VM behaves as if it lost all boot devices after the controller is detected and the VM rebooted. If I had the same problem with DSM 5.2 the case would be clear, but since that is still working like a charm I'm very confused. Would be super happy if someone had a hint.

Could you post your VM.conf here? What firmware for the controller are you using? I'm using P19, which should be the forelast firmware.

I'm having trouble passing through (pci passthrough) my LSI 9211-8i controller (flashed to IT mode) in Proxmox 4.4. The VM boots without the controller passed through. As soon, as I want to pass it through the VM finds the controller as usual (see https://www.dropbox.com/s/kert6x8q6l48n ... 2.PNG?dl=0), but then reboots and is stuck at "Booting from Hard Disk..." (see attached screenshot).
