New to this forum.
I have a gen8 microserver running at home, where I have installed an SSD in the ODD sata slot. On the SSD I have installed Ubuntu Server 18.04.
I have then created a logical volume witht the raid controller and can then boot to the SSD. So far so good.
My problem emerges when I reboot the system. The logical volume disapears and it gives the error: "boot logical drive is configured but is missing or offline".
I then have to go into the utility and reconfigure the logical volume. Kind of annoying, when trying to run a headless setup.
I hope this topic fits here just right.
So a few days ago, I moved my Microserver Gen8 to a friend's place and resetted it.
When we set it up with new disks, the raid-creation in OpenMediaVault (Debian 9.6) failed.
`smartctl` tests passed just fine though and vendor-tools also didn't report any drive errors.
- I start the Raid creation via `mdadm` and after a while (random blocks and times), it fails and the second disk seems to fail (e.g. sda and sdb are creating a raid, then sdb gets "kicked out" and reread as e.g. sdd, sometimes even with only a few GB of space instead of 3TB).
I tried attaching the second disk on ata2 and ata3, but it keeps failing. The one on ata1 works just fine though.
I tried different disks and vendors, but get the same results.
There are some errors in `dmesg`, but I don't know what they mean. I pasted them here: https://pastebin.com/raw/XASQJ6cy
What I did here: I stopped the raid to re-create it, but then didn't do anything for a while and the error still came up.
Can someone help me with this? (As a wild guess, I'd say that somethings wrong with the SATA connections at least on ata2 and ata3).
Thanks in advance
