OK now I’m a little bit confused.
I once more checked the logs and all my 6 drives are identified correctly and the link speed is also set to the correct value.
The messages/failiures I get are for ata 7&8 which are not present on my mainboard. I only have connectors for sata 1-6-
So I wonder why I get these messages
Apr 14 09:24:26 localhost kernel: ata7: SATA max UDMA/133 cmd 0xf090 ctl 0xf080 bmdma 0xf050 irq 19
Apr 14 09:24:26 localhost kernel: ata8: SATA max UDMA/133 cmd 0xf070 ctl 0xf060 bmdma 0xf058 irq 19
Apr 14 09:24:42 localhost kernel: ata7: link is slow to respond, please be patient (ready=-19)
Apr 14 09:24:42 localhost kernel: ata8: link is slow to respond, please be patient (ready=-19)
Apr 14 09:24:46 localhost kernel: ata8: SRST failed (errno=-16)
Apr 14 09:24:46 localhost kernel: ata7: SRST failed (errno=-16)
on the other hand ata5&6 are connected with 3.0 Gbps
Apr 14 09:24:37 localhost kernel: ata6: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
Apr 14 09:24:37 localhost kernel: ata5: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
but are limited later on also to 1.5 Gbps like ata7&8
Apr 14 09:25:22 localhost kernel: ata5: SATA link up 1.5 Gbps (SStatus 113 SControl 310)
Apr 14 09:25:22 localhost kernel: ata6: SATA link up 1.5 Gbps (SStatus 113 SControl 310)
perhaps ata7 & 8 are reserved for eSATA connectors but in the manual of my mainbord it is stated, that they should not be present in my version of the MSI P67A-GD53 and only available in P67A-GD65.
If I take a look into the disk info (Rockstor WebUI), I can exactly follow the results:
The disks connected to sata 5&6 are limited to 1,5 Gbps.
Disks connected to sata 1-4 work with the expected speed of 3 or 6 Gbps.
After I changed sata connection of some drives Rock-Ons like owncloud but also other will not start again and reinstallation failed.
I really don’t know if it was a good idea to upgrade to Rockstore 5 on SuSE Leap 
Following messages in rockstor.log (rock-on owncloud official cannot be installes again)

I changed to a new SSD bootdevice today and only have a few issus regarding quotas but hope to fix it during the next days. Also ROCK-ONS like mariadb owncloud and plex are back and running.
