July 10, 20205 yr So I've migrated my UNRaid server (6.8.3) to new hardware and added new drives with a HBA. Everything was working fine and I even rebuilt my Parity earlier yesterday without issue. I went to setup VMs and realized that the HVM was disabled. I rebooted and enabled SVM in the BIOS and booted back up. Now all 4 drives on my HBA are missing. Thinking that the setting change was the culprit, I disabled the setting and rebooted to no avail. The HBA and drives show after the BIOS splash screen with all the drives and no errors. I'm at a lost as everything was going smoothly before with no obvious issues. Please help kiba-diagnostics-20200710-0222.zip
July 10, 20205 yr Community Expert Some Marvell controllers, especially the 9230 which you're using has known issues with iommu enable, this works for some. 3 hours ago, DracoPurple said: I disabled the setting and rebooted to no avail. It's still enable on the diags posted.
July 10, 20205 yr Author Quote 1) edited /boot/syslinux/syslinux.cfg 2) added 'iommu=pt' to the line containing 'append initrd=/bzroot' You absolutely magnificent person. Thank you so much! This worked like a charm. I had to use the 'Intel' version despite on AMD but no complaints here. The HBA is a stop gap anyway until I get a large LSI HBA. Quote It's still enable on the diags posted. I must have taken the diags after re-enabling HVM (SVM) but IOMMU was on from the start. In anycase, thanks again. This just saved me from the madhouse. I owe you a bottle of Scotch.
