sloob Posted June 1, 2022 Share Posted June 1, 2022 Hi, Earlier today I went to start a VM on my server and a disk (Disk 5) immediately went into error. I stopped the array, de-assigned the disk, started the array again, stoped it and re-assigned the disk. After the data rebuild on that disk I tried again to start the VM and the same thing happened. Except this time my SMB shares wouldn't work, I had 7M + errors on my parity drive (Disk 0) and the log immediately filled to 100%. I managed to grab a log before shutting everything down. First of all I'd like to make sure I didn't lose data and second of all I'd like to know what caused this issue and is it safe to reboot and bring the system back online. Thanks everyone unraid-diagnostics-20220601-1912.zip Quote Link to comment
itimpi Posted June 2, 2022 Share Posted June 2, 2022 I have not looked at the diagnostics, but your symptoms suggest you are doing a hardware pass-through to the VM and the device now being selected is the disk controller. If you have recently upgraded Unraid you need to be aware that hardware ID’s can change after the upgrade and need to be checked before starting any VM using hardware pass-through. 1 Quote Link to comment

Wow you certainly do know your stuff! that was exactly it! I unchecked the disk controller in the VM config. is it safe to start the VM back up now that no hardware is being passed-through?

One last question, Do you think I lost data with what happened? Quote Link to comment

No obvious reason why you should have as long as the drives mounted OK after rectifying the error. If any drives are showing as unmountable I would suggest posting new diagnostics taken after starting the array. Quote Link to comment

If you have recently upgraded Unraid you need to be aware that hardware ID’s can change after the upgrade and need to be checked before starting any VM using hardware pass-through. Sorry to revive such an old thread, but I was never able to start the VM back up. Even if I uncheck every devices on the "edit" screen for that VM, it crashes my whole server every time. Is there any other way to force remove the controller from the VM while still passing my capture card? Ideally without deleting and re-installing the VM? Here is the XML for that VM <?xml version='1.0' encoding='UTF-8'?> <domain type='kvm'> <name>Capture Card</name> <uuid>17e53729-4f3b-ecb0-642e-50cb56087e3c</uuid> <metadata> <vmtemplate xmlns="unraid" name="Windows 10" icon="windows.png" os="windows10"/> </metadata> <memory unit='KiB'>4194304</memory> <currentMemory unit='KiB'>4194304</currentMemory> <memoryBacking> <nosharepages/> </memoryBacking> <vcpu placement='static'>7</vcpu> <cputune> <vcpupin vcpu='0' cpuset='0'/> <vcpupin vcpu='1' cpuset='1'/> <vcpupin vcpu='2' cpuset='7'/> <vcpupin vcpu='3' cpuset='3'/> <vcpupin vcpu='4' cpuset='9'/> <vcpupin vcpu='5' cpuset='5'/> <vcpupin vcpu='6' cpuset='11'/> </cputune> <os> <type arch='x86_64' machine='pc-i440fx-5.1'>hvm</type> <loader readonly='yes' type='pflash'>/usr/share/qemu/ovmf-x64/OVMF_CODE-pure-efi.fd</loader> <nvram>/etc/libvirt/qemu/nvram/17e53729-4f3b-ecb0-642e-50cb56087e3c_VARS-pure-efi.fd</nvram> </os> <features> <acpi/> <apic/> <hyperv mode='custom'> <relaxed state='on'/> <vapic state='on'/> <spinlocks state='on' retries='8191'/> <vendor_id state='on' value='none'/> </hyperv> </features> <cpu mode='host-passthrough' check='none' migratable='on'> <topology sockets='1' dies='1' cores='7' threads='1'/> <cache mode='passthrough'/> </cpu> <clock offset='localtime'> <timer name='hypervclock' present='yes'/> <timer name='hpet' present='no'/> </clock> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/local/sbin/qemu</emulator> <disk type='file' device='disk'> <driver name='qemu' type='raw' cache='writeback'/> <source file='/mnt/user/domains/CaptureCard/vdisk1.img'/> <target dev='hdc' bus='virtio'/> <boot order='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/mnt/user/Softwares/ISO/Microsoft Windows 10 Home and Pro x64 Clean ISO/en_windows_10_multiple_editions_x64_dvd_6846432.iso'/> <target dev='hda' bus='ide'/> <readonly/> <boot order='2'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/mnt/user/Softwares/ISO/virtio-win-0.1.141-1.iso'/> <target dev='hdb' bus='ide'/> <readonly/> <address type='drive' controller='0' bus='0' target='0' unit='1'/> </disk> <controller type='pci' index='0' model='pci-root'/> <controller type='ide' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <controller type='virtio-serial' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </controller> <controller type='usb' index='0' model='ich9-ehci1'> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x7'/> </controller> <controller type='usb' index='0' model='ich9-uhci1'> <master startport='0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0' multifunction='on'/> </controller> <controller type='usb' index='0' model='ich9-uhci2'> <master startport='2'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x1'/> </controller> <controller type='usb' index='0' model='ich9-uhci3'> <master startport='4'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x2'/> </controller> <interface type='bridge'> <mac address='52:54:00:a6:d2:e6'/> <source bridge='br0'/> <model type='virtio-net'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <serial type='pty'> <target type='isa-serial' port='0'> <model name='isa-serial'/> </target> </serial> <console type='pty'> <target type='serial' port='0'/> </console> <channel type='unix'> <target type='virtio' name='org.qemu.guest_agent.0'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> <input type='tablet' bus='usb'> <address type='usb' bus='0' port='1'/> </input> <input type='mouse' bus='ps2'/> <input type='keyboard' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes' websocket='-1' listen='0.0.0.0' keymap='en-us'> <listen type='address' address='0.0.0.0'/> </graphics> <audio id='1' type='none'/> <video> <model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='1' primary='yes'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> <memballoon model='virtio'> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </memballoon> </devices> </domain> And here is the device I'm trying to parse (See attachment) Thanks Quote Link to comment
