Dela7460 Posted March 24, 2023 Share Posted March 24, 2023 Everything was going pretty good until I saw a plugin that wanted the newest version of unraid; so I upgraded. The next day I found the server unresponsive; I did a reboot and found that my dockers and vms were gone. I started looking for back ups but I looks like I didn't make any. Even though I recall spending a lot of time looking up backup and stuff. And i did find a backup but it was a backup from a save file from a VM. Not the VM itself. find /mnt -name libvirt.img /mnt/user/system/libvirt/libvirt.img /mnt/user0/system/libvirt/libvirt.img /mnt/disk3/system/libvirt/libvirt.img No backups found details on the files root@Tower:/mnt/user/system/libvirt# stat libvirt.img File: libvirt.img Size: 1073741824 Blocks: 2097152 IO Block: 4096 regular file Device: 0,52 Inode: 649362777788858824 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 99/ nobody) Gid: ( 100/ users) Access: 2023-03-24 11:40:07.460759411 -0500 Modify: 2023-03-24 13:32:54.094738686 -0500 Change: 2023-03-24 13:32:54.094738686 -0500 Birth: - root@Tower:/mnt/user0/system/libvirt# stat libvirt.img File: libvirt.img Size: 1073741824 Blocks: 2097152 IO Block: 4096 regular file Device: 0,51 Inode: 649362777788858824 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 99/ nobody) Gid: ( 100/ users) Access: 2023-03-24 11:40:07.460759411 -0500 Modify: 2023-03-24 13:32:54.094738686 -0500 Change: 2023-03-24 13:32:54.094738686 -0500 Birth: - root@Tower:/mnt/disk3/system/libvirt# stat libvirt.img File: libvirt.img Size: 1073741824 Blocks: 2097152 IO Block: 4096 regular file Device: 9,3 Inode: 6517375432 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 99/ nobody) Gid: ( 100/ users) Access: 2023-03-24 11:40:07.460759411 -0500 Modify: 2023-03-24 13:32:54.094738686 -0500 Change: 2023-03-24 13:32:54.094738686 -0500 Birth: 2023-03-24 11:40:07.460759411 -0500 Looking at the Libvirt Log file I get find the following 2023-03-24 17:50:52.825+0000: 8645: info : libvirt version: 8.7.0 2023-03-24 17:50:52.825+0000: 8645: info : hostname: Tower 2023-03-24 17:50:52.825+0000: 8645: error : virPCIVPDParseVPDLargeResourceFields:555 : internal error: Checksum validation has failed 2023-03-24 17:50:52.829+0000: 8645: error : virPCIVPDParseVPDLargeResourceFields:555 : internal error: Checksum validation has failed looks like there is still hope, I am running a parity check now to see if any of that can be restored. I also read that you could recreate the VM using the same Vdisk but I can't seem to locate those anywhere. The directory where I would have stored those is empty. I had a Windows 10 and Ubuntu VM The docket can be restored fairly easily. It's the VMs I'm concerned about. Any assistance would be much appreciated. Fun times... tower-diagnostics-20230324-1328.zip Quote Link to comment
Solution JorgeB Posted March 24, 2023 Solution Share Posted March 24, 2023 Parity check won't restore any data, based on the btrfs transid both docker and libvirt images are new, I see you have an unassigned SSD, maybe that was your cache drive before? And the old libvirt and docker images are there? Quote Link to comment
Dela7460 Posted March 24, 2023 Author Share Posted March 24, 2023 The 3 drives are from a old camera storage; I looked in them already. Quote Link to comment
Dela7460 Posted March 24, 2023 Author Share Posted March 24, 2023 You know; i think your right; i think my cache drive is whats missing. I'll see if i can toss that back on or view its contents. Quote Link to comment
Dela7460 Posted March 24, 2023 Author Share Posted March 24, 2023 JorgeB you nailed it. The cache drive was unmounted. And I am at fault for it. It was not caused by the upgrade but something I did. I had removed IP_Storage which consisted of 2 drives. But when I had removed this pool and must have removed that cache drive as well. I remounted the cache drive and my VMs and docker are back. My bad, Thank you very much JorgeB. 1 Quote Link to comment
