November 15, 20223 yr Hi all I wanted to virtualize my phisical PC. So i come up with idea of backuping my whole drive C (1 TB ssd) and than creating virtual mashine in unraid and using recovery.iso to boot up and restore this PC in virtual mashine. Whole process went well and now i have vdisk.img but. when i look to the folder where it is i see root@Skynet:/mnt/user/vm-test/Windows 10# ls -al total 570856136 drwxr-xr-x 1 nobody users 24 Nov 13 12:57 ./ drwxrwxrwx 1 nobody users 49 Nov 14 18:36 ../ -rwxrwxrwx 1 nobody users 1099511627776 Nov 14 02:51 vdisk1.img* it seems that it takes only 570 GB in real but it shows 1TB in filesystem. and when i try to make a copy of it to array problems begins. my HDD that is capable of transfers 140-250 Mb/s when copy this particular file slow down to 5MB/s. copying this file take ages. I thought it is faulty drive so i did another test. I copyied part of this file to another folder using "cp" command and stop copy proces after 100GB. Than i try to copy that second file and sudenly my HDD goes full speed. It seems that problems are only with oryginal file created by VM itself. thesame goes for my nvme drives. they have speeds around 3,5GB/s and when i create img file on them by VM manager and try to copy this file between nvme drives speed drops to 50-90 Mb/s. But when i try to copy already coppied file i go full speed. All VM are stopped while i coppy those files. I dont know what problem is and need your help please.
