Hi, I have a VM file with reflinks to it, the reflinks were taken every night. My question is how to copy/migrate all these file to a different xfs partition (which also have reflink enabled) without loosing the reflinks property, else may lead to copy all the shared blocks per file which will cost large disk space. I have tried to copy them using rsync as below: On Partition 1: ActualFile.img -- [1] Actaul Size 10GB + [2] Append 2GB + [3] Append 1GB ReflinkCopy1 -- [1] Actual Size 0 -- Shared blocks 10GB ReflinkCopy2 -- [2] Actual Size 0 -- Shared blocks 12GB I have first rsync the files into Partition 2 as below: # cd PARTITION2 # rsync /PARTITION1/ReflinkCopy1 ActualFile.img # du -sh ActualFile.img 10GB # cp --reflink=always ActualFile.img # rsync /PARTITION1/ReflinkCopy2 ActualFile.img # du -sh ActualFile.img 12GB # cp --reflink=always ActualFile.img # rsync /PARTITION1/ActualFile.img ActualFile.img But the size used by partition was 35GB (verified using df -h) instead of 13GB Also, where can I find reflink related tools ?
