August 22, 20232 yr Hi All I have a strange issue. I want to migrate my shares and folders to a new structure. The new and old claim has the same configuration: All my files and folders are spread over different disks, which is ok. But if I now want to move the files inside of one disk with the command: mv /mnt/disk1/series/* /mnt/disk1/data/media/tv/ It takes ages to complete. Then I looked on the dashboard and saw I had read on all disks... Typically a movement inside the same disk should be done in some seconds, but in my case, it will be read from all disks. How can I fix this? It looks like it will copy the data from other disks.
August 22, 20232 yr Community Expert For zfs Unraid creates a dataset for shares, so they are in fact a different filesystem, and because of that will always require a rewrite. Reads for the other array disks are normal if you have turbo write enabled.
August 22, 20232 yr Community Expert Do you have Turbo Write enabled? You are likely to get better informed feedback if you attach your system’s diagnostics zip file to your next post in this thread.
August 22, 20232 yr Author Yes, turbo write is enabled. So what is your suggestion then? :-) I attached the diags tauri-diagnostics-20230822-1503.zip

August 22, 20232 yr Author Well, I want to reorganise the share... also move files and root folders to subfolders (inside the disk)... So there is no chance to get this faster? Usually, a move takes seconds, and I must wait hours to move files inside the same disk. this seems to be the trade-off from zfs...

August 22, 20232 yr Author I can move it inside of the share and then rename it. So, in the end, this should be fast if this happens on the same disk and in the same share?
August 22, 20232 yr Author Sorry, I get confused a bit... Does this mean movement is still slow even if I move folders and files inside of the same share/dataset?
August 22, 20232 yr Community Expert Moving files to the same disk inside the same dataset/share is fast.
