Error when moving Windows installation ISO

[splitting11]

I'm using pve-9.0. An error occurred when I moved files between ZFS datasets.
mv: error copying './zh-cn_windows_11_business_editions_version_24h2_updated_aug_2025_x64_dvd_08e70c15.iso' to '/rpool/test1/zh-cn_windows_11_business_editions_version_24h2_updated_aug_2025_x64_dvd_08e70c15.iso': Invalid cross-device link

The error only occurred when this ISO file was moved; other files worked normally.

Hi,
I'm facing the same issue.
All ISOs worked, except the Windows 11 ISOs files, like
de-de_windows_11_business_editions_version_25h2_updated_dec_2025_x64_dvd_9539a9c6.iso
or
en-us_windows_11_business_editions_version_25h2_updated_dec_2025_x64_dvd_e9c929fc.iso

Any idea?

Are the ISOs mounted / attached to any VM?

no, the files are not used by any other VM.
