2007-08-23 Thread Igor Brezac

I tried to copy a 8GB Xen domU disk image from a zvol device to an image file on an ufs filesystem, and was surprised that reading from the zvol character device doesn't detect "EOF". On snv_66 (sparc) and snv_73 (x86) I can reproduce it, like this: # zfs create -V 1440k tank/floppy-img # dd if=
