[zfs-discuss] EOF broken on zvol raw devices?

2007-08-23 Thread Jürgen Keil
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

[zfs-discuss] zfs destroy takes long time

2007-08-23 Thread Igor Brezac
We are on Solaris 10 U3 with relatively recent recommended patches applied. zfs destroy of a filesystem takes a very long time; 20GB usage and about 5 million objects takes about 10 minutes to destroy. zfs pool is a 2 drive stripe, nothing too fancy. We do not have any snapshots. Any ideas?
