Yep. And striped vdevs are okay too. Note that the installer UI already detects (and warns) if user has selected a layout which won't be supported by GRUB. > compression works, but > probably only if you use the default algorithm; gzip compression should be fine too, at least with GRUB 1.99. However the partman-zfs UI doesn't support it, so it needs to be set manually (patches welcome ;-)). > You *can* use a local ZFS zvol as swap space but > I don't recommend that as it appears to be unstable. It depends a lot on your workload. The problem is that zvol itself is memory-hungry so when the kernel tries to move data from memory to disk it needs spare memory for the operation, which can get stuck in a catch22. But this is only a problem if physical memory is filled completely by other means. -- Robert Millan -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
