Hi all:
First; it is possible modify the boot zpool rpool after OS
installation...? I install the OS on the whole 72GB harddisk.. it is
mirrored so If I want to decrease the rpool; for example resize to a
36GB slice it can be done?
As far I remember on UFS/SVM I was able to resize boot OS disk via
detach mirror (so tranforming to one-way mirror); ajust the partitions
then attach de mirror. After sync boot form the resized mirror;
re-doing the resize on the remaining mirror and attach mirror and reboot.
Dowtime reduced to a reboot times.
Yes, you can follow same procedure with zfs (details will differ of course).
You can actually change the partitions while you're using the slice.
But after changing the size of both slices you may need to reboot
I've used it also when going from ufs to zfs for boot.
But the OP wants to decrease a slice size which if it would work at all
could lead to loss of data.
