In some pc bios user is able to set master or slave on the controller as the boot drive. In that case would `findroot' override the bios settings? Perhaps Bob D needs to look at bios and see what is actually set there. I seemed to need to do that recently doing a very similar operation. Old disk was on slave slot and was the booting os. I added a mirror disk in master slot, resilved, ran intallgrub but still had to change the bios boot order so that now master was boot disk. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Note that c4t1d0s0 is my *new* disk, not my old. I presume that's the right one to target with installgrub?

You need to install GRUB in the master boot record (MBR). # installgrub -m boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c4t1d0s0 And yes, it is safe to do while the resilvering is happening. The master boot record is outside of the block range of your pool. Changing the boot order shouldn't be necessary (that's what findroot is supposed to help take care of). It should only be necessary if the new disk wasn't seen by the BIOS in the first place or for some reason isn't selected as part of the normal BIOS boot sequence.

You need to use 'installgrub' to get the right boot pits in place on your new disk. The manpage for installgrub is pretty helpful.

[zfs-discuss] How to increase rpool size in a VM?
Hi, I have a build 109 system installed in a VM, and my rpool capacity is getting close to full. Since it's a VM, I can easily increase the size of the disk, or add another, larger disk to the VM. What's the easiest strategy for increasing my capacity? I tried adding a 2nd larger disk, did a zpool attach, waited for resilvering to complete, did a zpool detach of the 1st disk, but then it seemed it couldn't find my grub menu...
