Hello, The machine is an Sun Ultra 24, I'm trying to replace the original SATA boot disk (250G) with a a mirror of 2 250GB slices on 2 1TB disks. I inserted the first new disk which I labeled, sliced, attached to rpool, resilvered and finally installed grub on it.I then stop the machine, boot it and go the bios to select the new drive and boot from it. It works and I doubled check once booted that it actually booted from the new disk using the "prtconf -v|sed -n '/bootpath/,/value/p'" stanza. Next step in my plan was to remove the original boot disk, insert the second new 1TB disk and repeat the steps above so that I would end up with intended rpool consisting of a mirror of the 2 slices 0 on the 2 new disks. So I remove the original disk and reboot. Grub takes control, it starts to boot but stops after printing the line "Hostname: xxx". Normally the line after that is something like "Reading ZFS configuration". With the -v boot option, the last message printed is pseudo-device: srn0 srn0 is /pseudo/s...@0 When I put back the original boot disk, it completes the boot again. So it seems the system it actually booting fine from both disks, but only as long as the original disk is still there. Does this ring a bell ? Thanks for any hint...
Have you tried doing a zpool detach on the disk you want to remove before rebooting it?
I've seen similar problems at boot with missing root mirrors (in my case, the external device was a USB drive that I was planning to use for an offsite copy) - if that device was turned off, I was unable to boot. If it was on, able to boot. If I detached it, it didn't matter the state.
It may be that the uninitialized data on that new device is confusing things. _______________________________________________ indiana-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/indiana-discuss
