I have a Solaris 10 machine that I''ve been having an interesting time with today. (Live Upgrade didn''t work, stmsboot didn''t work, I managed to rebuild it with jumpstart at about the 10th attempt.) Anyway, it looks like one of my drives has had its label overwritten by fdisk, pool: disk00 id: 10866402904016234458 state: UNAVAIL status: One or more devices are missing from the system. action: The pool cannot be imported. Attach the missing devices and try again. see: http://www.sun.com/msg/ZFS-8000-6X config: disk00 UNAVAIL missing device c2t0d1 ONLINE Additional devices are known to be part of this pool, though their exact configuration cannot be determined. And if I look at format, I see the drives [it''s a 2530, btw] as 0. c1t0d0 <DEFAULT cyl 44381 alt 2 hd 255 sec 126> /pci at 0,0/pci10de,5d at d/pci1000,3150 at 0/sd at 0,0 4. c2t0d1 <SUN-LCSM100_S-0670-680.00GB> /pci at 0,0/pci10de,5d at e/pci1000,3150 at 0/sd at 0,1 So it looks like c1t0d0 (which is where I think the other half of the pool is) has been relabelled by fdisk and has an SMI label on it. Is there a way to reverse this, and if so, how? This is annoying, rather than critical: the system is out of service and I can reconstruct the data if necessary. Although knowing how to fix this would be generally useful in the future... Thanks, -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/
