[zfs-discuss] Q: T2000: raidctl vs. zpool status
Hi all, IHACWHAC (I have a colleague who has a customer - hello, if you''re listening :-) who''s trying to build and test a scenario where he can salvage the data off the (internal ?) disks of a T2000 in case the sysboard and with it the on-board raid controller dies. If I understood correctly, he replaces the motherboard, does some magic to get the raid config back, but even when raidctl says "I''m fine", zpool complains that it cannot open one of the replicas: # raidctl RAID Volume RAID RAID Disk Volume Type Status Disk Status ------------------------------------------------------ c0t0d0 IM OK c0t0d0 OK c0t1d0 OK c0t2d0 IM OK c0t2d0 OK c0t3d0 OK # zpool status -x pool: dpool state: FAULTED status: One or more devices could not be opened. There are insufficient replicas for the pool to continue functioning. action: Attach the missing device and online it using ''zpool online''. see: http://www.sun.com/msg/ZFS-8000-D3 scrub: none requested config: NAME STATE READ WRITE CKSUM dpool UNAVAIL 0 0 0 insufficient replicas c0t2d0 UNAVAIL 0 0 0 cannot open # what the customer does to achieve this is documented in the attachment (sorry about the German comments, but I thought translating them would have been a bit much to ask). TIA for any comments, etc. Michael -- Michael Schuster (+49 89) 46008-2974 / x62974 visit the online support center: http://www.sun.com/osc/ Recursion, n.: see ''Recursion'' -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...

Just FYI: cust removed /etc/zfs/zpool.cache and rebooted. using "zpool import", he was then able to import the pool anew. We''re still interested in your opinion on this - so pls. keep those emails coming :-) TIA Michael PS: pls keep Steffen on your replies as well, he''s not on the list.
