Ah Thanks! I have fs(3) configured as follows: cpu% cat /dev/fs/ctl mirror arenas /dev/sdD0/arenas /dev/sdD1/arenas mirror isect /dev/sdD0/isect /dev/sdD1/isect mirror fscfg /dev/sdD0/fscfg /dev/sdD1/fscfg And my disks have been formatted and partitioned beforehand like this: cpu% lc sdD0 arenas ctl data fscfg isect plan9 raw cpu% lc sdD1 arenas ctl data fscfg isect plan9 raw Still if I know run cmp against the arena partition from the running system it says they differ, and ls says the same: cpu% lc -ld sdD* --rw-r----- S 0 bootes bootes 285779527168 Dec 5 03:37 arenas --rw-r----- S 0 bootes bootes 285777530368 Dec 5 03:37 arenas --rw-r----- S 0 bootes bootes 0 Dec 5 03:37 ctl --rw-r----- S 0 bootes bootes 0 Dec 5 03:37 ctl --rw-r----- S 0 bootes bootes 300069052416 Dec 5 03:37 data --rw-r----- S 0 bootes bootes 300069052416 Dec 5 03:37 data --rw-r----- S 0 bootes bootes 512 Dec 5 03:37 fscfg --rw-r----- S 0 bootes bootes 512 Dec 5 03:37 fscfg --rw-r----- S 0 bootes bootes 14288976384 Dec 5 03:37 isect --rw-r----- S 0 bootes bootes 14288876544 Dec 5 03:37 isect --rw-r----- S 0 bootes bootes 300068504064 Dec 5 03:37 plan9 --rw-r----- S 0 bootes bootes 300066407424 Dec 5 03:37 plan9 -lrw------- S 0 bootes bootes 0 Dec 5 03:37 raw -lrw------- S 0 bootes bootes 0 Dec 5 03:37 raw I cannot see the /dev/fs directory from my server terminal so I wonder if fs is even active? But if it is not I wonder how my venti tells me it is using /def/fs/arenas for storage? I guess that fs(3) is working properly otherwise it would not show the correct configuration on a simple bind. But then why do the disks differ and would it suffice to dd the contents of sdD0 to sdD1 using the live cd?
