Hi.
I am trying to move the root volume from an existing svm mirror to a zfs
root. The machine is a Sun V880 (SPARC) running nv_96, with OBP version
4.22.34 which is AFAICT the latest.
The svm mirror was constructed as follows
/
d4 m 18GB d14
d14 s 35GB c1t0d0s0
d24 s 35GB c1t1d0s0
swap
d3 m 16GB d13
d13 s 16GB c1t0d0s3
d13 s 16GB c1t1d0s3
/var
d5 m 8.0GB d15
d15 s 16GB c1t0d0s1
d25 s 16GB c1t1d0s1
I removed c1t1d0 from the mirror:
# metadetach d4 d24
# metaclear d24
# metadetach d3 d23
# metaclear d23
# metadetach d5 d25
# metaclear s25
then removed the metadb from c1d1d0s7
# metadb -d c1t1d0s7
Resized s0 on c1t1d0 to include the whole disc and relabelled with an
SMI label.
Created the zfs root pool:
# zpool create rpool c1t1d0s0
Created new BE:
# lucreate -c Sol11_b96 -n Sol11_b96_zfs -p rpool
This ran fine, so I activated the new BE and rebooted
# luactivate Sol11_b96_zfs
# init 6
The system then panicked during the reboot with:
Rebooting with command: boot

syncing file systems... done
skipping system dump - no dump device configured
rebooting...
It then cycles the reboot and panic until I pull the disc and reboot
continues from the original boot disc.
Any ideas why mounting root on zfs is apparently not supported?
