For quite some time I'm bitten by the fact that on my laptop (currently
running self-built snv_147) zpool status rpool and format disagree about
the device name of the root disk:
r...@masaya 14> zpool status rpool
pool: rpool
state: ONLINE
status: The pool is formatted using an older on-disk format. The pool can
still be used, but some features are unavailable.
action: Upgrade the pool using 'zpool upgrade'. Once this is done, the
pool will no longer be accessible on older software versions.
scan: none requested
config:

Specify disk (enter its number):
zpool status thinks rpool is on c1t0d0s3, while format (and the kernel)
correctly believe it's c11t0d0(s3) instead.
This has the unfortunate consequence that beadm activate<newbe> fails
in a quite non-obvious way.
Running it under truss, I find that it invokes installgrub, which
fails. The manual equivalent is
r...@masaya 266 # installgrub /a/boot/grub/stage1 /a/boot/grub/stage2
/dev/rdsk/c1t0d0s3
cannot read MBR on /dev/rdsk/c1t0d0p0
open: No such file or directory
r...@masaya 267 # installgrub /a/boot/grub/stage1 /a/boot/grub/stage2
/dev/rdsk/c11t0d0s3
stage1 written to partition 0 sector 0 (abs 16065)
stage2 written to partition 0, 273 sectors starting at 50 (abs 16115)
For the time being, I'm working around this by replacing installgrub by
a script, but obviously this shouldn't happen and the problem isn't easy
to find.
I thought I'd seen a zfs CR for this, but cannot find it right now,
especially with search on bugs.opensolaris.org being only partially
functional.
Any suggestions?
Thanks.
Rainer
