Hi Matty,
great feature, but unfortunately it does not work as expected:
You’re able to add the free space by the expand command but unable to label the disk while it’s in use (e.g. mounted partitions) – although NOINUSE_CHECK is set.

Any suggestions here?

Do you know any progress details about “zpool autoexpand property (PSARC/2008/353)”?

Thanks, Thomas

hey Matty —- this may not always the desired behavior – lets say if the LUN size is hovering at 990G and the SAN engineer expands it to >1T – then if opensolaris automagically converts the label from VTOC to EFI (assuming the earlier label is VTOC) — this may corrupt the data on the LUN

agreed?
