In a COW filesystem such as ZFS, it will sometimes be necessary to
return ENOSPC in cases such as chmod(2) which previously did not.
This is because there could be a snapshot, so "overwriting" some
information actually requires a net increase in space used.
That said, we may be generating this ENOSPC in cases where it is not
strictly necessary (eg, when there are no snapshots). We're working
on some of these cases. Can you show us the output of 'zfs list' when
the ENOSPC occurs?
Is there a bug id for this?
Can you search for ENOSPC in solaris/kernel/zfs? (That's
product/category/subcat. I don't know how the external bug interface works.)
Or check out 6362156 and 6453407.
