Hi -
I think it depends on how you define "read only" - read-only usually
implies that you cannot alter the data on a filesystem. I don't
know whether it should apply to the underlying geometry of the filesystem.
Since the growfs operation leaves the data on the filesystem unchanged,
I don't see any problem with xfs_growfs on a read-only fs.
I'm also fairly certain that this matches Irix behavior, but I'll have
to check.
