sbin/newfs_hammer: Fix "less than 10GB" error message on newfs
- Add "(for the size of Volume 0)". Trying to make >10GB hammer
with multiple less-than-10GB-disks results the same error.
- This message appears whenever the root volume (the volume #0
where layer1/2 are stored by newfs) has less than 10GB space
in zone2/volume0 address space. It doesn't matter if the total
size of physical disks are large enough or not.
# /sbin/newfs_hammer -L TEST /dev/da8 /dev/da9 /dev/da10 /dev/da11
Volume 0 DEVICE /dev/da8 size 7.22GB
Volume 1 DEVICE /dev/da9 size 28.88GB
Volume 2 DEVICE /dev/da10 size 7.20GB
Volume 3 DEVICE /dev/da11 size 1.86GB
initialize freemap volume 0
newfs_hammer: Cannot create a HAMMER filesystem less than 10GB unless you use -f
(for the size of Volume 0). HAMMER filesystems less than 50GB are not recommended.
- It's probably better if newfs_hammer could fail with this
error message without writing (write(2)) to ondisk layer1/2
structure. The layer1/2 have already been written to the root
volume by the time the process is aborted. Also note that this
is the only newfs_hammer sanity check failure that affect ondisk.
All the other checks abort before ondisk formatting starts.
