Hi,

I finally got around to testing it on a regular (raw hardware) system,
but there it works without problem.
It also works on a root UFS disk in a bhyve jail.

But I'm not able to get it to go on a VM in a VMware enviroment...

System GENERIC:
FreeBSD some.server.nl 10.1-RELEASE-p9 FreeBSD 10.1-RELEASE-p9 #0: Tue
Apr  7 01:09:46 UTC 2015

Disk device:
da0 at mpt0 bus 0 scbus2 target 1 lun 0
da0: <VMware Virtual disk 1.0> Fixed Direct Access SCSI-2 device
da0: 320.000MB/s transfers (160.000MHz, offset 127, 16bit)
da0: Command Queueing enabled
da0: 409600MB (838860800 512 byte sectors: 255H 63S/T 52216C)

% mount
/dev/da0p2 on / (ufs, local, journaled soft-updates)

When running growfs, in multi-user mode, everything seems to freeze when
it nees diskio, and I get the feeling that the growfs process is halted
on the FS-suspend.
I've let it sit for about an hour, but nothing changed.

Hard resetting recovers the system with no problems what so ever.

Any suggestions to get this done without going to single-user would be
more than appriciated.

Thanx,
--WjW
