Hi, I'm sorry to bug the OpenSolaris for a question that pertains to
S10U8, but I am really stuck.
I am doing a zoneadm clone -m copy, and I do not want a new ZFS
dataset even though my zonepath is on a ZFS filesystem, for
performance reasons particular to how I am using my zones.
Unfortunately, zoneadm clone just ignores the -m copy, and makes me
a new ZFS filesystem anyway; and by the speed with which it finished,
it certainly is a snapshot operation underneath.
I have tested with making the source zone on a separate UFS, have
pre-made a dirname under my ZFS filesystem as the zonepath, nothing
works. I always get a new ZFS filesystem. I see that zoneadm install
has an -x nodataset switch, I need this for zone clone as well. I
have not seen this filed as a bug against S10, is there a work-around
to get the behavior I want?
You can probably work around this by replacing
zoneadm -z newzone clone -m copy master
With:
# do this once
zoneadm -z master halt
zoneadm -z master detach
cd $master_zonepath
tar cf $dir/master.tar .
zoneadm -z master attach
# do this for each zone to create
mkdir $newzone_zonepath
cd $newzone_zonepath
tar xpf $dir/master.tar
zonecfg -z newzone create -a $newzone_zonepath
zoneadm -z newzone attach
zoneadm -z newzone boot -s
zlogin newzone sys-unconfig
zoneadm -z newzone boot
zlogin -C newzone
You could certainly put the sys-unconfig before detaching the master
zone and could put other steps before the multi-user boot of newzone
to get a valid /etc/sysidcfg in place, thereby skipping the zlogin -C
and interaction with sysidconfig.
This is sort of a big deal for our application. We use labeled zones,
a file move within a filesystem has a different performance profile
than a move from one filesystem to another filesystem, even within one
ZFS pool. We are doing tens of thousands of move per minute.
