I am trying to figure out an effective way to recover a host with
zones. The zone is whole-root zone in Sol10 05/09.

root(a)host1 # cat excludelist.txt
/tank
/patches
/zones/db1/root/tank/home (zfs)
/zones/db1/root/app (ufs)
/zones/db1/root/patches (lofs)

While zone db1 is running, I take a flash archive:

root(a)host1 # flarcreate -n host1 -X /var/tmp/excludelist.txt /var/tmp/
host1-zones-noapps.flar &

Jumpstart the host1, db1 does not boot automatically, and here is the
error.

root(a)host1 # zoneadm -z db1 boot
zoneadm: zone 'db1': could not stat /zones/db1/root/sbin/init: No such
file or directory

I checked the running zone, there is no /zones/db1/root/sbin/init.


So I step back to flash archive only OS, back up zone.

root(a)host1 # cat excludelist.txt
/tank
/patches
/zones

root(a)host1 # flarcreate -n host1 -X /var/tmp/excludelist.txt /var/tmp/
host1-zones-noapps.flar &

Halt the zone,
root(a)host1 # tar cf /var/tmp/zones-db1-halted.tar /zones/db1

Jumpstart the host, restore the zone and boot it. It works

If I let zone run while make a tar of the zone path, it throws out
some messages. But the zone boots after restoring the tar file.


What is your experience with DR strategy?

On Indiana backup is something like this:
foobar# zlogin foo init 5
foobar# zoneadm -z foo detach
foobar# zfs snapshot -r tank/var/zones/foo(a)backup
foobar# zoneadm -z foo attach
foobar# zoneadm -z foo boot
foobar# zfs send -R tank/var/zones/foo(a)backup | 7z a -si -bd /mnt/foo.snap.7z

Recovery is something like:
snafu# 7z x -bd -so /mnt/foo.snap.7z | zfs receive -u -d tank
snafu# zfs set mountpoint=/var/opt/zones/foo tank/var/zones/foo
snafu# zfs mount tank/var/zones/foo
snafu# mount -F zfs tank/var/zones/foo/ROOT/zbe /var/opt/zones/foo/root
snafu# zonecfg -z foo create -a /var/opt/zones/foo
snafu# zoneadm -z foo attach
snafu# zoneadm -z foo boot

"7z"?????

I think that's the first ever Solaris command with a leading numeric
character!

90% of our zones are on zfs datasets, to restore or move a zone I use
zfs send/recv

zonepool/zone1 /zones/zone1

zfs sanpshot zonepool/zone1(a)move

zfs send zonepool/zone1(a)move | ssh targethost zfs recv -F newzonepool/
zone1

zfs set mountpoint=/zones/zone1 newzonepool/zone1

Then copy over the /etc/zones/zones.xml file along with the correct
entry in the index file in /etc/zones and modify the IP address

Then I am able to boot this zone on the target server.
