Hi
Is there any good documentation regarding reprovisioning best
practices? man vmadm doesn't help much.
I reprovisioned a zone with delegated datasets mounted at
/var/openldap and /opt/local/etc/openldap and the zone ended up in a
failed state. Recovery was simple enough but some do's and dont's for
future reference would be handy. Should I have mounted the delegated
datasets at their default location and symlinked instead? Do I just
back my data up to a delegated dataset and copy it back after the
reprovision? How do the smart people do this?
That might have something to do with the mountpoints being under /var
and /opt, I've always mounted the delegated dataset in /data by doing #
zfs set mountpoint=/data and haven't seen issues when reprovisioning zones.
What kind of behavior you faced while reprovisioning?
Yes you could copy data over to a delegated dataset and copy back after
reprovisioning but I've found it easiest (and quickest in terms of
repvosioning, combined with tools such as Ansible for rebuilding new
instances) to just edit configuration files where possible, ie. with web
servers such as Apache or Nginx just pointing to /data/www/foobar for
web root.
Hope these will help a little bit.
