Description AndyT 2014-06-27 22:53:57 UTC
I am trying to rsync Solaris non-global zone from the global running the following command (from a

rsync -aSzx --del --ignore-errors --stats \
--exclude "sc-gis03/root/proc/*" \
--exclude "sc-gis03/root/var/run/*" \
--exclude "sc-gis03/root/system/contract/process/*" \
boi-blade02:/zones/sc-gis03 /zones

where `sc-gis03' is a running Solaris zone to be copied.

The problem I run into is this.  sc-gis03 has two NFS mounts.  The mountpoints are /docrep01 and
/backup01.  From rsync perspective, they appear as:

Since the two entries above are mountpoints, rsync does not have access to them, and returns the
following errors:

rsync: readlink_stat("/zones/sc-gis03/root/docrep01") failed: Not owner (1)
rsync: readlink_stat("/zones/sc-gis03/root/backup01") failed: Not owner (1)

This is fine, nothing can be done about it.  What seems to be wrong is that rsync deletes these
directories in the destination, as can be seen from a verbose run:

deleting sc-gis03/root/docrep01/
deleting sc-gis03/root/backup01/

IMHO, if rsync cannot stat a file because it does not have permissions to do so, it should just
leave it alone.  In case you are wondering, my script captures those `readlink_stat' errors, and
creates the directories after rsync exits, so next time the whole cycle is repeated.
