Issues With DSR Upgrade With Zones (6616788)

Disk space reallocation (DSR) upgrade with zones fails if zones are installed in the /opt directory. Upgrade might fail during the restoration of the DSR archive. In some cases, the upgrade might be successful, but the system cannot be rebooted.

Workaround: Ensure that the root file system is not 100% full before upgrade. Remove some files before upgrade so that the root slice is less than 90% full.
