zrep sync fails after solaris 11 upgrade from SRU60 to SRU68 #207

Open normans2 opened 3 weeks ago

normans2 commented 3 weeks ago

zrep -S all was running OK via crontab and stopped following Solaris OS upgrade from SRU60 to SRU68. ZREP_VERSION=2.0.2

Cleared out zrep data and replicated datasets on secondary then re-initialized parent dataset which worked OK and I can see snapshots on both sides.

Hm. I'm afraid I cant test this myself, as I no longer run solaris. Best to ask help from forums. seems like they broke compatibility in some way.

Either, this is a bug, or this is deliberate feature transition. If it isnt just a bug, and if you find a definitive answer and solution, please let me know
