After an upgrade of our small cluster (two indexers, one search head, RF=SF=2) to 6.6.0, 5 indexes are marked as not searchable.
There are 0 "fix up" type tasks. I have tried gracefully restarting both indexers again (one at a time) and no luck there. Any help is appreciated. Thanks.
Strangely there were some buckets without PEER information, which appears that the cluster master has some buckets information that its peers do not have.
Then ran remove_all which worked around the issue :
