Hi,
We updated our ~90 node cluster from 1.2.1 to 1.3.5 (to try to fix some
performance issues).
After stopping and starting all nodes the new cluster came up green, only
the indices are missing.
The lucene indices are still available on the disks of the data nodes, so I
am hoping I can get them back in elasticsearch.
How could this be done?
Regards Jasper
