But is there any way to recreate bucket index for existing bucket?

Will the new index become sharded? 2016-06-14 13:18 GMT+03:00 Ansgar Jazdzewski <a.jazdzewski@xxxxxxxxxxxxxx>: > Hi, > > your cluster will be in warning state if you disable scrubbing, and > you relay need it in case of some data loss > > cheers, > Ansgar > > 2016-06-14 11:05 GMT+02:00 Wido den Hollander <wido@xxxxxxxx>: >> >>> Op 14 juni 2016 om 11:00 schreef Василий Ангапов <angapov@xxxxxxxxx>: >>> >>> >>> Is it a good idea to disable scrub and deep-scrub for bucket.index >>> pool?
