Subject Re: Kudu tablet server generated new uuid and did not disappeared from active configs
Date Wed, 17 Oct 2018 18:23:15 GMT
How many tservers did you reformat? If more than one, it's important
to do the reformatting one at a time, so that degraded tablets can
rereplicate elsewhere. Based on the ksck results it looks like maybe
you reformatted two tservers at the same time? If not, perhaps tablet
c0c16a68fd2f4174b03f1accbc9aca22 was degraded prior to the reformat.

What version of Kudu is this? Can you provide the full ksck output?
