cieloxlg commented 5 years ago

Note: under ubuntu the initdb command is not provided in the path. You should updated the exported PATH env variable or provide the --pg-bin-path command line option to the stolon-keeper command.

try: add --pg-bin-path /you/postgresql/bin/path to the command ./stolon-keeper

willzhang commented 5 years ago

i config --pg-bin-path /usr/pgsql-11/bin,but here still have problem

From the above log, It looks you stopped the Sentinel. Do you have it running ?

viggy28 commented 5 years ago

@dineshba that helps.

Perhaps the documentation here can be improved. https://github.com/sorintlab/stolon/blob/master/doc/simplecluster.md

When you try to start sentinel first time, it complains that there is no keepers registered (makes sense)

Then you start the keeper, it errors our keeper data is not available, waiting for it to appear. At that point, start the sentinel.

dineshba commented 5 years ago

Hi @viggy28, no keepers registered in sentinel is more of a warning. Once we start the keeper, sentinel will be able to discover the keeper.

Note: There is no particular order for starting the proxy,sentinel,keeper

@willzhang and @viggy28 Can we close this issue?

viggy28 commented 5 years ago

Hi @dineshba , thanks for the response. No issues from my side in closing this issue.

ps: I am not the creator of this issue.
