Hi,

We have a cluster where the master runs TokuMX 2.0.0, and one of the slaves runs TokuMX 2.0.1 (probably not a good practice…)

I connected to the shell of the slave, and it seems the master crashed just around this time:

Not sure if this is related to the different versions, but anyway looks like something you’d want to investigate.

Thanks,

Hi Zoharby,

Good practices point that master / slaves should be in the same version of TokuMX.

Could you also upload logs from master and secondary ?

Thanks
