I would hope so. Just trying to get some confirmation from someone with
production experience. 

 

Thanks for your reply

Subject: Re: Multiple JBOD data directory

 

Though, I am a newbie bust just had a thought regarding your question 'How
will it handle requests for data which unavailable?', wouldn't the data be
served in that case from other nodes where it has been replicated?

 

Regards,

Shahab

Hello, 

 

We're thinking about using multiple data directories each with its own disk
and are currently testing this against a RAID0 config.

 

I've seen that there is failure handling with multiple JBOD.

 

e.g. 

We have two data directories mounted to separate drives

/disk1

/disk2

One of the drives fails 

 

Will Cassandra continue to work?

How will it handle requests for data which unavailable?

If I want to add an additional drive what is the best way to go about
redistributing the data? 

 

Thanks,

Chris
