Fragments ?

[Florian Rißner]

Hello,

some questions about usage of fragmentation:

1. is it possible to configure where a fragment may is stored on disk?
e.g. am I able to configure that fragment 1 is stored on localdisk sda1 and fragment 2 is stored on localdisk sdb1

2. what happens if another storage-space is added to a node?
e.g. sdc1 is added to a node; a new fragment 3 is configured to store on this disk

2a. what happens to this node? will the data become reorganized and spread over all 3 fragments?

2b. what happens to cluster if fragmentation is configured different on different nodes?
e.g. node 2 and node 3 are configured with fragment 1 and 2; node 1 is configured with frament 1,2 and 3

is there any additional spec to "MySQL Cluster Administrator Guide" ?
i'm looking for some information particularly concerning the fragmentation problem


Sincerely Yours,

P.S.: any experiences with an API-node on Windows-Server and DB-Nodes on linux-servers?
