Hi all, We have a situation where some of our nodes have smaller disks and we would like to align all nodes by replacing the smaller disks to bigger ones without replacing nodes. We don't have enough space to put data on / disk and copy it back to the bigger disks so we would like to rebuild the nodes data from other replicas.
What do you think should be the procedure here? I'm guessing it should be something like this but I'm pretty sure it's not enough. 1. shutdown C* node and server. 2. replace disks + create the same vg lv etc. 3. start C* (Normally?) 4. nodetool repair/rebuild? *I think I might get some consistency issues for use cases relying on Quorum reads and writes for strong consistency. What do you say? Another question is (and I know it depends on many factors but I'd like to hear an experienced estimation): How much time would take to rebuild a 250G data node? Thanks in advance, Or. -- Or Sher
