Re: Incremental repairs after a migration?

you can get away with loading from only one node if you're positive all
data is consistent. A repair prior to loading should be enough, but if that
doesn't work just load from all nodes.

If the previous cluster had 3 nodes with RF=3 (like the new one), do I
really need to sstableload all 3 nodes?

I assumed that sstableloading one node would be enough to populate all
data on all 3 nodes.

If everything goes smoothly the next incremental should cut it, but a full
repair post load is probably a good idea anyway. Make sure you sstableload
every sstable from every node if you want to keep consistency.

Incremental repairs after a migration?

[Brice Figureau]

Hi,

I'm running 3.0.15 in a 3 nodes cluster with RF=3.
This is a brand new cluster, on which I plan to migrate data from
another 3.0.15 cluster running in another environments (taking a
snapshot and sstableloader those sstables to the new cluster).

The original cluster had been migrated to incremental repairs when I
moved it to 3.0.

Should I need to perform again a full repair after migrating or is
running daily incremental enough?

Thanks!
