I have a couple of questions regarding index corruptions. 1) Has anyone using Solr in a production environment ever experienced an index corruption? If so, how frequently do they occur?
I once had all slaves complain about a missing file in the index. The master never had a problem. The problem went away at the next snapshot. Is the "cp-lr" in snapshot really guaranteed to be atomic? Or is it just fast, and unlikely to be interrupted? This has only occurred once over the last 5 months. 2) It seems like the CollectionDistribution setup would be a good way to
put in place a recovery plan for (or at least have some viable backups of) the index. However, I have a small concern that if the index gets corrupted on the master server, the corruption would propagate down to the slave servers as well. Is this concern unfounded?
I would expect this to be true. Also, each of the
snapshots taken by snapshooter are viable full indexes, correct? If so, that means I'd have a backup of the index each and every time a commit (or optimize for that matter) is done, which would be awesome.
That's my understanding. Tom
