Solr Replication: How to restore data from last snapshot
Hi,
I have followed Solr set up ReplicationHandler for index replication to slave.
Do anyone know how to restore corrupted index from snapshot in master, and force replication of the restored index to slave?
Thanks,
Osborn

Thread Hijacking on Mailing Lists
When starting a new discussion on a mailing list, please do not reply to
an existing message, instead start a fresh email. Even if you change the
subject line of your email, other mail headers still track which thread
you replied to and your question is "hidden" in that thread and gets less
attention. It makes following discussions in the mailing list archives
particularly difficult.

What happen if it is multiple core?
Thanks

if it is a single core you will have to restart the master

Thanks. But I have following use cases:
1) Master index is corrupted, but it didn't replicate to slave servers.
- In this case, I only need to restore to last snapshot.
2) Master index is corrupted, and it has replicated to slave servers.
- In this case, I need to restore to last snapshot, and make sure slave servers replicate the restored index from index server as well.
Assuming both cases are in production environment, and I cannot shutdown the master and slave servers.
Is there any rest API call or something else I can do without manually using linux command and restart?
Thanks,
Osborn

If your master index is corrupt and it hasn't been replicated out, you
should be able to shut down the server and remove the corrupted index
files. Then copy the replicated index back onto the master and start
everything back up.
As far as I know, the indexes on the replicated slaves are exactly
what you'd have on the master, so this method should work.
