Timothy Potter created SOLR-12523:
-------------------------------------
Summary: Collection backup fails whether the location + name
directory exists or not exists.
Key: SOLR-12523
URL: https://issues.apache.org/jira/browse/SOLR-12523
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: Backup/Restore
Affects Versions: 7.3.1
Reporter: Timothy Potter
So I have a large collection with 4 shards across 2 nodes. When I try to back
it up with:
{code}
curl
"http://localhost:8984/solr/admin/collections?action=BACKUP&name=sigs&collection=foo_signals&async=5&location=backups";
{code}
I either get:
{code}
"5170256188349065":{
"responseHeader":{
"status":0,
"QTime":0},
"STATUS":"failed",
"Response":"Failed to backup core=foo_signals_shard1_replica_n2 because
org.apache.solr.common.SolrException: Directory to contain snapshots doesn't
exist: file:///vol1/cloud84/backups/sigs"},
"5170256187999044":{
"responseHeader":{
"status":0,
"QTime":0},
"STATUS":"failed",
"Response":"Failed to backup core=foo_signals_shard3_replica_n10 because
org.apache.solr.common.SolrException: Directory to contain snapshots doesn't
exist: file:///vol1/cloud84/backups/sigs"},
{code}
or if I create the directory, then I get:
{code}
{
"responseHeader":{
"status":0,
"QTime":2},
"Operation backup caused
exception:":"org.apache.solr.common.SolrException:org.apache.solr.common.SolrException:
The backup directory already exists: file:///vol1/cloud84/backups/sigs/",
"exception":{
"msg":"The backup directory already exists:
file:///vol1/cloud84/backups/sigs/",
"rspCode":400},
"status":{
"state":"failed",
"msg":"found [2] in failed tasks"}}
{code}
I'm thinking this has to do with having 2 cores from the same collection on the
same node but I can't get a collection with 1 shard on each node to work either:
{code}
"ec2-52-90-245-38.compute-1.amazonaws.com:8984_solr":"org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException:Error
from server at http://ec2-52-90-245-38.compute-1.amazonaws.com:8984/solr:
Failed to backup core=system_jobs_history_shard2_replica_n6 because
org.apache.solr.common.SolrException: Directory to contain snapshots doesn't
exist: file:///vol1/cloud84/backups/ugh1"}
{code}
What's weird is that replica (system_jobs_history_shard2_replica_n6) is not
even on the ec2-52-90-245-38.compute-1.amazonaws.com node! It lives on a
different node.
