             Summary: Backup failing with solr 7.7.2 java.io.IOException: Interrupted system call
                 Key: SOLR-14845
                 URL: https://issues.apache.org/jira/browse/SOLR-14845
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
          Components: Backup/Restore
    Affects Versions: 7.2.2
            Reporter: Jeff


I have a 12 node solrcloud cluster with 48 shards.
800GB on each node.
7.3 million docs and around 98 GB per shard.
 
 
When I issue the backup command it runs for several hours and produces most of the backup but fails on some shards.
 
Command issued
curl -XPOST 'http://xx.xxx.xxx.xxx:8983/solr/admin/collections?action=BACKUP&name=prod1&collection=PROD&location=/mnt/prodstorage/backup&async=111113&wt=xml'
 
    "Response":"TaskId: 1111127375391376590965 webapp=null path=/admin/cores params={core=PROD_shard8_1_replica_n156&async=1111127375391376590965&qt=/admin/cores&name=shard8_1&action=BACKUPCORE&location=file:///mnt/prodstorage/backup/prod1&wt=javabin&version=2} status=0 QTime=0"},
  "1111127375391376904569":{
    "responseHeader":{
      "status":0,
      "QTime":0},
    "STATUS":"failed",
    "Response":"Failed to backup core=PROD_shard19_1_replica_n263 because java.io.IOException: Interrupted system call"},
  "status":{
    "state":"failed",    "msg":"found [111112] in failed tasks"}}
 
 
Can I lengthen the timeout? Manaully backup?
