Hi everyone，
My ES node has a index which has a shard with status UNASSIGNED, when i perform cluster reroute using this command:
curl -uuser:passwd -XPOST 'localhost:19200/_cluster/reroute?pretty' -d '{
"commands" : [ {
"allocate_stale_primary" : {
"index" : "pay-2018.03.25",
"shard" : 1,
"node" : "eNRHSjwxR8q2PVTK4_mrBA",
"accept_data_loss" : true
}
}
]
}'
there is an error occurs:
{
"state" : "INITIALIZING",
"primary" : true,
"node" : "eNRHSjwxR8q2PVTK4_mrBA",
"relocating_node" : null,
"shard" : 1,
"index" : "pay-2018.03.25",
"recovery_source" : {
"type" : "EXISTING_STORE"
},
"allocation_id" : {
"id" : "9Z6vKdQ_SoiqCSvTtUL9eA"
},
"unassigned_info" : {
"reason" : "ALLOCATION_FAILED",
"at" : "2018-03-29T01:27:38.432Z",
"failed_attempts" : 3,
"delayed" : false,
"details" : "failed recovery, failure RecoveryFailedException[[pay-2018.03.25][1]: Recovery failed on {node1}{eNRHSjwxR8q2PVTK4_mrBA}{2jHq-9pJQUWwi_jjI8Ua7A}{192.168.0.3}{192.168.0.3:9300}]; nested: IndexShardRecoveryException[failed to fetch index version after copying it over]; nested: CorruptIndexException[failed engine (reason: [corrupt file (source: [index])]) (resource=preexisting_corruption)]; nested: IOException[failed engine (reason: [corrupt file (source: [index])])]; nested: CorruptIndexException[checksum

"allocation_status" : "no_valid_shard_copy"
}
},
I know my index file has damaged , is there a way to repair it ? Or if i just don't need this corrupt file anymore, is there a way to recovery this index and put my cluster in yellow state.
PS:my ES cluster has only one node and i'm using ES 5.5.1 with SearchGuard
Thanks in advance!
