Hello
I have a 1.2.2 cluster of 6 nodes with several indexes configured with 2 to
4 replicas.
I'm trying to perform a snapshot but it completes only partially with
failures like this:
CreateSnapshotResponse[snapshotInfo=SnapshotInfo[name=2014-08-11-16-31-04,
state=PARTIAL,reason=,indices=Object[][{my\_idx3,my\_idx2}],
startTime=1407774870154,endTime=1407775114709,totalShards=17,
successfulShards=14,
shardFailures=Object[][{
[my\_idx2][4] failed, reason [IndexShardSnapshotFailedException[[my\_idx2][4]
Failed to perform snapshot (index files)]; nested: FileNotFoundException[
/home/shared\_dir/indices/my\_idx2/4/\_\_0 (No such file or directory)]; ],
[my\_idx2][3] failed, reason [IndexShardSnapshotFailedException[[my\_idx2][3]
Failed to perform snapshot (index files)]; nested: FileNotFoundException[
/home/shared\_dir/indices/my\_idx2/3/\_\_0 (No such file or directory)]; ],
[my\_idx3][0] failed, reason [IndexShardSnapshotFailedException[[my\_idx3][0]
Failed to perform snapshot (index files)]; nested: FileNotFoundException[
/home/shared\_dir/indices/my\_idx3/0/\_\_0 (No such file or directory)]; ]}]],
headers=,remoteAddress=inet[masternode/redacted:9300]]
I used CheckIndex to verify that those shards on all nodes do not have any
problems.
What might be the reason for that?

I upgraded to 1.3.1 and one of the indexes seems to backup ok now, though
the other one is still giving the error.

Well the backup is failing again on the index which was "fixed" after
upgrade.
Any idea how to debug this?
