When trying to deploy your Vespa application and index your documents, you could receive the following error :
feed: got status 507 ({"pathId":"/document/v1/mynamespace/music/docid/hardwired-to-self-destruct","id":"id:mynamespace:music::hardwired-to-self-destruct","message":"[UNKNOWN(251009) @ tcp/a9a1e3304702:19112/default]: ReturnCode(NO_SPACE, External feed is blocked due to resource exhaustion: in content cluster 'music': disk on node 0 [a9a1e3304702] is 93.9% full (the configured limit is 75.0%). See https://docs.vespa.ai/en/operations/feed-block.html) "}) for put id:mynamespace:music::hardwired-to-self-destruct: not retryable
This is because the disk space is almost full (in this case 93.9%). When the nodes reach a certain limit, the nodes block external write operations.
By default Vespa sets it’s disk space limit at 0.75 (75%). You can increase it by adding the following lines to the ‘services.xml’ file in your Vespa application package, more precisely inside the ‘<content>’ tag :
<tuning>
<resource-limits>
<disk>0.98</disk>
</resource-limits>
</tuning>
This sets the disk limt to 98%.
This was just a quick fix, the most recommended method is to create a new node in the cluster.
