Issue : Prometheus Restarting with below error ``` level=error ts=2020-04-27T00:09:41.712Z caller=main.go:740 err="opening storage failed: block dir: \"/prometheus/01DZCNZNP4SB2VVD8EY1V7HYSJ\": open /prometheus/01DZCNZNP4SB2VVD8EY1V7HYSJ/meta.json: no such file or directory" ```
Observation : 1. Checked the Datablocks & findout we lost around 300GB of datablocks. 2. We have one disk space alert , Assuming that disk got full before invoking this issue and something trigger the deleting on old datablock the disk got free. 3. Moved the corrupted datablocks to /tmp directory so promethus start working but old metrics are lost & After start its using high resource 2X CPU load & high Memory utilisation. Q1. Any Idea Why this error got triggered ? Q2. What is the Normal behaviour of Promethus if no disk space is available for storing the metrics ? Q3 . If its deleted automatically then any parameters are available to tweak this configurations ? -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
