I’m running my dGraph (v1.0.11) cluster in docker containers on three servers - 3 alphas, 3 zeros (8xcore, 64GB RAM).
Each servers has two ssd disks - one 25 GB and 300 GB.
This morning one of alphas stops to response (may be all cluster). When I checked logs, I found this line as last one in logs:
log: exiting because of error: write /tmp/dgraph.3.root.log.INFO.20190124-015534.1: no space left on device
Docker logs are stored at smaller one of disks.
When I removed old container (also erased logs) and started new one, everything starts to work.
Is it possible that alpha stop works when there is no disk space for logs? Is this bug?
