Nitish Tiwari	197af49c99	Fix healthcheck handler to verify gateway backend liveness (#6218) ... Fixes #6217	2018-07-31 10:55:34 -07:00
Harshavardhana	157ed65c35	Fix healthcheck handler to check errors in local disks only (#6184) ... Healthcheck handler in current implementation was performing ListBuckets() to check for liveness of Minio service. ListBuckets() implementation on the other hand doesn't do quorum based listing and if one of the disks returned error, an I/O error it would be lead to kubernetes taking the minio pod down prematurely even if the disk is not local to that minio server. The reason is ListBuckets() call cannot be trusted to provide us the valid information that we need, Minio is a clustered application which is designed to handle disk failures. Error on one of the disks doesn't mean the pod should become fully non-operational. This PR attempts to fix this by only checking for alive disks which are local to each setup and also by simply performing a Stat() operation, if the Stat() returned error on all disks local to a particular server then we can let kubernetes safely take it down, until then we should be operational.	2018-07-23 12:21:25 -07:00

Nitish Tiwari	10b01ac836	Add healthcheck endpoints (#5543) ... This PR adds readiness and liveness endpoints to probe Minio server instance health. Endpoints can only be accessed without authentication and the paths are /minio/health/live and /minio/health/ready for liveness and readiness respectively. The new healthcheck liveness endpoint is used for Docker healthcheck now. Fixes #5357 Fixes #5514	2018-03-12 11:46:53 +05:30
