This is a consolidation effort, avoiding usage
of naked strings in codebase. Whenever possible
use constants which can be repurposed elsewhere.
This also fixes `goconst ./...` reported issues.
There was an error in how we validated disk formats,
if one of the disk was formatted and was formatted with
FS would cause confusion and object layer would never
initialize essentially go into an infinite loop.
Validate pre-emptively and also check for FS format
properly.
This is needed to validate if the `format.json` indeed exists
when a fresh node is brought online.
This wrapped implementation also connects to the remote node
by attempting a re-login. Subsequently after a successful
connect `format.json` is validated as well.
Fixes#3207
Ref #3229
After review with @abperiasamy we decided to remove all the unnecessary options
- MINIO_BROWSER (Implemented as a security feature but now deemed obsolete
since even if blocking access to MINIO_BROWSER, s3 API port is open)
- MINIO_CACHE_EXPIRY (Defaults to 72h)
- MINIO_MAXCONN (No one used this option and we don't test this)
- MINIO_ENABLE_FSMETA (Enable FSMETA all the time)
Remove --ignore-disks option - this option was implemented when XL layer
would initialize the backend disks and heal them automatically to disallow
XL accidentally using the root partition itself this option was introduced.
This behavior has been changed XL no longer automatically initializes
`format.json` a HEAL is controlled activity, so ignore-disks is not
useful anymore. This change also addresses the problems of our documentation
going forward and keeps things simple. This patch brings in reduction of
options and defaulting them to a valid known inputs. This patch also
serves as a guideline of limiting many ways to do the same thing.
For command line arguments we are currently following
- <node-1>:/path ... <node-n>:/path
This patch changes this to
- http://<node-1>/path ... http://<node-n>/path
These messages based on our prep stage during XL
and prints more informative message regarding
drive information.
This change also does a much needed refactoring.
