In the testing mode, reformatting disks will fail because the healing
code will complain if one disk is in root mode. This commit will
automatically set all disks as non-root if MINIO_CI_CD is set.
Currently, when applying any dynamic config, the system reloads and
re-applies the config of all the dynamic sub-systems.
This PR refactors the code in such a way that changing config of a given
dynamic sub-system will work on only that sub-system.
An onlineDisk means its a valid disk but it may be a
re-connected disk, this PR verifies that based on LastConn()
to only trigger MRF. Current code would again re-load the
disk 'format.json' which is not necessary and perhaps an
unnecessary call.
A potential side affect of this is closing perfectly online
disks and getting re-replaced by reloading 'format.json'.
This PR tries to avoid this situation by making sure MRF
is triggered but not reloading 'format.json' because of MRF.
The `LookupConfig` code was not using `GetWithDefault`, because of which
some of the config values were being returned as empty string, and calls
like `strconv.Atoi` and `time.ParseDuration` on these were failing.
If the policy fails MinIO's minimum threshold for a valid policy,
they'll still (correctly) fail, but policies with a : (and probably a
/) should be allowed since they work with standard MC/MinIO
Console interactions.
This creates the files as policy_IDX.json instead of <name>.json
to avoid any issues with the name + Kubernetes ConfigMaps since
ConfigMap keys must be: [-._a-zA-Z0-9]+
Only the first `listAndHeal` would ever be able to write on errCh, blocking all others infinitely.
Instead read all errors but return the first non-nil, if any.
The intention appears to be that this should cancel on any error,
so that part is kept.
Regression from #13990
When more than one gateway reads and writes from the same mount point
and there is a load balancer pointing to those gateways. Each gateway
will try to create its own temporary append file but fails to clear it later
when not needed.
This commit creates a routine that checks all upload IDs saved in
multipart directory and remove any stale entry with the same upload id
in the memory and in the temporary background append folder as well.
Enabled with `mc admin config set alias/ api gzip_objects=on`
Standard filtering applies (1K response minimum, not compressed content
type, not range request, gzip accepted by client).
The current code considers a pool with all root disks to be as part
of a testing environment even if there are other pools with mounted
disks. This will result to illegitimate writing in root disks.
Fix this by simplifing the logic: require MINIO_CI_CD in order to skip
root disk check.
