canonicalize the ENVs such that we can bring these ENVs
as part of the config values, as a subsequent change.
- fix location of per bucket usage to `.minio.sys/buckets/<bucket_name>/usage-cache.bin`
- fix location of the overall usage in `json` at `.minio.sys/buckets/.usage.json`
(avoid conflicts with a bucket named `usage.json` )
- fix location of the overall usage in `msgp` at `.minio.sys/buckets/.usage.bin`
(avoid conflicts with a bucket named `usage.bin`
As an optimization of the healing, HealObjects() avoid sending an
object to the background healing subsystem when the object is
present in all disks.
However, HealObjects() should have checked the scan type, if this
deep, always pass the object to the healing subsystem.
Currently, a tree walking, needed to a list objects in a specific
set quits listing as long as it finds no entries in a disk, which
is wrong.
This affected background healing, because the latter is using
tree walk directly. If one object does not exist in the first
disk for example, it will be seemed like the object does not
exist at all and no healing work is needed.
This commit fixes the behavior.
The staleness of a lock should be determined by
the quorum number of entries returning stale,
this allows for situations when locks are held
when nodes are down - we don't accidentally
clear locks unintentionally when they are valid
and correct.
Also lock maintenance should be run by all servers,
not one server, stale locks need to be run outside
the requirement for holding distributed locks.
Thanks @klauspost for reproducing this issue
Some AWS SDKs latently rely on this value some times
to calculate the right number of parts during a parallel
GetObject request, this is feature used along with
content-range - we should support this as well.
This commit fixes the env. variable in the
KMS guide used to specify the CA certificates
for the KES server.
Before the env. variable `MINIO_KMS_KES_CAPATH` has
been used - which works in non-containerized environments
due to how MinIO merges the config file and environment
variables. In containerized environments (e.g. docker)
this does not work and trying to specify `MINIO_KMS_KES_CAPATH`
instead of `MINIO_KMS_KES_CA_PATH` eventually leads to MinIO not
trusting the certificate presented by the kes server.

- avoid setting last heal activity when starting self-healing
This can be confusing to users thinking that the self healing
cycle was already performed.
- add info about the next background healing round
OperationTimedout error occurs when locking
timesout, trying to acquire a lock. This
error should be returned appropriately to
the client with http status "408" (request timedout)
This translation was broken, fix it.
Bulk delete API was using cleanupObjectsBulk() which calls posix
listing and delete API to remove objects internal files in the
backend (xl.json and parts) one by one.
Add DeletePrefixes in the storage API to remove the content
of a directory in a single call.
Also use a remove goroutine for each disk to accelerate removal.
Currently the code assumed some orthogonal requirements
which led situations where when we have a setup where
we have let's say for example 168 drives, the final
set_drive_count chosen was 14. Indeed 168 drives are
divisible by 12 but this wasn't allowed due to an
unexpected requirement to have 12 to be a perfect modulo
of 14 which is not possible. This assumption was incorrect.
This PR fixes this old assumption properly, also adds
few tests and some negative tests as well. Improvements
are seen in error messages as well.
- Remove the requirement to honor storage class for deletes
- Improve `posix.DeleteFileBulk` code to Stat the volumeDir
only once per call, rather than for all object paths.
Recent modification in the code led to incorrect calculation
of offline disks.
This commit saves the endpoint list in a xlObjects then we know
the name of each disk.
lock ownership is limited to endpoints on first zone,
as we do not hold locks on other zones in an expanded
setup. current code unintentionally expired active locks
when it couldn't see ownership from the secondary zone
which leads to unexpected bugs as locking fails to work
as expected.
