This PR introduces ReloadFormat API call at objectlayer
to facilitate this. Previously we repurposed HealFormat
but we never ended up updating our reference format on
peers.
Fixes#5700
This change let the server return the S3 error for a key rotation
if the source key is not valid but equal to the destination key.
This change also fixes the SSE-C error messages since AWS returns error messages
ending with a '.'.
Fixes#5625
This change sets the storage class of the object-info if a storage
class was specified during PUT. The server now replies with the
storage class which was set during uploading the object in FS mode.
Fixes#5777
Default installations of cloned VMs on VMware like env
might experience serious problems with time skewing,
allow for a higher value instead of 3 seconds we are
moving to 15 minutes just like API level skew.
Access to internet and configuring ntp might not be possible,
in such situations providing atleast a 15 minute skew could
cater for majority of situations.
Since we do not re-use storageDisks after moving
the connections to object layer we should close them
appropriately otherwise we have a lot of connection
leaks and these can compound as the time goes by.
This PR also refactors the initialization code to
re-use storageDisks for given set of endpoints until
we have confirmed a valid reference format.
An issue was reproduced when there a no more inodes
available on an existing setup of 4 disks, now we
took one of the disks and reformatted it to relinquish
inodes. Now we attempt to bring the fresh disk back
into setup and perform a heal - at this point creating
new `format.json` fails on existing disks since they
do not have more inodes available.
At this point due to quorum failure, we end up deleting
existing `format.json` as well, this PR removes the code
which deletes existing `format.json` as there is no need
to delete them.
Previous PR 2afd196c83 fixed
the issue of quorum based listing for regular objects, this
PR continues on this idea by extending this support to
object directory prefixes as well.
Fixes#5733
Set GOPATH string to empty in build-constants.go
Check for both compile time GOPATH and default GOPATH
while trimming the file path in the stack trace.
Fixes#5741
This PR fixes two different variant of deadlocks in
notification.
- holding write lock on the bucket competing with read lock
- holding competing locks on read/save notification config
This PR adds disk based edge caching support for minio server.
Cache settings can be configured in config.json to take list of disk drives,
cache expiry in days and file patterns to exclude from cache or via environment
variables MINIO_CACHE_DRIVES, MINIO_CACHE_EXCLUDE and MINIO_CACHE_EXPIRY
Design assumes that Atime support is enabled and the list of cache drives is
fixed.
- Objects are cached on both GET and PUT/POST operations.
- Expiry is used as hint to evict older entries from cache, or if 80% of cache
capacity is filled.
- When object storage backend is down, GET, LIST and HEAD operations fetch
object seamlessly from cache.
Current Limitations
- Bucket policies are not cached, so anonymous operations are not supported in
offline mode.
- Objects are distributed using deterministic hashing among list of cache
drives specified.If one or more drives go offline, or cache drive
configuration is altered - performance could degrade to linear lookup.
Fixes#4026
This is a trival fix to support server level WORM. The feature comes
with an environment variable `MINIO_WORM`.
Usage:
```
$ export MINIO_WORM=on
$ minio server endpoint
```
Object deletion should not be possible if quorum is not
available. This PR updates deleteObject() to check for
quorum errors before proceeding with object deletion.
Fixes#5535
