This is in preparation for updated admin heal API.
* Improve case analysis of healFormatXL() - fixes a case where disks
could have unhandled errors.
* Simplify healFormatXLFreshDisks() and healFormatXLCorruptedDisks()
to share more code and handle fewer cases for improved simplicity
and reduced code repetition.
* Fix test cases.
This patch also reverts previous changes which were
merged for migration to the newer disk format. We will
be bringing these changes in subsequent releases. But
we wish to add protection in this release such that
future release migrations are protected.
Revert "fs: Migration should handle bucketConfigs as regular objects. (#4482)"
This reverts commit 976870a391.
Revert "fs: Migrate object metadata to objects directory. (#4195)"
This reverts commit 76f4f20609.
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.
rpcClient should attempt a reconnect if the call fails
with 'rpc.ErrShutdown' this is needed since at times when
the servers are taken down and brought back up.
The hijacked connection from net.Dial is usually closed.
So upon first attempt rpcClient might falsely indicate that
disk to be down, to avoid this state make another dial attempt
to really fail.
Fixes#3206Fixes#3205
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.
- Fix distributed branch to be able to run FS version.
- Fix distributed branch to be able to run XL local disks.
- Ignore initialization failures of notification and bucket
policies, the codepath should load whatever is possible.
