> Improve DiskCheckUtil.checkReadWrite to tolerate disk full
> ----------------------------------------------------------

> Key: HDDS-14888
> URL: https://issues.apache.org/jira/browse/HDDS-14888
> Project: Apache Ozone
> Issue Type: Improvement
> Reporter: Sammi Chen
> Assignee: Sammi Chen
> Priority: Major
> Labels: pull-request-available
>
> DiskCheckUtil.checkReadWrite does file write and read check to make sure disk
> is writable and readable.
> If disk is full, it will catch the exception and return false.
> The outer StorageVolume#check will decide whether mark this time volume check
> as fail or not, depending on whether volume has more than 100B *2 free space.
> As the disk space will dynamically change, so there is change that
> checkReadWrite() is failed due to disk full, while when below logic is
> evaluated, it has enough available space again.
> {code:java}
> if (!diskChecksPassed && getCurrentUsage().getAvailable() <
> minimumDiskSpace) {
> {code}
> The goal of this target is to analysis the exception in checkReadWrite()
> directly, so that disk full case will not return false.
