Fixed In Version: ceph-19.2.1-37.el9cp Doc Type: Bug Fix
Doc Text:
.Space larger than the NFS export disk size can no longer be allocated Previously, an empty file could be created without storage blocks allocated. These empty files could cause write operations to fail when writing to the desired file region, with a command such as `fallocate`. With this fix, the `fallocate` command fails on the NFS mount point with an "Operation not supported" error and no empty files are created without storage blocks allocated.
