Jay Zhuang a89740fbc6 Fix unittest no space issue (#8204) ... Summary: Unittest reports no space from time to time, which can be reproduced on a small memory machine with SHM. It's caused by large WAL files generated during the test, which is preallocated, but didn't truncate during close(). Adding the missing APIs to set preallocation. It added arm test as nightly build, as the test runs more than 1 hour.
