Hi all, According to the documentation the allocsize mount option: "Sets the buffered I/O end-of-file preallocation size when doing delayed allocation writeout" Will this value limit "extent" sizes to be be no smaller than the allocsize? I have set the following mount options: (rw,noatime,nodiratime,logbufs=8,allocsize=512m) And yet, depending on the workload, the extent sizes are often 1 or 2 orders of magnitude lower than 512 MB ... If I wanted to do further reading on the subject, can someone point me to an approximate location in the code where the size of a newly created extent is determined?
