From 05ff35c602827a0f03659ec974c67b3fb5bf1c0b Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Wed, 23 Feb 2011 13:57:50 -0800 Subject: [PATCH] Increase fragment size to block size The underlying storage pool actually uses multiple block size. Under Solaris frsize (fragment size) is reported as the smallest block size we support, and bsize (block size) as the filesystem's maximum block size. Unfortunately, under Linux the fragment size and block size are often used interchangeably. Thus we are forced to report both of them as the filesystem's maximum block size.
