From 73187559a6b8a04f1db3dd5979a82421cdd47c76 Mon Sep 17 00:00:00 2001 From: Kirk McKusick Date: Wed, 30 Jul 2014 14:52:04 +0000 Subject: [PATCH] When restoring a UFS dump onto a ZFS filesystem, an assertion in restore was failing because ZFS was reporting a blocksize that was not a multiple of 1024. Replace restore's failed assertion with code that writes restored files in a blocksize that works for restore (a multiple of 1024) despite being non-optimal for ZFS.
