A zfs list shows less space (incorrect) on the single drive compared to the raidz. Doing a tar on both directories gives 2 1.2G files so the data is actually present on both packs (plus I used CPIO to copy the data from the single to the raidz) Is it possible for data corruption on the single drive to not show the extra space as being used?Received on Mon May 18 2009 - 10:55:28 UTC
