Well, the zfs send/receive finally finished, at a size of 9.56TB (apologies for the HTML, it was the only way I could make the columns readable): root@archive:/home/admin# zfs get all archive1/RichRAID NAME PROPERTY VALUE SOURCE archive1/RichRAID type volume - archive1/RichRAID creation Fri Sep 14 4:17 2012 - archive1/RichRAID used 9.56T - archive1/RichRAID available 1.10T - archive1/RichRAID referenced 9.56T - archive1/RichRAID compressratio 1.00x - archive1/RichRAID reservation none default archive1/RichRAID volsize 5.08T local archive1/RichRAID volblocksize 8K - archive1/RichRAID checksum on default archive1/RichRAID compression off default archive1/RichRAID readonly off default archive1/RichRAID copies 1 default archive1/RichRAID refreservation none default archive1/RichRAID primarycache all default archive1/RichRAID secondarycache all default archive1/RichRAID usedbysnapshots 0 - archive1/RichRAID usedbydataset 9.56T - archive1/RichRAID usedbychildren 0 - archive1/RichRAID usedbyrefreservation 0 - archive1/RichRAID logbias latency default archive1/RichRAID dedup off default archive1/RichRAID mlslabel none default archive1/RichRAID sync standard default archive1/RichRAID refcompressratio 1.00x - archive1/RichRAID written 9.56T - So used is 9.56TB, volsize is 5.08TB (which is the amount of data used on the volume). The Mac connected to the FC target sees a 5.6TB volume with 5.1TB used, so that makes sense-- but where did the other 4TB go? (I'm about at the point where I'm just going to create and export another volume on a second zpool and then let the Mac copy from one zvol to the other-- this is starting to feel like voodoo here.) -- Dave Pooser Manager of Information Services Alford Media http://www.alfordmedia.com
