This is a ZFS issue because ZFS is advertised as being the most resilient file system currently available; however, a community leader in the FreeNAS forums (though, as pointed out by Daniel Becker, one without knowledge of ZFS internals) has argued repeatedly and strongly, and in detail that this robustness is severely compromised by using ZFS without ECC memory. Further he argues that ZFS without ECC memory is more vulnerable than other file systems to data corruption and that this corruption is likely to silently cause complete and unrecoverable pool failure. This in turn, if true, is an issue because ZFS is increasing being used on systems that either are not using or can not use ECC memory. Jason Belec has asserted that his testing shows that there is not an increased chance of partial or complete loss of data when not using ECC memory. Daniel Becker has cogently argued that the scenario and logic in the warning is incorrect and that it has not been shown that ZFS is in fact more vulnerable than other file systems when ECC memory is not used. While I am reassured by their responses, I would still like an authoritative and preferably definitive answer as to whether or not ZFS is in fact any more or less vulnerable than other file systems when ECC memory is not used. So I'm going to ask my question on the Open ZFS developer's list. (Since that's the only list they have.)
