http://research.cs.wisc.edu/adsl/Publications/corruption-fast08.html I don't think you are at risk of that. The above paper shows that usually drive corruption involves a small number of sectors. ~50 errors out of a 3TB disk isn't much. The "dup" and "copies=" option just allows you to have a copy of each important block that's not on one of those 50 sectors. > On reading more about ZFS, is it true the latest source code isn't > available for ZFS?

But the current version works pretty well, better than any other filesystem for large amounts of storage where reliability is desired. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
