Then metadtaa are kept in 2 or three copies, depending on type. Your data resilience depends on pool configuration obviously - so zfs will always be able to detect data corruption and possibly fix it if your pool has redundant config. However if your memory is corrupting data then if data were corrupted before application issued write then from zfs point of view everything will be fine. If it was corrupted later then zfs should detect it and correct in redundant config. -- Best regards, Robert Milkowski mailto:[EMAIL PROTECTED] http://milek.blogspot.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
