Then I searched and found a thread were Eric also talked: http://lkml.org/lkml/2008/5/16/390 http://hightechsorcery.com/2008/06/linux-write-barriers-write-caching- lvm-and-filesystems If I understand correctly, turning off disk cache write cache should be enough to be save, even when using LVM. Is it really XEN that messed the disk, or something else? Could the Areca controller driver do something wrong? I'd really love to get a stable and data-secure system, as you might understand. mfg zmi -- // Michael Monnerie, Ing.BSc ----- http://it-management.at // Tel: 0660 / 415 65 31 .network.your.ideas. // PGP Key: "curl -s http://zmi.at/zmi.asc | gpg --import" // Fingerprint: AC19 F9D5 36ED CD8A EF38 500E CE14 91F7 1C12 09B4 // Keyserver: wwwkeys.eu.pgp.net Key-ID: 1C1209B4 _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
