I haven't. Haven't really seen anyone say they have either, in a way that w= as=20 due to a ZFS bug. I'm using it for several machines (both private and in production). Two of= =20 them are doing raidz2 with 5 and 6 disks respectively, another two are doin= g=20 three-way mirroring. Based on past experience and behavior in various edge cases (port outtages,= =20 crashes causing rebuilds, etc), I feel safer with ZFS than without, even if= =20 the implementation is not as mature as UFS. However, the fact that I "feel= =20 safe" is of course not very objective nor useful ;) Just with these select few machines, I have already had snapshots save me a= t=20 least once and checksumming "sort of" saved me once. And knowing that 'zpoo= l=20 scrub' really tests your integrity properly is *so* re-assuring I can't eve= n=20 begin to describe it. That said, no raid/storage solution is ever going to be perfect. Insert=20 standard rant about keeping backups here. =2D-=20 / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller ' Key retrieval: Send an E-Mail to getpgpkey@scode.org E-Mail: peter.schuller@infidyne.com Web: http://www.scode.org --nextPart1743473.odSBQiRclx Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4 (FreeBSD) iD8DBQBHcGCADNor2+l1i30RAlKAAKDKFR2qp0t5ttfpsn673ZwVTvOCBACg7Xi6 SUMJZEpTIUJZufAdzfREPB4= =mpNn -----END PGP SIGNATURE----- --nextPart1743473.odSBQiRclx--
