> > I think it is incorrect to assume that a failure with ZFS that cannot be > recovered could be recovered if you used UFS with fsck. i think it is incorrect to not read carefully. So explanation - ZFS failure NOT caused by disks failure cannot be usually recovered. But even if i am wrong at this, rest still apply. > What fsck fixes in > other file systems doesn't apply to ZFS by ZFS's design. fsck deals with > fixing superblock inconsistancies on non-journaled file systems (like > UFS/UFS2), not resurecting corrupted blocks on a disk. > > http://www.c0t0d0s0.org/archives/6071-No,-ZFS-really-doesnt-need-a-fsck.html yes i know that article. And it is truly funny for me to know people do think this way.
