https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D236504 Mark Johnston <markj@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |markj@FreeBSD.org --- Comment #9 from Mark Johnston <markj@FreeBSD.org> --- I don't quite understand why the test is generating these errors in the fir= st place. If the checksum is failing, it means that we saw the UFS2 magic num= ber in the superblock, so we're probably not looking at random garbage. Is it possible the taste is racing with synchronization of a new gmirror disk, and seeing a partial write of a copied superblock? --=20 You are receiving this mail because: You are the assignee for the bug.=
