Hmm, it is a non fatal error for gjournal, I'm kind of surprised it's a=20 fatal one for ZFS.. If the cache flush really failed (eg due to a stuffed disk) then there=20 really is a problem, but IMO it is likely this is going to be caught by=20 a read or a write operation very soon. If it is a transient error then panicing seems to be about the worse=20 response :) =2D-=20 Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C --nextPart9420780.QCkM6EtnH1 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (FreeBSD) iD8DBQBGLdgY5ZPcIHs/zowRArh2AKCQlKeArXs0ABVkMaT2n6/LBRBo8ACdENaP I1Murus0ODt0T5PIrHq+ivU= =3e2K -----END PGP SIGNATURE----- --nextPart9420780.QCkM6EtnH1--
