I have IBM server with HW RAID10 made from 36 disks. I'm using =46reeBSD 9.2-RELEASE. =46rom system point of view my raid is seen as 65TiB drive at /dev/mfid0 =46rom Z=46S point of view it's plain stripe as one zvol (on mfid0p2).

This machine has been working happily, until today when I did =22reboot=22= . After that system is unbootable, and throws on boot: Z=46S: i/o error - all block copies unavailable Z=46S: can't find root dsl=5Fdir My pool is ok, I can boot to it through external ISO (f.e. mfsbsd). Also =22status=22 shows that everything's fine (screenshot of what my kvm= shows there): http://s.verknowsys.com/5f6de0dfbc6d576dc53c000409a27e344e60adee.png I saw in previous thread (http://marc.info/=3Fl=3Dfreebsd-fs&m=3D12580756= 4213035&w=3D2), that there's a patch for raidz that somewhat fixes that i= ssue in =46reeBSD 8.x with raidz. So far I did try many =22solutions=22 but none helped in that matter. I did try: update bootcode, move /boot from one place to other, update ke= rnel, switch between kernel / kernel.old, and several more or less stupid= attempts to fix it Any ideas=3F -- Daniel (dmilith) Dettlaff
