I have two 500 GB drives on my system that are attached to built-in SATA ports on my Asus M4A785-M motherboard, running in AHCI mode. If I shut down the system, remove either drive, and then try to boot the system, it will fail to boot. If I disable the splash screen, I find that it will display the SunOS banner and the hostname, but it never gets as far as the "Reading ZFS config:" stage. GRUB is installed on both drives, and if both drives are present, I can flip the boot order in the BIOS and still have it boot successfully. I can even move one of the mirrors to a different SATA port and still have it boot. But if a mirror is missing, forget it. I can't find any log entries in /var/adm/messages about why it fails to boot, and the console is equally uninformative. If I check fmdump, it reports an empty fault log.
If I throw in a blank drive in place of one of the mirrors, the boot still fails. Needless to say, this pretty much makes the whole idea of mirroring rather useless. Any idea what's really going wrong here? -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
