One of the things that I have taken for granted was that I can *always* boot a Sun server with a CDROM or DVD or jumpstart "boot net -srv" and get to a prompt. That allows me to fsck filesystems and ufsdump to tape if needed. In fact, I have generally done obscure things like fully install a server and then, with everything working fine, booted with CDROM and dumped the system to tape and I call that my "ground zero" backup tape. Everything that follows after that is incremental for a while until the next level 0 dump. [1]
Well I just did a boot net -sv on my server here and have snv-b52 at the prompt. I was able to fsck the basic UFS filesystems on this machine as it was running snv-b46. I attached a tape drive before booting and am therefore able to ufsdump and verify the contents of the snv-b46 UFS filesystems to tape. This is all a good thing. My problem is that the snv-46 machine also had a zpool and multiple ZFS filesystems. Simply running "zfs list" here at the prompt gets me nothing of course. Can I create or otherwise recover some XML file from the snv-46 server filesystems in order to gain access to those ZFS filesystems from this "noot boot" shell? Is there any way to backup those ZFS filesystems while booted from CDROM/DVD or boot net ? Essentially, if I had nothing but bare metal here and a tape drive can I access the zpool that resides on six 36GB disks on controller 2 or am I dead in the water ? -- Dennis Clarke _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
