[zfs-discuss] Changing a VDEV GUID?
Hi ZFS fellows, I already seen on the archive of the list some of you doing some GUID change of a pool's VDEV, to allow a cloned disk to be imported on the same system as the source. Can someone explain in detail how to achieve that? Has already someone invented the wheel so I would not have to rewrite a tool to do it? Subsidiary: Is there an official response of Oracle in front of such case? How do they officially deal with Binary Copied disks, as it's common to do such copy with UFS to copy SAP environment or Databases... Thanks in advance, Thomas ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

You're probably hitting bug 7056738 - http://wesunsolve.net/bugid/id/7056738 Looks like it's not fixed yet @ oracle anyway... Were you using crypto on your datasets ?

I have tried OpenIndiana 151 and Solaris 11 Express (latest from Oracle) several times each as well as 2 new installs of Update 8. When I understand you right is your primary interest to recover your data on tank pool. Have you check the way to boot from a Live-DVD, mount your safe place and copy the data on a other machine? Hi Alexander, Yes of course...the problem is no version of Solaris can import the pool. Please refer to the first message in the thread.

Re: [zfs-discuss] Kernel panic on zpool import. 200G of data inaccessible!
Have you already extracted the core file of the kernel crash ? (and btw activated dump device for such dumping happen at next reboot...) Have you also tried applying the latest kernel/zfs patches and try importing the pool afterwards ? Thomas On 08/18/2011 06:40 PM, Stu Whitefish wrote: Hi Thomas, Thanks for that link. That's very similar but not identical. There's a different line number in zfs_ioctl.c, mine and Preston's fail on line 1815. It could be because of a difference in levels in that module of course, but the traceback is not identical either. Ours show brand_sysenter and the one you linked to shows brand_sys_syscall. I don't know what all that means but it is different. Anyway at least two of us have identical failures. I was not using crypto, just a plain jane mirror on 2 drives. Possibly I had compression on a few file systems but everything else was allowed to default. Here are our screenshots in case anybody doesn't want to go through the thread. http://imageshack.us/photo/my-images/13/zfsimportfail.jpg/ http://prestonconnors.com/zvol_get_stats.jpg I hope somebody can help with this. It's not a good feeling having so much data gone. Thanks for your help. Oracle, are you listening?
