Re: [OpenIndiana-discuss] cleaning out stale entries in zpool cache

Dan, Actually you'll need to 'dd' the end of the disk since it's labels 2 and 3 that are still visible to the system. I would start by dd-ing the last mega or so of the p0 device. Good luck, George On Oct 24, 2011, at 11:42 AM, Dan Swartzendruber wrote: > George Wilso

Dan, I suspect that the problem is that your original pool was built using a couple of p0 devices. Can you do a 'zdb -l /dev/rdsk/c0t50014EE204411A53d0p0' and send that output? Thanks, George On Oct 24, 2011, at 9:51 AM, Dan Swartzendruber wrote: > > To be (maybe) clearer: these disks were i

Re: [OpenIndiana-discuss] cleaning out stale entries in zpool cache

Dan, What is happening is that 'zpool import' is picking up the old zfs labels on each of those disks. One easy way to fix this is to run fdisk on each of the disks below and blow away the fdisk partition. You'll want to ensure that they are not really being used by anything else. Another opt

Bryan, I believe you're hitting a kernel fragmentation issue which causes the system to hang waiting for memory. I have a fix which may help you. I'm be submitting this for review in the next day or two. Thanks, George On Oct 21, 2011, at 9:06 AM, Bryan S. Leaman wrote: > On 10/21/2011 4:16
