Hi, Can anyone explain the following to me? Two zpool devices points at the same data, I was installing osol 2008.11 in xVM when I saw that there already was a partition on the installation disk. An old dataset that I deleted since i gave it a slightly different name than I intended is not removed under /dev. I should not have used that name, but two device links should perhaps not point to the same device ether.... zfs list |grep xvm/dsk zpool01/xvm/dsk 25.0G 2.63T 24.0K /zpool01/xvm/dsk zpool01/xvm/dsk/osol01-dsk01 10G 2.64T 2.53G - zpool01/xvm/dsk/ubuntu01-dsk01 10G 2.64T 21.3K - # ls -l /dev/zvol/dsk/zpool01/xvm/dsk total 3 lrwxrwxrwx 1 root root 41 Feb 10 18:19 osol01-dsk01 - > ../../../../../../devices/pseudo/zfs at 0:4c lrwxrwxrwx 1 root root 41 Feb 10 18:14 ubuntu-01-dsk01 - > ../../../../../../devices/pseudo/zfs at 0:4c lrwxrwxrwx 1 root root 41 Feb 10 18:19 ubuntu01-dsk01 - > ../../../../../../devices/pseudo/zfs at 0:5c # zpool history |grep xvm 2009-02-08.22:42:12 zfs create zpool01/xvm 2009-02-08.22:42:23 zfs create zpool01/xvm/media 2009-02-08.22:42:45 zfs create zpool01/xvm/dsk 2009-02-10.18:14:41 zfs create -V 10G zpool01/xvm/dsk/ubuntu-01-dsk01 2009-02-10.18:15:10 zfs destroy zpool01/xvm/dsk/ubuntu-01-dsk01 2009-02-10.18:15:21 zfs create -V 10G zpool01/xvm/dsk/ubuntu01-dsk01 2009-02-10.18:15:33 zfs create -V 10G zpool01/xvm/dsk/osol01-dsk01 # uname -a SunOS ollespappa 5.11 snv_107 i86pc i386 i86xpv While I am writing, is there any known issues with sharemgr and zfs in this release? svc:/network/shares/group:zfs hangs when going down since sharemgr stop zfs never returns...

I tried to export the zpool also, and I got this, the strange part is that it sometimes still thinks that the ubuntu-01-dsk01 dataset exists: # zpool export zpool01 cannot open ''zpool01/xvm/dsk/ubuntu-01-dsk01'': dataset does not exist cannot unmount ''/zpool01/dump'': Device busy But: # zfs destroy zpool01/xvm/dsk/ubuntu-01-dsk01 cannot open ''zpool01/xvm/dsk/ubuntu-01-dsk01'': dataset does not exist Regards On Feb 12, 2009, at 11:51 PM, Henrik Johansson wrote:> Hi, > > Can anyone explain the following to me? > > Two zpool devices points at the same data, I was installing osol > 2008.11 in xVM when I saw that there already was a partition on the > installation disk.

I created a zpool, created a dataset, then destroyed the zpool. When creating a new zpool on the same partitions/disks as the destroyed zpool, upon export I receive the same message as you describe above, even though I never created the dataset in the new pool. Creating a dataset of the same name and then destroying it doesn''t seem to get rid of it, either. I never did remember to file a bug for it...
