I''ve got 12Gb or so of db+web in a zone on a ZFS filesystem on a mirrored zpool. Noticed during some performance testing today that its i/o bound but using hardly any CPU, so I thought turning on compression would be a quick win. I know I''ll have to copy files for existing data to be compressed, so I was going to make a new filesystem, enable compression and rysnc everything in,

I am trying to give a general user permissions to create zfs filesystems in the rpool. zpool set=delegation=on rpool zfs allow <user> create rpool both run without any issues. zfs allow rpool reports the user does have create permissions. zfs create rpool/test cannot create rpool/test : permission denied. Can you not allow to the rpool? -- This message posted from opensolaris.org

We are going to be migrating to a new EMC frame using Open Replicator. ZFS is sitting on volumes that are running MPXIO. So the controller number/disk number is going to change when we reboot the server. I would like to konw if anyone has done this and will the zfs filesystems "just work" and find the new disk id numbers when we go to zfs import the pool. Our process would be: zfs
