Thanks Jim and Richard - zpool import -f mypool worked. This is a mystery to me since I had done a zpool import before and it did not see mypool, but does now. Anyway I'm in good shape now. Steve C. Jim Dunham wrote: > Steve, > >> Can someone tell me or point me to links that describe how

[zfs-discuss] Moving zfs pool to new machine?

Can someone tell me or point me to links that describe how to do the following. I had a machine that crashed and I want to move to a newer machine anyway. The boot disk on the old machine is fried. The two disks I was using for a zfs pool on that machine need to be moved to a newer machine no

[zfs-discuss] Replacing a drive, resilvering results in checksum errors?

This is probably a FAQ but I have been unable to turn up the answer in searches, thanks for your patience. I have a zfs testbed set up with 3x 200 GB SATA drives in raidz. I pulled a drive (ad4) and replaced it to experience the rebuild procedure. After scrubbing/resilvering, I get the status

Re: [zfs-discuss] Hierarchal zfs mounts

No boot problems. The zfs filesystems are in the same pool. What would be nice is something like zfs set mountorder=1 local/apps zfs set mountorder=2 local/apps-bin or something along that line. So one zfs filesystem can be reliably mounted to a point inside another zfs filesystem. This
