[zfs-discuss] ZFS Locking Up periodically

2009-04-01 Thread Andrew Robert Nicols
I've recently re-installed an X4500 running Nevada b109 and have been experiencing ZFS lock ups regularly (perhaps once every 2-3 days). The machine is a backup server and receives hourly ZFS snapshots from another thumper - as such, the amount of zfs activity tends to be reasonably high. After

I'm going to try to move one of my disks off my rpool tomorrow (since it's a mirror) to a different controller. According to what I've heard before, ZFS should automagically recognize this new location and have no problem, right? Or do I need to do some sort of detach/etc. process first?

Re: [zfs-discuss] is zpool export/import | faster than rsync or cp

Hi Harry, I was on vacation so am late to this discussion. For this part of your question: The zpool export/import feature is a pool-level operation for moving the pool, disks, and data to another system. For moving data from one pool to another pool, you would want to use zfs send/recv,
