Hi I got a san disk visible on two nodes (global or zone). On the first node, i can create a pool using zpool create x1 sandisk. If i try to reuse this disk on the first node, i got a vdev in use warning. If i try to create a pool on the second node using the same disk, zpool create x2 sandisk,

Hi! I just want to check with the community to see if this is normal. I have used a X4500 with 500Gb disks and I'm not impressed by the copy performance. I can run several jobs in parallel and get close to 400mb/s but I need better performance from a single copy. I have tried to be EVIL as

[zfs-discuss] ZFS volume export to USB-2 or Firewire?

2008-04-08 Thread Bob Friesenhahn
Currently it is easy to share a ZFS volume as an iSCSI target. Has there been any thought toward adding the ability to share a ZFS volume via USB-2 or Firewire to a directly attached client? There is a substantial market for storage products which act like a USB-2 or Firewire drive. Some of

On my drive array (capable of 260MB/second single-process writes and 450MB/second single-process reads) 'zfs iostat' reports a read rate of about 59MB/second and a write rate of about 59MB/second when executing 'cp -r' on a directory containing thousands of 8MB files. This seems very similar

I didn't think that we had live upgrade support for zfs root filesystem yet. Original quote from Lori Alt: ZFS is ideally suited to making “clone and modify” fast, easy, and space-efficient. Both “clone and modify” tools will work much better if your root file system is ZFS. (The new install

Hi, This was taken from where? From liveupgrade??? As long as I know, liveupgrade works only with ufs. At the time of my first install I choose ufs exactly for the reason to be able to do liveupgrade. What you have there is something that I agree but NOT for liveupgrade but yes to work with

It's true that liveupgrade doesn't support zfs yet. That support will become available in the build 89 or 90 time frame, at the same time that zfs as a root file system is supported. Lori Ether.pt wrote: Hi, This was taken from where? From liveupgrade??? As long as I know, liveupgrade

[zfs-discuss] How many ZFS pools is it sensible to use on a single server?

In our environment, the politically and administratively simplest approach to managing our storage is to give each separate group at least one ZFS pool of their own (into which they will put their various filesystems). This could lead to a proliferation of ZFS pools on our fileservers (my current
