Re: [zfs-discuss] ZFS, Oracle and Nexenta

2011-05-25 Thread a . smith
Still i wonder what Gartner means with Oracle monetizing on ZFS.. It simply means that Oracle want to make money from ZFS (as is normal for technology companies with their own technology). The reason this might cause uncertainty for ZFS is that maintaining or helping make the open source v

Hi, I am using FreeBSD 8.2 in production with ZFS. Although I have had one issue with it in the past but I would recommend it and I consider it production ready. That said if you can wait for FreeBSD 8.3 or 9.0 to come out (a few months away) you will get a better system as these will i

Re: [zfs-discuss] Drive i/o anomaly

It is a 4k sector drive, but I thought zfs recognised those drives and didn't need any special configuration...? 4k drives are a big problem for ZFS, much has been posted/written about it. Basically, if the 4k drives report 512 byte blocks, as they almost all do, then ZFS does not detect and

Basically I think yes you need to add all the vdevs you require in the circumstances you describe. You just have to consider what ZFS is able to do with the disks that you give it. If you have 4x mirrors to start with then all writes will be spread across all disks and you will get nice per

Ok, think I have the biggest issue. The drives are 4k sector drives, and I wasn't aware of that. My fault, I should have checked this. Had the disks for ages and are sub 1TB so had the idea that they wouldn't be 4k drives... I will obviously have to address this, either by creating a pool u

Quoting Bob Friesenhahn : What function is the system performing when it is so busy? The work load of the server is SMTP mail server, with associated spam and virus scanning, and serving maildir email via POP3 and IMAP. Wrong conclusion. I am not sure what the percentages are percent
