That would surprise me. Can it be that you are saturating the PCI slot you 2342 card sits in ? IIRC not every slot on V240 can handle dual port 2342 card going at full rate. I didn't understand what you mean? there is only 3 slots on v240, which of them cannot handle dual HBA? Generalizations

The Xraid is a very well thought of storage device with a heck of a price point. Attached is an image of the Settings/Performance Screen where you see Allow Host Cache Flushing. I think when you use ZFS, it would be best to uncheck that box. This is what happen when you do use GUI in your

I was able to duplicate this problem on a test Ultra 10. I put in a workaround by adding a service that depends on /milestone/multi-user-server which does a 'zfs share -a'. It's strange this hasn't happened on other systems, but maybe it's related to slower systems... Ben This message

You might set zil_disable to 1 (_then_ mount the fs to be shared). But you're still exposed to OS crashes; those would still corrupt your nfs clients. -r cedric briner writes: Hello, I wonder if the subject of this email is not self-explanetory ? okay let'say that it is not. :)

So first of all, we're not proposing dumping to a filesystem. We're proposing dumping to a zvol, which is a raw volume implemented within a pool (see the -V option to the zfs create command). As Malachi points out, the advantage of this is that it simplifies the ongoing administration. You
