Hi Luke, That's terrific!
You know you might be able to tell ZFS which disks to look at. I'm not sure. It would be interesting, if anyone with a Thumper could comment on whether or not they see the import time issue. What are your load times now with MPXIO? Best Regards, Jason On 12/7/06, Luke Schwab <[EMAIL PROTECTED]> wrote:
Jason, Sorry, I don't have IM. I did make some progress on testing. The solaris 10 OS allows you to kind of lun mask within the fp.conf file by creating a list of luns you don't want to see. This has improved my time greatly. I can now create/export within a second and import only takes about 10 seconds. What a differnce compared to the 5-8 minutes I've been seeing! but this not good if my machine needs to see LOTs of luns. It would be nice if there was a feature in zfs where you could specify which disk the the pool resides instead of zfs looking through every disk attached to the machine. Luke Schwab --- "Jason J. W.
