I believe this is what you're hitting: 6456888 zpool attach leads to memory exhaustion and system hang We are currently looking at fixing this so stay tuned. Thanks, George Daniel Rock wrote: Joseph Mocker schrieb: Today I attempted to upgrade to S10_U2 and migrate some mirrored UFS SVM

Hi Bob, you are using some non-Sun SCSI HBA. Could you please be more specific about HBA model and driver? You are getting pretty the same high CPU load with write to single-disk UFS and raid-z. This may mean that the problem is not with ZFS itself. Victor Bob Evans wrote: Robert, Sorry

First, I apologize, I listed the Antares in my original post, it was one of two scsi cards I tested with. The posted CPU snapshots were from the LSI 22320 card (mentioned below). I've tried this with two different SCSI cards. As far as I know, both are standard SCSI cards used for Suns.
