Well, I'm not sure how much load do you mean so I'll tell you what I did ;). I've set a striped zvol and push 4 parallel dd reading from /dev/zero and 8 tars decompresing src's and ports tarballs. Just to add some 'noise' to the box, a buildworld was also running although from other disk behind other controller ... after some time, the noise coming from the disks changed, I thought, something has happened ... well, tar finished successfully and only the 4 dd continue writing on the zvol. About 6?GB on disk and several thousand files ... So I stop the dd's and run a scrub on the zvol that was completed with 0 errors. After that, I destroyed the striped zvol and set a mirrored one. From them, samba shares, some netcat, scp's ... 24GB has been writen with a more 'normal' load and still without any apparent problem. I don't like too much this _scientific_ approach, but I feel pretty confident about the controller ;). > For the commit: > > 1) I don't have a commit bit, but we may get that in (by the help of > somebody else) > 2) we're already in a freeze situation - don't expect that to be in > -STABLE before 7.1-RELEASE (also it needs to be in HEAD first and then > may get MFC'd).
