[zfs-discuss] how to measure in kernel how much time one operation takes

what call to be used in kernel to measure time taken for a operation if time quantum i s smaller than tick(frequency). i tried using ddi_get_lbolt at time t1 and t2.(at time t1 operation started and t2 it finished) but it always gives me zero(t2-t1). This message posted from opensolaris.org

Hi, Thanks for your input. Unfortunately, all 3 drives are identical Seagate 7200.11 drives which I bought separately and they are attached in no particular order. Thanks about the /dev/zero remark, I didn't know that. >From what I've seen this afternoon, I'm starting to suspect a >hardware/f

Re: [zfs-discuss] Cifs and Solaris

Yes, but not in-kernel. If you want CIFS on S10, use Samba. -- Fred On Apr 18, 2008, at 7:42 AM, Sengor wrote: > Hi all, > > A bit confused now... Wasn't Samba an implementation of CIFS which > also runs on Solaris? > > On Sat, Apr 19, 2008 at 12:26 AM, Tim <[EMAIL PROTECTED]> wrote: >> >> >> O

Re: [zfs-discuss] Cifs and Solaris

Correct. Of course the in-kernel CIFS stack will make it into the next "marketing release" (or whatever you want to call it, the thing that we think of as "Solaris 11.") It will be in the upcoming supported release of OpenSolaris. It will appear in other, supported distributions of OpenSolaris. B

Re: [zfs-discuss] Cifs and Solaris

Hi all, A bit confused now... Wasn't Samba an implementation of CIFS which also runs on Solaris? On Sat, Apr 19, 2008 at 12:26 AM, Tim <[EMAIL PROTECTED]> wrote: > > > On Fri, Apr 18, 2008 at 9:12 AM, Zlotnick Fred <[EMAIL PROTECTED]> > wrote: > > The in-kernel CIFS stack is not in Solaris 10 Upd

Re: [zfs-discuss] Cifs and Solaris

The in-kernel CIFS stack is not in Solaris 10 Update 5, and will never appear in any Solaris 10 update, because the kernel changes required are too invasive. You need OpenSolaris. -- Fred On Apr 18, 2008, at 2:56 AM, Mertol Ozyoney wrote: > Hi ; > > Cant remember on top of my head. Do solaris l

Hi ; Cant remember on top of my head. Do solaris latest version support Cifs ? Or do we need Open solaris ? Best regard Mertol http://www.sun.com/emrkt/sigs/6g_top.gif Mertol Ozyoney Storage Practice - Sales Manager Sun Microsystems, TR Istanbul TR Phone
