[zfs-discuss] filebench for Solaris 10?

2008-02-16 Thread Bob Friesenhahn
Some of us are still using Solaris 10 since it is the version of Solaris released and supported by Sun. The 'filebench' software from SourceForge does not seem to install or work on Solaris 10. The 'pkgadd' command refuses to recognize the package, even when it is set to Solaris 2.4 mode. I

Yes, it does replicate data between controllers. Usualy it slows that a lot espacialy on wirte heavy environments. If you properly tune ZFS you may not need this feature for consistency... Mertol Ozyoney Storage Practice - Sales Manager Sun Microsystems, TR Istanbul TR Phone +902123352200 Mobi

I was indeed using the new CIFS, I tried making Samba go last night but it wasn't working out for whatever reason, and CIFS wouldn't work with my Windows Vista x64. I just BFUed to the 81 release which fixed my Vista connection problems, going to see if it fixes read/write too. Sam This me

Bob, Here is how you can tell the array to ignore cache sync commands and the force unit access bits...(Sorry if it wraps..) On a Solaris CAM install, the 'service' command is in "/opt/SUNWsefms/bin" To read the current settings: service -d arrayname -c read -q nvsram region=0xf2 host=0x00 sav

Hi Tim; 2540 controler can achieve maximum 250 MB/sec on writes on the first 12 drives. So you are pretty close to maximum throughput already. Raid 5 can be a little bit slower. Please try to distribute Lun's between controllers and try to benchmark by disabling cache mirroring. (it's di

Are you using the new CIFS server, or Samba? If you're using CIFS, it might be worth giving Samba a try. Enabling samba, plus the swat web management, is now just a case of: svcadm enable samba svcadm enable swat http://blogs.sun.com/timthomas/entry/samba_and_swat_in_solaris This message

It may not be relevant, but I've seen ZFS add weird delays to things too. I deleted a file to free up space, but when I checked no more space was reported. A second or two later the space appeared. And I'm also seeing zpool status report that drives are ok when one is disconnected. I have to
