Re: [zfs-discuss] SSD vs hybrid drive - any advice?

I am using the OCZ Vertex 3, 240GB. When I boot Solaris 11 Express, on the splash screen, there is a small red line traveling from left to right. With this SSD, the red line is traveling two times over the screen before S11E has booted up. With hard disk, the red line traveled several times

I dont get it. I created users with System - Administration - Users and Groups meny. I thought every user will get his own ZFS filesystem? But when I do # zfs list I can not see a zfs listing for each user. I only see this: rpool/export 60,4G 131G32K /export

That is correct. Those of us working in ZFS land recommend one file system per user, but the software has not yet caught up to that model. The wheels are turning though. When I get back to office, I will send out some steps that might help during this transition. Thanks, Cindy -- This

Ah, ok. That explains it all. Thanx. And yes, df did the trick. So, if I want each user to have his own zfs filesystem, I just create the filesystem, and then copy everything from /export/home, and then I fire up the GUI and point to the new zfs filesystem? That is all? I dont have to edit
