You cannot unmount a pool. You can only unmount a filesystem. That the default name of the pool's filesystem is the same as the name of the pool is an artifact of the implementation. Surely, you can unmount the filesystem. That is not illegal. But you've removed a live pool WITHOUT exporting it. I can understand that you make that mistake because you take what you know from other filesystems and you apply that to ZFS. >So how on earth should a simple user know that, if he knows that filesystems >properly unmounted using the umount cmd?? Reading the documentation. The zpool and zfs commands are easy to use and perhaps this stops you and others from reading, e.g., http://docs.sun.com/app/docs/doc/819-5461/gavwn?l=en&a=view And before you use ZFS you must understand some of the basic concepts; rather than having a device which you can mount with "mount", you have a "pool" and that "pool" is owned by the system. > >And again: Why should a 2 weeks old Seagate HDD suddenly be damaged, if there >was no shock, hit or any other event like tht? If you removed the device from a live pool and moved it on another system and them moved it back, then, yes, you could have problems. You I'd suppose that the system shouldn't go online and requiring an import (-f). > >It is of course easier to blame the stupid user instead of having proper >documentation and emergency tools to handle that. The document explains that must use export in order to remove pools from one system to another. I'm not sure how the system can prevent that; there's no "lock" on your USB slots. As for the other problems with nv107, each time we change a lot of software; and sometimes we change important parts of the sofware; e.g., in nv107 we changed to a newer version of Xorg. The cutting edge builds vary in quality.
