So, in this thread, I haven't yet got the answer that I expect or believe. Because, the behavior I observed was: I did a "zfs send" from one system to another, received onto /localpool/backups. Side note, the receiving system has three pools: rpool, localpool, and iscsipool. Unfortunately, I sent the zfs properties with it, including the mountpoint. Naturally, there was already something mounted on / and /exports and /exports/home, so the zfs receive failed to mount on the receiving system, but I didn't notice that. Later, I rebooted. During reboot, of course, rpool mounted correctly on /, but then the system found the localpool/backups filesystems, and mounted /exports, /exports/home and so forth. So when it tried to mount rpool/exports, it failed. Then, iscsipool was unavailable, so the system failed to bootup completely. I was able to login to console as myself, but I had no home directory, so I su'd to root. I tried to change the mountpoints of localpool/backups/exports and so forth - but it failed. Filesystem is in use, or filesystem busy or something like that. (Because I logged in, obviously.) I tried to export localpool, and again failed. So I wanted some way to prevent localpool from importing or mounting next time, although I can't make it unmount or change mountpoints this time. rm /etc/zfs/zpool.cache ; init 6 This time, the system came up, and iscsipool was not imported (as expected.) But I was surprised - localpool was imported. Fortunately, this time the system mounted filesystems in the right order - rpool/exports was mounted under /exports, and I was able to login as myself, and export/import / change mountpoints of the localpool filesystems. One more reboot just to be sure, and voila, no problem. Point in question is - After I removed the zpool.cache file, I expected rpool to be the only pool imported upon reboot. That's not what I observed, and I was wondering how the system knew to import localpool? _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
