Thanks for your comments so far. I'll try to put everything I know into this post now that I have signed up at the forums.
Solaris 10, update 8 Intel, 500G ZFS root mirror rpool. I recently received two 320G drives and realized from reading this list it would have been better if I would have done the install on the small drives but I didn't have them at the time. I added the two 320G drives and created tank mirror. I moved some data from other sources to the tank and then decided to go ahead and do a new install. In preparation for that I moved all the data I wanted to save onto the rpool mirror and then installed Solaris 10 update 8 again on the 320G drives. When my system rebooted after the installation, I saw for some reason it used my tank pool as root. I realize now since it was originally a root pool and had boot blocks this didn't help. Anyway I shut down, changed the boot order and then booted into my system. It paniced when trying to access the tank and instantly rebooted. I had to go through this several times until I caught a glimpse of one of the first messages: assertion failed: zvol_get_stats(os, nv) Here is what my system looks like when I boot into failsafe mode. # zpool import pool: rpool id: 16453600103421700325 state: ONLINE action: The pool can be imported using its name or numeric identifier. config: rpool ONLINE mirror ONLINE c0t2d0s0 ONLINE c0t3d0s0 ONLINE pool: tank id: 12861119534757646169 state: ONLINE action: The pool can be imported using its name or numeric identifier. config: tank ONLINE mirror ONLINE c0t0d0s0 ONLINE c0t1d0s0 ONLINE # zpool import tank cannot import 'tank': pool may be in use from other system use '-f' to import anyway When I do # zpool import -f tank I get a kernal panic and the screen flashes and the machine quickly reboots before I can see what's written, but I did see assertion failed: zvol_get_stats(os, nv) and there seems to be a patch 6801926 associated with it. I tried the following: 1. fmdump -ev. Either the command is not found when I bring my system up in the Solaris failsafe mode, or when the root pool which is ok gets mounted on /a the command is also not found. I did chroot /a /bin/sh and then the command is found but I get error messages about not having certain files available in /var, probably because I have /var on a separate filesystem. I do not know how to mount things as if the system came up normally and if I boot in the normal mode although it can import the root pool the tank pool was also a root pool at one time and it seems to mount it and then panic and reboot. I think it would be a lot easier to do whatever we can do if I could get the system to boot into normal mode without importing tank. Can anyone please explain in very clear and simple directions how to do that please? 2. Solaris 10 update 9 does boot but won't install, presumably because of not having a CD driver for my nvidia chipset, although the install does start it gives a message something like "the CD is not a Solaris OS CD".. I tried single user shell and it also panics when I zpool import -f tank. This is very discouraging because according to the Solaris 10 update 9 patch list, 6801926 is supposed to be preapplied. I don't understand why the update 8 DVD works on my system but update 9 doesn't. That is just weird. 3. Solaris 11 Express falls into maintenance mode and doesn't go any further. I get an error message something like bash: /usr/bin/hostname command not found, and I can't do anything useful. 4. OpenIndiana Server doesn't come all the way up. I get the Solaris 5.11 message and then it does nothing. 5. Milax falls into maintenance mode like Sol 11 Express and then panics when I try to import tank. I have Solaris on Sparc boxes available if it would help to do a net install or jumpstart. I have never done those and it looks complicated, although I think I may be able to get to the point in the u9 installer on my Intel box where it asks me whether I want to install from DVD etc. But I may be wrong, and anyway the single user shell in the u9 DVD also panics when I try to import tank so maybe that won't help. I have only 4 sata ports on this Intel box so I have to keep pulling cables to be able to boot from a DVD and then I won't have all my drives available. I cannot move these drives to any other box because they are consumer drives and my servers all have ultras. I have about 200G of data on the tank pool, about 100G or so I don't have anywhere else. I created this pool specifically to make a "safe place" to store data that I had accumulated over several years and didn't have organized yet. Can anyone PLEASE help me get this data back! Thank you.
