I am a long time Solaris user that tried out Linux for a couple of years,

I've been running Ubuntu on the same machine since 18.10, updating to each
release in-place, with no issues. Currently on 20.10. An excellent
Debian(-based) OS stability primer is here
<https://wiki.debian.org/DontBreakDebian>. If you follow that and ask
questions at AskUbuntu and Reddit you shouldn't have showstopper problems.
At the end I switched to Ubuntu 2020.10 hoping it would be more stable. It
was not.
Another problem is that OpenZFS v0.8.4 renders Solaris 11.3 disks unusable.
Disappointing, but not unexpected given that Solaris ZFS and OpenZFS are 2
different and independent ZFS implementations.
Try this:
-Create a ZFS disk in Solaris 11.3 (using zpool version 28, and zfs
version 5)
-Import the disk into Ubuntu 2020.10 using OpenZFS v0.8.4
-Copy data to the zpool using Linux zfs send recv
-Import the zpool back into Solaris 11.3 - This will fail. Solaris says
the disk is UNAVAIL and I need to use a backup to restore data.
So if you use OpenZFS to import a zpool, chances are you cannot import the
disk back into Solaris.
Because of all these problems I have now tried the OpenIndiana 2020.10
LiveDVD and I liked it. The splash screen says it is OI "2020.04". It maybe
should be changed to "2020.10"? Before I migrate off Linux to OI, I have
some questions I hope I can get help with?
1) I boot Win10 which is installed using UEFI. According the OI manual, OI
does not support UEFI.
http://docs.openindiana.org/handbook/getting-started/#booting-the-hipster-installer
So I should not install BIOS OI and UEFI W10 for dualbooting on the same
disk. I learned this the hard way. I had a Win10 and Solaris 11.2 dual
booting install, on the same disk using BIOS, i.e. MBR disk. Then an W10
update silently changed the disk to UEFI (GPT disk), and Solaris 11.2 was
still on MBR. So I could boot W10, but not boot Solaris. It took me a long
time to figure out why Solaris would not boot. I had to reinstall Solaris
using UEFI.
I think dual booting creates far more problems than it solves, and avoid it
my personal setups. I definitely do not think having dual booting an MBR
and UEFI OS is a good idea.
To solve my problem of BIOS os and UEFI os, I wonder if this might work: I
remove all disks except one, and install Win10 using UEFI. Then I remove
all disks, and insert another disk to which I install BIOS OpenIndiana.
Then I insert all disks, and when I boot my PC, I choose which OS to boot
from the disk boot menu by pressing F11. Do you think this could be a way
to have both BIOS OpenIndiana and UEFI Win10 on my PC, but on different
disks? I have read that you should not install BIOS and UEFI oses on the
same PC,
Sounds like you just answered your own question :P
even on the different disks - but I dont know why. I cannot find
information on this. But if I choose the different disks to boot in the
boot menu, this could work? Anyone know?
Such a setup is neither robust nor reliable, nor were PC BIOSes engineered
or tested for it. You're welcome to try it, but you'll be in unsupported
waters.
(BTW, I have a WARNING! If you boot Win10 install usb and only look at the
different disks in your PC, i.e. check the sizes of the disks, and then
exit without doing anything - this will mess up your ZFS disks. W10 install
software will mess up disks that are not NTFS. ZFS is something new, so
Win10 install software will overwrite the ZFS disks even scanning the ZFS
disks. If you do get your ZFS disks messed up this way, I have heard that
you can try to import the zpool and scrub it, and it might solve this mess.
Another way to solve this problem, is to remove all non ntfs disks from
your system before installing Win10).
See my previous warning about dual booting. I would never expose a ZFS disk
to Windows and generally do not expose disks to OSes that lack 1st party
support the filesystems on them. It's easy and affordable enough to get a
used, good condition Core 2nd gen or later x86-64 desktop on my end that
dual booting just isn't something I have to futz with.
2) Does OI support Sunray? (Solaris 11.4 does not support Sunray)
3) Graphics. I have a Geforce GTX 1070 Ti. On a UEFI installed Solaris
11.3, it is not possible to install the latest Nvidia 1070 Ti driver
because the driver explicitly requires a BIOS Solaris installation. To
install GTX 1070 Ti, you must install Solaris 11.3 as BIOS, and not UEFI.
If you have UEFI, there are no GTX 1070 Ti driver at all. You need to use
VESA driver.
The GTX 1070 Ti driver is certified for Solaris, but can the GTX 1070 Ti
driver be installed on OI, as OI is a Solarish derivative?
I wouldn't expect that to be the case as Solaris and Illumos have diverged
significantly since Illumos continued OpenSolaris.
