Hi All,
this weekend i will upgrade our main server from snv_111b to snv_151a
(Solaris 11 express). This will not really be an upgrade, but a new
installation.
I tested the new system on identical hardware (except for the data
pool) and installed it on an external USB disk, which i can simply
plug into the old server and boot from it. I did a quick test and the
new system boots ok on the old server.
You should try asking on zfs-discuss.
My questions is about our 5 TB data pool:
* Is there any risk in upgrading zpool and zfs?
I'm not aware of any and I've done quite a lot of upgrades.
* Do the pool / datasets have to be offline while upgrading?
No.
* How long will it probably take?
Almost instant.
* What, if power fails during the upgrade?
It's a tiny window for error, but as I said above, zfs-discuss is a
better list to ask.
Of course, i have a backup of the data pool, but i have not yet
rehearsed a complete restore, so i want to keep risk at a minimum.
Comparing the old and new zpool capabilities i saw:
16 stmf property support
Do i need this for COMSTAR iscsi?
Asides from new capabilities, have there also been enhancements of the
existing ones?
Yes, lots of bugs and performance niggles have been fixed.
