What's to say? Check my personal website for a touch more detail, if you want to. I've been a professional UNIX/network sysadmin since 1991, and currently sysadmin free software professionally through my own little company. A long time ago, I and a co-author wrote "Building Linux and OpenBSD Firewalls" (Wiley, 2000). That's it.

If it's virtualised, my comments don't apply; but if it's merely containerised, see eg serverfault.com/questions/446289/… - you usually can't set the clock inside a container. Yet Another Reason why containers are not a cheap substitute for virtualisation, no matter how much the container sellers pretend that they are.

Drop the -s flag to ntpdate, for a start: we'd like to see the output, and forcibly sending it to syslog isn't the best way of doing that! It may be, for example, that ntpd is running, in which case ntpdate won't fix the clock and ntpd won't fix it because you're running without -g and the clock's two hours wrong. Only more output can help us isolate these issues!

comment 3ware array limited to 6TB in linux
Can you cut-and-paste into your question the output of parted -l? Also I, too, am suspicious that it's sdb, rather than eg sdb1, that's showing up as 6TB. I don't understand where sdb has come from, because you use tw-cli to show us the underlying device. Is it possible that you have created an 11TB logical volume, inside which is a logical drive - that the OS maps to sdb - which is only 6TB?

You told us you can't do it; what you showed us is the largest-possible success. We'd like you to show us it failing; the detail of the failure often sheds light on the nature of the problem.

Ben: +1 from me on both question (a textbook well-written one, for my money) and for coming back to post your own answer when you'd run the problem to ground. This may help any number of people in the future - thank you!

Can you show us an attempt to make a bigger partition, and how it fails?

Around these parts, RAID-6 or RAID-10 finds much more favour. We've just seen waaaay too many second-drive failures to be happy with -5. Also, don't forget RAID isn't a backup, and you need those, too. Also also, make sure you're constantly monitoring the state of the underlying hardware, so you find out about single drive failures and fix them before they become array-failure issues.
