XenServer: Backup & Replication

@FATeknollogee said in XenServer: Backup & Replication:
@travisdh1 Since the current suggestion from folks like @scottalanmiller is to have (and use) a single large array (RAID 5 or 10) for XS o/s & VM storage, why would slot population be a concern?
Five SSD bays is still pretty small. Even with 1TB drives, that's only 4TB usable. Often a limitation.

@scottalanmiller If one used your method of one large array, what is the advantage of using a 64GB USB stick? Just seems like your adding more complication?

It's to prevent updates (or something similar) from destroying your XS installation.
It's also a best practice to separate VDI/VM storage from the XS boot files.

Rapid restore, ability to image, ability to flip back and forth between versions.... and some platforms like ESXi can't do the single array without the USB/SD approach.

@DustinB3403 What actions have you taken with regards to logs been written to USB?
That is still up in the air, I've been working to get a good, searchable solution in place and haven't been able to complete anything. Up until now logging has gone directly to the USB without issue.
@BRRABill @DustinB3403 What do both of you plan to do regarding "logging + USB"?

@scottalanmiller What do you prefer: one large array-[XS o/s + VMs] or USB (aka small SSD or HDD)-[XS o/s] + large array-[VMs] ??

When feasible, SD card for hypervisor and RAID array for VMs is ideal. But SD installation causes a lot of headaches for people that either have hardware that doesn't support it easily and/or aren't comfortable with getting logging pointed somewhere other than the SD card. You have to adjust the write behaviour manually or it will not likely be properly reliable. In which case, install to the main array becomes the better approach.

@scottalanmiller Thank for clearing that up.
Why can't we get a simple & concise guide to external logging?

Because XS isn't up and running in the NTG lab yet and no one else is actively working on it to completion.

Well, I am.
But can I borrow your brain for the next few days, haha.

Still working on it.
My goal is to get it to boot off USB, log externally, and write nothing to the USB.

Go for it. First thing we need to do is test those new files.

OK, when I get in today, I'll look at the logging mechanisms, and post to the other thread I have going.

Create a clean thread, should be easier to follow.

Will do.
What was the resolution with your thread. Didn't you post something about this like last week?
-
@BRRABill I did, the solution I was looking at I never got to complete.

@BRRABill @DustinB3403 What's the latest info/news/update?

Oh wow this topic, I got graylog working for the log rotation from my hosts.
Use Xen Orchestra as your backup appliance.
-
@DustinB3403 No more logs written to your USB, 100% logs are going to graylog?
-
@FATeknollogee Yep.
