@scottalanmiller Or more if @scottalanmiller's family visits.

Fo sho!

My kids each hook up a laptop, phone, Nintendo Switch, Amazon Tablet, iPad, and possibly more like instantly.

Well I mean the iPads are going bye-bye with this recent announcement from Apple, no?

Yup. Xiaomi has a new tablet being announced THIS WEEK. I'm pretty excited. I hope that it is available quickly as I was about to buy an iPad for myself and this looks like a way better option. However, rumor is that no "mini" size is coming in the announcement this week 😞

@biggen : Something like procmon with thread profiling events enabled should give you an application's processor or disk usage over a period of time.

EDIT: Good example here

@biggen said in NVMe and RAID?:

But what about the server case itself? What models are you putting these components in? I'd probably do a tower for the initial build.

Pedestal: Silversone CS381.
Rack Chassis: We go barebones from a variety of vendors. Intel, TYAN, ASRock Rack, and others
Rack Chassis Standalone: Chenbro comes to mind. Silverstone also makes them. We've looked into iStar and Rosewill though never jumped on board.

@Pete-S said in Add 2.5" U.2 (NVMe) SSDs to custom build?:

Intel P4510

Yup that would work. Wish I could figure out a way to at least mount the U.2 drives in the 3.5" external drive bay since I don't need a 3.5" bay for anything else. ICY DOCK makes a twin 2.5" SATA drive bay that fits in a 3.5" bay, but they don't make a twin 2.5" U.2 NVMe drive bay that fits in the 3.5". I'm guessing the 2.5" U.2 needs either more spacing or better cooling than a standard 2.5" SATA SSD.

You don't want them in an external bay. Remember that these are PCIe bus connections so it makes sense to have short cables. The cables in the adapter above are probably 1.5 feet at the most.

U.2 drives are thicker than standard SSDs, usually 15mm (a little more than 1/2 inch). They get hotter than normal SSDs but nothing extreme. P4510 for instance is rated at 16W power consumption. Which is about twice as much as a 3.5" spinner. In a high powered rack server the drives stays cool but they're usually designed to have a generous amount of airflow through the case and over the drives.

PS. If it wasn't clear - U.2 drives have the same mechanical mount as 2.5" drives. So you can mount them in a 2.5" internal drive bay or in a 3.5" internal drive bay with adapters. You just can't put them in a hotswap drive bay or any drive bay that has an SATA or SAS backplane because it's electrically not the same.

@biggen said in Gluster and RAID question:

So your VMs are running off the Gluster?

Gluster is generally used for that, yes. Because backup storage rarely can leverage the advantages of Gluster, it just doesn't make sense. But for VMs, that's Gluster's bread and butter.

VMs really "never" should be running off of a SAN. That's exactly the least likely option to make sense.

We used it for automounted home directories for a while. It works well for that also.

@biggen said in Getting started with automated provisioning?:

I’m not sure the difference between a clone and a copy. I’ll look that up.

Clones are linked. Copies are discrete.

@Pete-S Ok, I went ahead and let the installer partition it using the defaults for LVM. Everything is working!

The installer creates a small primary partition and installs /boot to it. It then creates an extended partition with the remainder of the drive and slices up logicals out of that for the LVM. It puts “/“ in vg1 as “lv root” and puts /swap in vg1 as well as lv swap”.

I was not creating a /boot. Never have. I was just creating a primary for the “/“ and then saving some of it for an extended /swap. I’ve done this forever. It even works in a VM. I have no idea why I couldn’t get it to work on the physical machine.

https://mangolassi.it/topic/20143/spec-ing-a-new-computer-from-dell-or/

I think the VM could still be migrated so long as I detach the passthrough disks first, move those disks to a new host, migrate the VM to the new host, and then re-attach/passthrough the disks on the new host.

You can indeed. Not very practical but no technical barrier.

I wonder - can you create an NFS mount point in XenServer or XCP-NG? then just share that via loopback?

I don't really see the point of doing that? I had in mind an NFS share mounted directly in the VM. Simple, efficient (if you already have a NAS obviously)

@black3dynamite

It wasn’t cheap. But the host needed an upgrade, I was rocking an old 2 core i3 Ivy Bridge. It was time for an overhaul.

So I think I "may" have fixed it. I upped the logging level in Samba and noticed that it was a NTLM auth problem.

So I added ntlm auth = yes which allows NTLMv1 clients to connect in the smb.conf file.

SAMBA 4.5 changed the default method of NTLM to NTLMv2 clients only. Older clients that don't use NTLMv2 can't connect without changing this setting.

What a PITA that was to diagnose.

I just wanted to comment that Oracle is selling support for RHEL, without the name, under their product Oracle Linux.

Good example.
