Tags.

yeah, having tags on the topics makes them better than pinning.

@tim_g said in Storage for On-site Backups:

Otherwise, unless you can get a direct 1gb or 10gb network connection, backup times will suck.

Just an FYI, this also may completely depend on your backup software too.

But if using a software backup appliance such as unitrends on a VM, you'd want to have the storage local to the Unitrends VM for example.

So when I first install XenServer and I "tick" thin provisioning, behind the scene it's making the drive ext, so I assume if I didn't choose thin provisioning it would have made it LVM?

This is all part of why I dislike unRAID. Not only do they offer literally nothing that I can tell of value, but they act like a bunch of normal features are special. They pretend that they are doing something special with KVM and Docker and RAID 4 - all things that you already have in equal or superior form, for free, with an enterprise Linux distro. Install Fedora for free, and you have a simpler, safer, more powerful alternative to unRAID that is only upsides, I think. More power, less effort, less cost, easier to support, easier to get support.

IMHO, dispersing the storage between the hosts and configuring data replication between them would be the best option.

Creating several tiers for the migration of your VMs is always nice to have - downtime strikes unexpectedly.

@r3dpand4 said in Configuring Multi-Resilient Volume with Storage Spaces:

Should be noted that any server running 1709 cannot be added to S2D pools as it stands currently since it's not considered production ready....

Correct. S2D is gone from non-GA WS2016.

https://docs.microsoft.com/en-us/windows-server/get-started/server-1709-relnotes

Storage Spaces Direct

Storage Spaces Direct is not included in Windows Server, version 1709. If you call Enable-ClusterStorageSpacesDirect or its alias Enable-ClusterS2D, on a server running Windows Server, version 1709, you will receive an error with the message "The requested operation is not supported". It is also not supported to introduce servers running Windows Server, version 1709 into a Windows Server 2016 Storage Spaces Direct deployment.

The implementation of an Azure Stack would be something to get our heads around for the time being.

Hopefully it is better than the actual Azure system!

It is Azure, same thing, but you have a physical node on-prem. You pay for the hardware, and you get Azure a little cheaper, but it's fully managed by them.

It's really only for remote places with bad bandwidth imho.

Think like, needing cloud from an 18-wheeler in a remote location.

This sounds like a crappy version of the AWS Snowball

Completely different.

This is like making your portion of the AWS cloud in-house, including the entire AWS stack.

Again, not too useful unless you are trying to bring the cloud to a remote location to avoid excessive latency or to somewhere the internet doesn't exist... like linking it to a satellite connection during a disaster or something.

There are other real uses, but that would be for bigger enterprises... for most SMBs, Azure Stack would never be a consideration.

@jimmy9008 said in What Is RAID 0? SAMIT Video:

I like the video; I'm not sure how helpful it is though.

Well, if you already know RAID 0. But lots of people don't, and I want to be complete.

I think it's definitely needed. Anyone who doesn't have any knowledge on the subject but is looking to learn will have a good resource in this.

Have you installed CMC? It should find it by scanning the subnet.

@matteo-nunziati So, CentOS 7 , EXT4, LVM with compression turned on.
After all, I'm using consumer / smb desktop hardware. From what I've read, ZFS would require more resources than I have available if I wanted dedupe. My storage box will only have 8 GB RAM.

Generally go XFS but even ext4 is good. ZFS requires something like 1gb per raw tb of storage but mostrly for raid/compression. It raises up to 5gb per tb if you want dedup.
So 8gb=8tb of raw (pre raid) storage.
ZFS is nice byt you usually can go w/out its features in smb

The memory is for dedupe. It needs very little for compression and RAID. Those use CPU, but not RAM (much).

No you are right 1gb is for dedup

I do this a lot 😉

@shuey said in Advice on building "storage servers" with two DL380 G7 servers:

The CDW rep said:

"Is it apple to apples or did xbyte use third party memory and drives? We are dell's largest partner so it should not be a large difference if truly apples to apples."

CDW might be the largest, but they aren't known for passing along good pricing, being very honest and they only deal in new, not refurb. So it is expected that their prices will be way higher.

xByte will use non-Dell parts, but keeps them under warranty. So it remains apples to apples. CDW is just panicking because they want the sale.

@travisdh1 said in NextCloud: Insuffienct Storage:

Which base OS is being used? Debian/Ubuntu or RedHat/CentOS/Fedora? Log files will be different between the two that I'd want to look at. Either way probably looking for the apache/httpd log.

Fedora -

Additional options: use something like Salt to create network mappings for the computers.

I am interested to hear about:

"Salt to create network mappings for the computers."

Since salt works only when minions connected, and for reason my NAS and windows clients loses the connections every 2-3 days and requires the user to re-input username/password (maybe related to Windows limtiation)

how will you effectively use salt for that purpose ? just put script to run at user login ? any other neat ways to do this ?

Salt is meant to run continuously. For example, mine run every 10 minutes or so to verify the environment. So if a mapped drive failed, it would be fixed again in a few minutes.

The same goes for GPO. It refreshes every 15 min I think by default.

Every 90 minutes with a 30 minute flux. So every 60-120 minutes for GPO.

Not quite the same as NFS 3 and NFS 4, but we intentionally use NFS 3 much of the time today even though NFS 4 is old.

This may be good for a fork...but why hang on to NFSv3 instead of stepping up to NFSv4??

Because the work differently and having the overhead of NFSv4 often does not make sense.

Can you give more detail?

They are very different protocols with a lot of different features. NFSv3 is much lighter than NFSv4.
