I added a header into the main topic list for that. But it is going to be later in the Advanced Topics, section. Oddly, I know of pretty much no standard Linux Administration tomes that cover DRBD. It's so core, very odd that it so often gets missed.

Could it be that most Linux Admin's don't know about it until they go searching for it? ...That's how I found out about it.

You would hope that the people writing the books would know, though!

Of interesting side note, the Linux md RAID system also implements Intel Matrix RAID and DDF (Disk Data Format) software RAID formats commonly used by consumer FakeRAID systems. Because of this, Linux md can sometimes convert FakeRAID into enterprise md RAID if you really know what you are doing 🙂

And by checking, he means learning and just happening to find it.

Red Hat has introduced a new technology, called Stratis, that is a layer combining Linux' existing LVM2 technology and the existing XFS filesystem and merging them together to be managed as a single unit with best practices automatically applied. It's not new per se but takes best of breed existing technologies and puts them together to feel and act more like their more modern competition.

User of CentOS and Ubuntu servers myself. Mint is still top go-to for desktop, though there are interesting alternatives like ElementaryOS.

Linux is not always easy to learn, I just forget everything if it's not regularly used, especially CLI with their bazillion switches that no mere mortal can ever memorize. And moving between different distros where commands don't work exactly the same, Aptitude and Yum, etc.

Cool, but always challenging.

@scottalanmiller Ah, yes. That would be a more efficient way of doing it. I was too excited from finally gaining some understanding of mount point concepts, I didn't think though the best way to move the data. 🙂

@Dashrender said in Linux: Creating a Filesystem:

I'm assuming LVM will be covered separately - I'm trying to understand what it's purpose is versus just using mkfs.

It will be. And it is unrelated. mkfs and lvm do totally different things. Neither replaces the other in any way.

I've always just used -h for human readable. I never realized -m would give you the MB size.

I have the "advantage" of having learned this stuff before the human readable flag was added 😉

@DustinB3403 said in Linux: Checking Filesystem Usage with df:

Will there be a topic on "managing inode in linux"

Yes, but it is going to go into an "Advanced Topics" section. Just as LVM and MD will have high level "normal" admin sections and eventually delve much deeper in advanced sections. I want to cover everything in a "normal admin" capacity like you would learn from the RHCE up front. Then go back and cover the nitty gritty details that other admin books don't. So it will basically take two passes but the hope is that the first pass will take you from "starting point" to "competent Linux Admin" then the second part will go where normal admin guides don't tread.

@tonyshowoff said in Linux: Zip and 7Zip:

Sorry if this was mentioned but I didn't see it directly mentioned for clarity:

If your compression is unavailable directly in tar (-J being essentially 7zip, my favourite), you can tar it first (without compression) and then compress the tar, this maintains both Unix metadata and also gives the benefit.

Also, if you compress something already compressed you won't get the best benefit, at least not when it comes to using something as powerful as LZMA/7zip.

I believe that that is mentioned in the tar article.

It doesn't update as "new" when I just update the list. Only if I comment on the thread.

@Dashrender said in From Windows to UNIX: Monolithic to Modular Design:

I suppose it's less of an issue as well, since Linux Distros are free, you just have another VM running the other software.
Windows, you'd have the Windows tax.

Exactly. A VM or a container or an application jail. Lots of options for mediation if you want the conflicting packages.

Thanks!
