 Yeah, hello, I'm audible back there. All right. My name is Ajit and I work with red hat and today I'm going to talk about your application, which is actually Actually based on a file system called cluster of s which is currently used by red hat So cluster of s what what it is. It's a pretty simple user space file system You have your commodity hard commodity hard drives. You can build EXT for our kernel file systems like that and Over it you can create a cluster file system, which would be Distributed as well as highly available Using various modules like AFI on so so the main feature that I'm gonna hire you. I'm gonna discuss about today's geo-replication Which is gonna be something pretty interesting something new something You could use as an enterprise user or a common man who lives at home. So let's see Okay, it's asynchronous the replication as in say you have two volumes master and slave it replicates Things you have stored anything it could be a VM image. It could be a movie. It could be a file It could be anything just anything from master which is located at a part of say India to a US Just as simple as it as I say It could be used as disaster recovery Elements say something happened at your initial setup at your master setup You can reuse your slave setup slave slave data center to be replaced for For your use for your purpose Moving forward What are the actual challenges what are the actual problems that are being solved using geo-replication at use with Gluster FS If you are enterprise you'll hear these problems like yeah, yeah load is too high or I have a power outage at my data center or You know, it's too may too costly to maintain two data centers who are supposed who are supposed to be exactly same The server is down or you know things like that So these things are solved if you are solved using geo-replication if If you are an enterprise guy, so say I'm not enterprise guy. I just live at home. I'm normal person Still I can I use it? Yeah, of course. So say you are you are you are You are here in India and you have a cousin in US and you want to send pics or movies or anything Say your videos of your birthday You can still send it over to your friend and you need not take care of it You just keep putting your files as that as as you store and he'll also receive it we always keep working on different workstations and We need things to be synced up so you can still use it. You can have your things backup important things backed up So that whenever you need it you can reuse it from where you had backed up. All right, so How is it so much? Why is it such an important thing and why was it not in picture previously and why is it such an influential thing right now? initially it it the mechanism that was used used to use a file system crawl which used to detect the change and and used to figure out what are the difference differences between two Master and slave data and used to sink or sink over sink over the van but Okay, yeah, so the time taken was kind of more because it the check used to happen Across the van But now the now the things have changed and it uses journals which is which detects the Changes happening in constant time, which is like the IO happen and I know what IO happen and how to replicate it That's it and it's pretty useful. You can just try it at home. It's pretty simple to use any questions a Journal it logs things it logs. Ios happening on your file system cluster It it is used as it is by Geo application as a customer Any question any more questions? Yeah It doesn't use So we just for data transfers. Yes, we use arcing for creations we use RPC calls which create the files Pretty quickly Whereas if you if you use arcing as raw it will take much time So if just few questions that I had from my point of view is it useful for me? For me. Yes, it's useful because say it if your interface guy. Yes, it is fast Yes, it it's a 10x fast than the previous release that we have time up. Thank you
