Synology SHR Migration on the DS1621XS+ NAS

[Music] hello guys and welcome back and today i want to carry on looking at synology nas now a number of you have been looking at the brand new ds-1621 xs plus along with a lot of other bigger large-scale synology nas solutions but one of the biggest downfalls of some of those bigger nas devices is that it doesn't feature synology hybrid raid otherwise known as shr shr is synology's own proprietary raid system that allows you to mix and match drives which of course on day one you'd never do on day one you're never going to put 3 tb and 10 tb and 6dbs you're not going to do that but later on in your device's lifespan you may well wish to you know invest in larger hard drives three four years down the line maybe you see a black friday deal and you're starting to run out of space so you want to buy bigger drives but traditional hard drive raids cannot allow larger hard disks if you you know had in this case for example we're looking at here if this was a raid 5 and if you had these are 3tb wd red hard drives if you had three of these three tvs and you introduced a 10 tb drive the system would only see three tv it would only classify the driver's three tb if you introduced a 3 tb drive and populated the other three base with 10 tv drives in a traditional raid it's only going to see them as 3tb the benefits of shr is that it looks at the total overall capacity of the drives and make sure that there's always one disk of parity available that covers the largest drive and then after that you can mix and match whatever drives you want so if you were to introduce three 10 tbs in this system it would still have 10 tb of redundancy but it would introduce 20 terabytes of data and that's kind of the big benefit of shr the other benefits of shr such as the ability to expand to the raid a great deal easier than you can with raid 5 and rate 6 and the fact that this particular kind of raid is very portable within synology now systems is one of the main reasons that a number of you were a little bit gutted the the xs series such as the ds1621 xs plus do not feature shr so what i'm going to be doing in today's video is i'm taking an shr this is in a ds420 plus and again this is a standard shr one disc um failure so in other words one disc fault tolerance or safety net and i'm going to move this raid into the ds1621xs a system that is not supposed to support shr you can't even select it at boot and what we're going to see is can we port this over i've done this test before in the past moving an shrine to an excess and it was successful but that was two years ago so right now i'm going in as blind as you are so i just wanted to show you guys firstly that this is indeed an shr inside this ds420 plus and that this is indeed the same shr that we're going to be moving over to the other system so if we go into the file station we can make sure to see the data that's inside we've got all the files from our plex media server uh video that we did around about a month ago we've got lots of data inside here lots of stuff to play with there is data on these disks and this is on a volume on the shr storage pool so what i'm going to do is shut this system down and then once it's shut down and we've allowed a couple of minutes to ensure that the discs have finished spinning always make sure that just because you turn the system off doesn't stop the drives automatically they need to organically and naturally spin down after that we're going to move over to the studio area i'm just on the other side of the office now and i'm going to take all four of those drives out of the 420 on camera and put them into the ds1621xs a non-shr system and then we're going to boot that nas up and see what happens so let's make our way to the studio okay guys so we've powered down the ds420 plus and we're gonna move these four drives into this six bay nas of course this is the six bay so we don't need all of the base we're gonna reinsert two of those empty bays there if you look in the background you can see all six of the drives i've pulled out of this so it did have the software on board if we insert that back in there we can then start installing the brand new drives i'm sorry about the sound quality i've left my mic set up over there from earlier on so this is kind of like the raw audio feed so i apologize in advance for the sound quality but to be honest this is fairly rudimentary and i'm pretty sure the majority of you are going to skip past this point anyway as i mentioned earlier on i have run um this kind of transfer once before i did it at the launch of the ds3018xs plus we moved some drives over from a ds916 now it was a couple of years ago and it was successful but that said you never know what happens with solidity and dsm and this is a brand new unit so better the high risk throw away data then you start risking your own important data now we have done a lot of testing of this nas device already we've done 10 gbe and ssd caching tests we've done plex and video station tests we did a windows 10 virtual machine installation guide we've done a software overview and i think we're up to four comparisons between this device and other synology nozzes as well as comparisons between this and a couple of high-tier qnaps i'm hoping those videos have already been published um i might make this video live a little bit sooner because i think a number of you are going to be upgrading to this device and you may you know purchase some of the older generation 918 um or maybe the 9116 or even some of the five and um 8k devices so there's a chance that what you're looking to do right now is to upgrade to a device like this which would make a lot of sense so no doubt you are interested to know whether your synology hybrid raid storage pool will be visible on this device let's get that in there it's kind of lucky these clips are pretty similar put them in there and we've got the final tray and the final drive and what we'll do when i've got this drive inside we're going to power this device up and then from there we're going to make our way back over to that screen over there and show exactly what happens when the device powers up sorry drop the tray there's a lot of stuff going here on screen and again i do apologize for the sound quality either you're seeing here um or hearing here even um just because it's easier to just do this like this and leave the mic set up over there in the studio in the office so there we go we've got all of our drives inside we've got two blanks and we've got that shr ported over physically so the only thing left to do is click power that's the fan kicking in for the first time and what i'm going to do is give it a couple of minutes and make my way over to the office over there let's make our way to the screen right so we've booted up our ds1621xs plus as you can see there in the background that was the ds420 it's still powered down from earlier and as we see this new nas is indeed migratable there it is there the ds1621 xs plus already booted up and it's on the ip15115 so it's a different ip to what the 420 was on but i believe because of dhcp you don't have to worry about that so let's double click and look at our migration options so we can take a little look at this bad boy and go through here it may ask us to download dsm again for the first time as you can see it has recognized that it is indeed a ds420 and that we can migrate this data over now this is slightly different to using some of these migration assistant tool that allows you to migrate data between two fully populated nozzes this is transferring data over from the same disks in one as to the other so let's click migrate we can choose whether we want to completely reinstall the synology nas and keep my data or keep the data in most of the settings now in this case we want to keep those settings so let's go ahead and see what happens um right now we can go ahead and click install and it's going to go ahead and download dsm 6.2 for this nas even though there is already dsm 6.2 on the the internal rom and we're going to fast forward to the completion of the installation of disk station manager on the ds162 and xs plus to see if our data and indeed our synology hybrid raid is still maintained okay so our nas has completely installed dsm and has rebooted as you can see here on screen so let's log into this nas for the first time our credentials should remain exactly the same because of the migration we can go ahead and skip that and we can see here straight away it is saying that we are on a ds420 because that is the name that we gave the server but of course this isn't a ds420 if we go into the control panel it should tell us straight away that this is a ds1621 xs plus let's go into the info center and boom the ds1621xs plus with our eight gig of memory it's all visibly available there and the name of the previous server is still there and i know it seems like i'm elongating it but we want to know that all the data is intact we can see all of our data there all of the folders that we looked at earlier on all of the basic stuff that wasn't in in those other folders even the dates the files it still maintained the original modification dates of all of that data and of course finally what we want to see is do we have our synology hybrid raid as we can see here we've got the storage pool we go into that storage pool and boom synology hybrid raid on our ds1621x plus we were able to migrate this over it's exactly the same drives it's still those three tv drives and of course there's a couple of ssds in there that we've got inside the caching base of this nas we might take advantage of in the future video but i can say that this video has been a success we've got our btr fs on our brand new ds1621xs plus which is not supposed to support shr because they do maintain s hr although it's very very good for home and small nas utilization a lot of business users do prefer ext4 so you can kind of understand the logic but i know a number of you have still a bit sore about the lack of shr one caviar i will add right now at the end of this video and probably should have uh started the video with this shr as much as i love it and as much as you love it was not intended for this device so if you are using an shr on a device that is not intended to be used for shr you can't guarantee the stability and synology themselves will likely tell you that you are using an unsupported configuration i don't know how true that is just looking at what we see here but i know synology is a brand that plays support and plays um supported compatibility and configurations very much down the line and what you're doing here may may not be stable so what i would strongly recommend just to be on the safe side and again this is not based on anything it's just gut instinct make sure you've got your backups in place have usb backups in place have active backup suite installed and create that multi-tiered backup strategy and ultimately make sure that you've got sufficient layers of backup that if something does go wrong with this you've got that safety net but thank you so much for watching i hope you guys have enjoyed this video and found it helpful do click like if you did enjoy click subscribe if you want to learn more and i will see you next time
