So I’ll start with 10 TB, and I’ll increase it over time.
As for RAID5, I can’t change it, because it already has data, although I don’t like to lose two disks with so few physical disks.
Right now I just made again the request for the token to be sent to me, and it didn’t take more than two minutes. Yesterday I did it through Firefox and you can see that there was some problem.
I have another question about the bandwidth and DDNS allocation. If by assigning a bandwidth to the application, that bandwidth will only be exclusive to Storj? As for the DDNS, I have it configured in the router, do I still have to follow the installation process as indicated on the website without making any changes?
As for the caching, I think I will not use that resource for Storj.
The records are HGST He10, and I’ve had to replace some of them and nothing has ever happened to me. To avoid the corruption problems of the RAID, I think the P440 controller and the 4GB of cache take care of those possible problems.
I wish I could have it on a RAID 6, but it is a big waste of space, and now I only have 20 TB free in the whole RAID. The controller can do the migration online, as it can also do the band change, and you can tell it if you want it to do it fast or slow, with the aggravation that you can lose performance while it is doing the migration, or not lose performance if you tell it to do it slow.
As for the DDNS, as you say, I will skip that step because I have already configured it in the router for a long time.
Do you know anything about the attacks that the dedicated port for the node may receive? The router I am using is not the one provided by the ISPs, and normally it receives updates, but having this port open, it can be prone to attacks.
The good news is that with those HDDs the second image would apply. That still gives your array an over 40% chance of failing on a rebuild. And no amount of caching is going to protect you against a URE while one disk has already failed, since there is just not enough data available to recover from that. I know giving up 10TB sounds like a lot. But it’s a hell of a lot better than losing all your data. I hope you at least have solid backups and no business continuity relies on this system being up and running. You can do what you want of course but I just want you to take an informed risk if you choose to do so.
Attacks aren’t necessarily on ports, but on the software listening to that port. Of course nobody can promise that any software is bug free. So I can’t say much there. I trust Storj has done a good job to protect against attacks.
At the end I could solve the problem, and it is that in part 8 of the installation through Windows GUI, I did not incorporate my name DDNS:PORT. I deleted the application and the storj folder in C/ and when I reinstalled it, I incorporated the DDNS and everything worked correctly. I didn’t put in the DDNS because I thought that since the router already has it assigned, at this point it wasn’t necessary.
As for the satellites, I have already understood how they work, although I thought I should choose one by proximity, because I did not know how they work.
I was taking a look at the controller configuration to see if I could migrate to a RAID6, but I only get the option to go to a RAID0. Is it because there is not enough free space to give the option to migrate to a RAID6? Right now there is a 27.3 TB free space.
There is no specification that you cannot migrate to RAID 6.
I didn’t know those files changed so constantly. So it’s unfeasible to back up to the cloud, only me and RAID 5 are left in danger, even though I have all my trust in my beloved server. Thank you very much!
Sure you can go with your sample of 2. But mathematically speaking with the stated URE rate there is a 33% chance of surviving the first 2 rebuilds. Far from impossible, but by no means an indication that your array is more safe than what the numbers suggest.
I wouldn’t worry about the STORJ data too much. Yeah, it’d suck to be disqualified, but you can start a new node and the data is redundant on the network anyway. But you seem to be using this array for other stuff as well. Make sure you have reliable backups for all of that.
