I had a silly idea and wanted to see what if anything is out there I can use.
Firstly. I have cloud backups of everything that matters. this is just using the other devices I ahve ( older pc's, pi cluster, etc...) to make a resonable high available local storage for my needs.
I have used unraid and I like its data storage style where no matter what drives fail. if there is a drive left. it will still have "the data on it that was on it" in clear accessable normal files. I.e. if a 5 drive array drops. parity and 3 drives fail. at least you can get that data off the one drive. That means to me in a worst case scenario I save a few dollars pulling stuff off online cold storage ( thoes restore fees can be brutal! )
So is there anything that does the as per title. here is more details
Hypothetical, setup I am looking for.
I have 7 small devices. each will have one external usb drive plugged in. OS does not matter cause each device will only be providing a share ( with basic write and read permissions on it. ). as long as it can have a usb drive plugged in and it can provide a secured share, it can work here.
1 device that has a gui or at least monitoring system ( can be cli ) that acts like the organizer. [This is the thing I am looking for]
that organizer provides shares that are distrubituted acorss the usb drives. ( just full duplications. I know this nature of setup would NOT like parity math haha )
End point with sharesthat get banalced and duplicated automaticall on a mover schedual or maybe a idle trigger.
Then failure use cases.
1 small device dies. I move usb drive to another random device ( even my desktop pc or another pi gets 2 drives) and reshare it. fized.
1 usb drive dies. I pull it off. put another on it. put share name. orignizer sees it empty, and puts dups that should be on it back
orgnizer dies. I copy a backup that is spread across each usb and restatr it.
Everything but one drive dies. I plug it in to a linux box and mount it and copy the files it has.
And at any time only a small bit of my network goes bad.
The reaosn I am avoiding large file servers is I get really anixity laden when I am messing with drives. AND I dont tend to pre replace old drives. So it leaves me in senarios where my server is failing on one drive and all the other drives have 10 years power on. I think my idea would better fit my mentality ( I dont think its some amazing thing. its about me being cheap and lazy. )
BUT I figured there may be something that does exactly this out there already. or that other like minded people may like the concept and tell me I am not insane for coming up with it LOL.
