RT87 Posted November 27, 2022 Share Posted November 27, 2022 Hi, I changed my pool drive from an internal SATA conncetion to an external (SATA case plugged in as regular USB; I know it's not exactly "recommended" to do so). Now it doesn't recognize the disk since apparently the UUID has changed (I assume the SATA case transmits the ID of the controller chip or similar). Can I explicitly tell UNRAID to recognize this drive as the one that has been in that exact position? I.e. by manually changing the UUID mapping? Alternatively, how can I resolve this situation without compromising my pool? Best and thanks Richard Quote Link to comment
JorgeB Posted November 27, 2022 Share Posted November 27, 2022 Is this a single drive pool? Quote Link to comment
RT87 Posted November 27, 2022 Author Share Posted November 27, 2022 the pool is basically only this drive (no second drive, neither parity nor regular), if that is what you mean Quote Link to comment
JorgeB Posted November 27, 2022 Share Posted November 27, 2022 There's no parity drive for pools, assuming you still mean a pool and not the array you can fix that by unassigning the pool device, start array, stop array, re-assign the device, start array. Note that some USB bridges are not transparent, i.e., it won't detect the old partition, if that happens don't format. Quote Link to comment
RT87 Posted November 27, 2022 Author Share Posted November 27, 2022 (edited) sry, Ich meant "cache pool" (which to my knowledge have parties or at least redundancy, although I haven't used that so far) Does your answer still apply? Because I can start the array, even though the next to the cache disk it says "Wrong", but I am unsure of what will be the result... Edited November 27, 2022 by RT87 Quote Link to comment

RT87 Posted November 28, 2022 Author Share Posted November 28, 2022 nope, not the regular array :)! Thanks for your help, I'll try! Quote Link to comment
RT87 Posted November 28, 2022 Author Share Posted November 28, 2022 okay, so.... I cannot start the array without the disk, i.e. "Missing", and when I start it using the correct disk (although not recognized), it says "Unmountable: No pool uuid". Quote Link to comment

RT87 Posted November 28, 2022 Author Share Posted November 28, 2022 ok, that at least worked worked in starting the array with the disk, but now it indeed says "unmountable: wrong or no filesystem" Quote Link to comment

RT87 Posted November 28, 2022 Author Share Posted November 28, 2022 That's the only option? (sry!) Quote Link to comment
JorgeB Posted November 28, 2022 Share Posted November 28, 2022 That or reformat the pool, of course all there would be deleted. Quote Link to comment
RT87 Posted November 28, 2022 Author Share Posted November 28, 2022 If I have another drive which could serve as cache (which incidentally I do), I assume I could just copy the data and use that drive (after proper init), correct? Quote Link to comment
RT87 Posted November 28, 2022 Author Share Posted November 28, 2022 okay, thank you very much, I will try switching the disks, I think in my particular case that is probably the better method. Quote Link to comment
RT87 Posted December 5, 2022 Author Share Posted December 5, 2022 btw: that worked flawlessly 1 Quote Link to comment
