sixwheeledbeastSeems my N900 uSD card has gone read only, what lifespan would you normally expect from them?21:02
KotCzarnydepends on flash cells wear21:05
KotCzarnyi managed to make my 128gb samsung evo+ gone ro without much use long time ago21:06
KotCzarnywasnt even full in 3/421:06
KotCzarnyif firmware is braindead it can make card ro as soon as it runs out of spare blocks21:06
sixwheeledbeastI have my swap on it...21:16
sixwheeledbeastbut that seems to work21:17
KotCzarnyit all depends how full was it, how much free space was used for wear levelling, and how smart wear levelling itself was21:19
joergand how reliably the power supply would support the uSD controller to finish its thing whatever that is (page erase, reflash, internal bookkeeping metadata persistent storage) before the supply goes down21:48
joergalso not mounting noatime,nodiratime(?) is an obvious killer to any flash storage that is formatted to a filesystem that has atime for its dirs/files(/inodes)21:50
KotCzarnyjournal isnt helping neither21:52
joergnot when kept on the flash storage. You *may* keep the journal metadata on a separate different volume/location21:54
KotCzarnywhich isnt obviously happening in swb's scenario21:55
