Dobry den,
v Turrisu mam SD kartu, kam si ukladam statiky vnstat, databaze Majordoma a pripadne dalsi zalohy, abych neopotreboval flash pamet routeru. Tento tyden v pondeli jsem vsak zjistil, ze Turris SD kartu vubec nevidi a v adresari /dev chybel soubor mmcblk0p1. Nepomahal restart, tak jsem musel uvest Turriska do tovarniho nastaveni a pak uz bylo vse OK.
Nejsem linuxak a trochu se v tom neorietuju. Zajimalo by me, jestli behem te doby, kdy SD karta nebyla namountovana, se statistiky, ktere ukladam do adresare /data, ktery je namapovany prave na SD kartu, ukladaly do adresare /data na flash pameti nebo do adresare /data na SD karte, co tam "nebyla".
Taky jsem si vsiml v systemovem logu nejake error hlasky, ktere jsem tam predtim nevidel:

Nemuze byt problem s SD kartou? Existuje nejaky chkdsk command v linuxu, abych zjistil, jestli je SD karta v poradku? Nemohlo se stat, ze kdyz se mi co 5 minut zapisuji statistiky na SD kartu, ktera tam nebyla videt, tak se data zapisovala do adresare /data, ktery byl v tu dobu ve flash pameti a ta se treba mohla tim zapisovanim opotrebit (nejsem schopny zjistit, jak dlouho trval tento nekonzistentni stav)?
