Správa služeb hlavního města Prahy se potýká s následky kyberútoku. Hackerská skupina začala zveřejňovat na internetu některé z ukradených materiálů a vyzvala organizaci k vyjednávání. Ta zatím podrobnosti k případu sdělovat nechce. Případem se zabývá policie i Národní úřad pro kybernetickou a informační bezpečnost (NÚKIB).

Restart jsem nezkoušel protože je poškozen login, mám obavy že server nenaběhne a jeho provoz je kritický.
Přihlašuji se pomocí ssh.
V logu jsem nic nenašel jen chyby disku, ale myslím, že ty souvisí s poškozenými soubory ne se samotným HW.

Prosím o jakýkoliv nápad na řešení jak se zbavit chybných souborů
Děkuji za jakoukoliv přínosnou pomoc.
Ja si naopak myslim, ze mate HW problem, ktery s nejvetsi pravdepodobnosti zpusobuje problemy s filesystemem. Rozhodne bych se podival na podrobnosti ve SMARTu disku.
Tak si mount a dalsi utility nakopirujte z jineho stroje treba do /root/ a spoustejte je tam.
Soubory nejspis nemuzete smazat proto, ze se korenovy filesystem automaticky premountoval jako read-only po zaznamenani chyb.
Děkuji,
máte pravdu, opravdu je vadný druhý disk v raidu sdb2

Takže to bychom měli proč, nyní jsem tedy "rozbil" raid a zkontroloval jestli opravdu :)

vytvořil zálohy pomocí nakopírování mount do root jak říkáte, děkuji,
disky, tedy teď již jen sda2, je RW, do adresáře /bin můžu zapisovat/mazat, ale stále mě trápí ty nesmyslné práva, délky u výše zmiňovaných souborů a stále nevím jak se jich zbavit. Smazat stále nejdou, znovu zkouším mazat podle i-node. Potřeboval bych se jich zbavit před opravou raid, abych nekopíroval vadné soubory.
