Máš pravdu, točivej disk mám asi 10 let a do loňského jara byl bezproblémový. Dokonce je možné, že problémy s ním byly spíš kvůli výpadkům napájení díky "upečenému" akumulátoru v UPS (kvůli vyšší teplotě okolí). Tak jako tak jsem si loni koupil nový desktop a ze starého udělal "server". Tzn. z původního serveru nezbylo nic kromě bedny a točivého disku. Ten tam mám už jen do počtu, je plně zastavený a montuju ho ručně jen v nouzi. Kvůli vibracím jsem ho nahradil za SSD, které je po 13 měsících nepoužitelné, takže reklamace. OS je taky čistá instalace.

Cílem této diskuze má být potvrzení nebo vyvrácení, že za problémy není jen chyba HW disku, ale i moje nastavení fstab, NFS, atd. Nějakou dobu jsem třeba používal 'soft' parametr pro NFS mount, o kterém jsem se později dočetl, že může způsobit silent data corruption.

Co tohle přesně znamená?

V rescue konzoli jsem párkrát skončil, nejspíš kvůli výpadku napájení. Root FS je většinou OK. Fstab upravuji právě kvůli dlouhým timeoutům, protože na vadný disk mám ještě několik bind-mountů a na to čeká asi 5 služeb a já nemám nervy čekat dlouhé minuty, jestli/až komp nabootuje nebo ne.

Jinak poslední výpis ze smartctl:
