fsck pada

[Jozef Drahovsky (FreeBSDcz)]

Ahojte

Stretol sa niekto s tym, ze na konkretnom disku
fsck padne a skonci s hlaskou "Segmentation fault"
Disk ide namontovat a data ide stiahnuť bez chyby, okrem jedneho suboru.
Ten subor (resample videa) bol vytvarani prave ked došlo k zákmitu 
napatia v seti a rebotu.
Rovnako fsck pada aj v 13.2 aj 14.0


# fsck /dev/ada1p1
** /dev/ada1p1
fsck: /dev/ada1p1: Segmentation fault

Zatial som nasiel len informaciu z roku 2022
https://cgit.FreeBSD.org/src/commit/?id=904347a00c1f9a29f3b17e6e676805036d2494f1

Má niekto nápad ako disk opraviť, inak ako reinicializaciou?
