немного о надежности reiser4

в эти выходные я прикручивал Software Suspend 2, и мне приходилось много раз перезагружать машину reset’ом, т.к. были кофнликты с nvidia-вскими драйверами. итог оказался плачевным :

недолго думая, я загрузился с другого винчестера, провел fsck.reiser4:

1 fatal corruptions were detected in FileSystem. Run with --build-fs option to fix them.

ну ладно, мы люди не гордые, делаем fsck.reiser4 —build-fs /dev/hdb6 :
