[pso] pso Digest, Vol 30, Issue 5

[Stefan Cristian]

Salut,

Am reusit sa folosesc netconsole si am descoperit si de ce imi aparea Oops la functia submit_bio(). Mersi.
Am niste intrebari referitoare la programul de test:
1. Exista optiunea INTERNAL_TESTING. Vad ca daca este setata se foloseste doar sectorul 0 pentru testare, iar by default ea este setata. Este asa si pe server?
        Aici poate fi si o greaseala deoarece este setata asa:
            #define INTERNAL_TESTING 0
        si se verifica daca este definita asa:
            #ifdef INTERNAL_TESTING 
        mi se pare mai logic sa fie asa:
           #if INTERNAL_TESTING /* in cazul asta testul ar fi putin diferit */
2. In partea "TEST OPS" imi apare din cand in cand mesajul "failed: success" la testul simple compare. De obicei o singura data si nu apare mereu. De unde poate sa provina si de ce are caracterul asta aleator?
3. In partea "TEST MIRROR" imi apare mesajul "failed: Bad file descriptor" la toate testele de write si check crc. Cand trece la testele de read am success la toate. De ce imi da eroarea asta. Macar un hint :) sau vreo idee ?


Mersi
Stefan Cristian

Salut,

Uite un mesaj mai vechi pe tema asta [1]. E util sa pornesti o consola
in masina gazda care sa pastreze toate mesajele de la kernel (la un
crash, nu mai poti derula in sus in masina virtuala).
