    Dotaz: Nefunguje mi df a mount

    6.10.2004 14:49 Jiri Pech | skóre: 6 | blog: Pedagoguv_blog | České Budějovice
    Nefunguje mi df a mount
    Přečteno: 471×
    Pouzivem SUSE 9.1 a po nejake dobe behu (radove dny) mi prestane fungovat prikaz df a mount (samostatne zapsany mount pro vypis pripojenych zarizeni)

    lamc:/ # df

    df: cannot read table of mounted filesystems: No such file or directory

    mount nevypise proste nic. Pokud pocitac restartuji (coz ale nemohu delat moc cast) nejakou dobu opet vse funguje.

    Moje /etc/fstab: (kraceno)

    /dev/sda3 / ext3 defaults 1 1

    /dev/sda1 /boot ext3 defaults 1 2

    /dev/sdb3 /home ext3 defaults 1 2

    /dev/sdb2 /tmp ext3 defaults 1 2

    /dev/sdb1 /usr ext3 defaults 1 2

    /dev/sda2 swap swap pri=42 0 0

    devpts /dev/pts devpts mode=0620,gid=5 0 0

    proc /proc proc defaults 0 0

    Dekuji za kazdou odpoved, zejmena takovou, ktera mi pomuze. Prosim neposilejte rady typu "man df".

    Odpovědi

    To vypadá, jako by ti mizel /etc/mtab. Ale proč by měl mizet, to netuším.

    Avsak v pripade zmiznutia /etc/mtab by mount aj nadalej vypisoval udaje z /proc/mounts. Takze to vyzera, ze tych problemov tam bude viacej. Skuste pozriet logy, pripadne ich niekde umiestnit a dat na ne link.

    Oddily jsou normalne pouzitelne.

    /proc/mounts se zda v poradku:
