Dotaz: Nefunguje mi df a mount

[Jiri Pech]

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".

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

[vol0da]

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.

[Jiri Pech]

Skutecne /etc/mtab je prazdny. Ktere logy mam vystavit?

[Maude Lebowski]

Obavam se nejhorsiho (chyba v systemu). Co rikaji logy? dmesg? /proc/mounts, ty filesystemy se daji pouzivat?

[Jiri Pech]

Oddily jsou normalne pouzitelne.

/proc/mounts se zda v poradku:

lamc:~ # cat /proc/mounts
rootfs / rootfs rw 0 0
/dev/root / ext3 rw 0 0
proc /proc proc rw 0 0
sysfs /sys sysfs rw 0 0
devpts /dev/pts devpts rw 0 0
tmpfs /dev/shm tmpfs rw 0 0
/dev/sda1 /boot ext3 rw 0 0
/dev/sdb3 /home ext3 rw 0 0
/dev/sdb2 /tmp ext3 rw 0 0
/dev/sdb1 /usr ext3 rw 0 0
usbdevfs /proc/bus/usb usbdevfs rw 0 0
/dev/sr0 /media/usb-storage-20040223000005609:0:0:0 subfs ro,nosuid,nodev 0 0
