Linux Read only file system ??

Linux Read only file system ??

2g00d4u ::

Danes se mi je pojavil en čuden problem. Na serverju imam nameščeno FC4 in danes kot začuda samba ne deluje. Ok grem pogledat in se samba ne restarta. Potem ugotovim da niti datoteke ne morem izbrisat niti ji ne morem spremeniti pravic vedno mi napiše, da je read only file system. Kako je lahko read only če do sedaj ni bil in sem prijavlen kot root. A se da to na kak način rešit ali samo reset servera pomaga??

Prosim če mi lahko kdo pomaga

Hvala

Leon

Kami ::

Kopiraj sem /etc/fstab najverjetneje maš tam narobe kaj nastavljeno.

Potem ko boš popravo, pa daš lepo mount -a :)

Btw brezveze bi blo zaj ročno umountat pa potem nazaj prav mountat, ker če neboš fstaba popravo, boš vedno bo rebootu spet moral popravit.

Zgodovina sprememb…

ok razumem to..samo nečesa ne razumem...server laufa 3 tedne nedotaknjen in se na kr lepem to zgodi...
pa fstab je menda čist ok... Pa tud pravice na datotekah so enake kot so bile...samo da ne morn nič poganjat ker je samo read only.

še kopija fstaba

po mojem samo reboot pomaga. Samo bi vseeno rad vedel zakaj se je to zgodilo oz. kako ukrepat da se to ne zgodi naslednič.

roscha ::

Z uptime poglej če je sistem v resnici 3 tedne gor. Lahko da je vmes zmanjkalo elektrike?
FSCK ni naredil svojega in je padel v "maintainance mode" (single user read only) ?

2g00d4u ::

Ok sedaj sem rebootal...pa se mi prvič tud ni zagnal...nek error... Kje lahko vidim errore ki jih izpiše kernel? Sistem je sigurno 3 tedne laufal, če sem natančen 23 dni...Prikloplen je na ups, tako da mu tud elektrike oz izpadu ni zmanjkalo. Ok čist mogoče da je pado v "maintainance mode", karkoli to pomeni. A se ga da potem rešit iz tega stanja, ali samo reboot pomaga?

Kami ::

Napiše errorje, bomo lažje pomagali (dmesg?).

roscha ::

reboot...

vsi logi so v /var/log

roscha ::

PŠT. Sistem za brezveze ne klecne. Mogoče imaš HW problem, vdor od zunaj ali malo verjetno problem z kernelom.


BTW Kater filesistem uporabljaš?

Ok to je zaj cel dmesg

Zaj po 2 rebootu vse dela tak kot je treba oz. ta irq12 me malo skrbi...Čist mogoče da bo kaj crknilo...Za vdor dvomim, ok lahko da samo malo verjetno.
Uporabljam pa EXT3 filesystem, kot je že iz loga razvidno
