    Hey everyone, not sure this is the right place to post this, please let me know if it isn't this morning my server began having some trouble, I dont really know where to look, but Ive seen some threads that point me in the right direction;


    Code:
    root@mercury [~]# touch test
    touch: cannot touch `test': Read-only file system
    root@mercury [~]#
    Does't matter where in the system I try, tmp, home, anywhere it gives me an error saying its a read-only file system.

    The datacenter rebooted the server and ran fsck.


    Code:
    root@mercury [~]# smartctl -H /dev/sda
    smartctl version 5.38 [i686-redhat-linux-gnu] Copyright (C) 2002-8 Bruce Allen
    Home page is http://smartmontools.sourceforge.net/
    
    === START OF READ SMART DATA SECTION ===
    SMART overall-health self-assessment test result: PASSED
    Please note the following marginal Attributes:

    root@mercury [~]#
    I looked at this thread in particular as it is the same as my current problem; http://forums.cpanel.net/f5/read-only-file-system-23726.html

    Code:
    root@mercury [~]# /scripts/securetmp
    Would you like to secure /tmp & /var/tmp at boot time? (y/n) y
    Would you like to secure /tmp & /var/tmp now? (y/n) y
    install: cannot remove `/etc/init.d/securetmp': Read-only file system
    install: cannot remove `/etc/rc.d/init.d/securetmp': Read-only file system
    Unable to update /etc/rc.d/rc.local
    root@mercury [~]#
    
    When I got to the above step I got stuck.

    I also tried this; Zen Cart Support - View Single Post - Can't create/write to file '/tmp/ (Errcode: 30)

    to no avail I get stuck here:
    Code:
    root@mercury [/var/log/httpd]# /bin/rm -fv /usr/tmpDSK
    /bin/rm: cannot remove `/usr/tmpDSK': Read-only file system
    root@mercury [/var/log/httpd]#
    
    Also if any of this helps; Ive seen it on a few other threads;

    Code:
    root@mercury [~]# mount -l
    /dev/sda3 on / type ext3 (rw,usrquota) [/]
    proc on /proc type proc (rw)
    sysfs on /sys type sysfs (rw)
    devpts on /dev/pts type devpts (rw,gid=5,mode=620)
    /dev/sda1 on /boot type ext3 (rw) [/boot]
    tmpfs on /dev/shm type tmpfs (rw)
    none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
    /usr/tmpDSK on /tmp type ext3 (rw,noexec,nosuid,loop=/dev/loop0)
    /tmp on /var/tmp type none (rw,noexec,nosuid,bind)
    sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
    
    mount: warning /etc/mtab is not writable (e.g. read-only filesystem).
           It's possible that information reported by mount(8) is not
           up to date. For actual information about system mount points
           check the /proc/mounts file.

    Code:
    root@mercury [~]# cat /etc/fstab
    LABEL=/                 /                       ext3    defaults,usrquota        1 1
    LABEL=/boot             /boot                   ext3    defaults        1 2
    tmpfs                   /dev/shm                tmpfs   defaults        0 0
    devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
    sysfs                   /sys                    sysfs   defaults        0 0
    proc                    /proc                   proc    defaults        0 0
    LABEL=SWAP-sda2         swap                    swap    defaults        0 0
    /usr/tmpDSK             /tmp                    ext3    defaults,noauto        0 0
    /tmp             /var/tmp                    ext3    defaults,bind,noauto        0 0

    Code:
    root@mercury [~]# df -h
    Filesystem            Size  Used Avail Use% Mounted on
    /dev/sda3             899G  498G  355G  59% /
    /dev/sda1              99M   49M   46M  52% /boot
    tmpfs                 988M     0  988M   0% /dev/shm
    /usr/tmpDSK           899G  498G  355G  59% /tmp
    root@mercury [~]#

    Can someone please help point me in the right direction? I am truly lost as to where to start. On the brighter side of things I do have a backup should this be a disaster.

    You'd need to contact your datacenter or NOC again. If the system ran fsck and is still read-only mode afterward, then you'll need to have them check it over. If it isn't salvageable, you'd then need to ask them to setup a new server for you to use your backups.
