    filesystem falls into read only?

    My raid 1 array mount point /storage2 with ext3 filesystem went into read only mode this morning, I can't figure out what caused it but it stop my PVR across the network cold by denying it access.

    This raid 1 is in my fileserver with another array running raid 5.
    also running centos 5.3 and samba 3.2x

    what would cause a filesystem to fall into read only mode during operation?

    A broken disk.

    Look for errors in
    Code:
    dmesg
    and if you have software raids, you can do:
    Code:
    cat /proc/mdstat
    You must always face the curtain with a bow.

    I've restarted the machine that fix the problem, but if it does it again I will run dmesg.

    System does it's raid by the hardware, centos handles the filesystems.

    Not sure what multipath devices are, but it's not a SAN all the drives are local.
