    Question SOS - question on Linux sdf


    Hi,

    I have an urgent issue/question to solve, and would appreciate it if someone could help.

    The system runs RH 5.4. One of the HDD is broken, but we can still see the drive mounted in the OS, and it is still accessible. It can still be read, but all it shows are the data of the HDD just ahead of failure. For example, the HDD of sdf is broken and lost but sdf is still in the system and it shows the content of sde.

    I'm not very familiar with sdf on Linux. Is it an expected behavior? Detailed explanation would be helpful.

    Thanks,
    BJT

    How did you find out, that the disc is broken?

    Other than that, if a disk problem is detected, the affected partition is mounted readonly.
    That may explain, what you experience.

    Backup is in place and functional, I hope.
    If not, now would be a good time

    This issue was reported by an end user. Not very sure how they detected the disk problem at this time.

    Did you mean if disk problem is detected and the affected partition is mounted readonly, then what I mentioned in my original post is an expected behavior?

    Not sure how Linux sdf mapping is supposed to work and behavior. Could someone please explain?

    Thanks,
    BJT

    sdf is the 6th disc of that system
    it starts with sda, then sdb, sdc, etc.

    Yes, it is expected behaviour to deny write access to faulty discs.
    This is to prevent further damage and filesystem inconsistency, but still keep the possibilty to get the data.


    Sounds like you need to verify this "broken disc" information.
    I assume, there is someone to maintain that server?
