    SMB disk IO halts while other disks spin up


    ptr727
    • Minor

    I noticed that existing SMB network IO will halt while a new disk spins up, even if that disk has nothing to do with servicing existing IO requests.

     

    E.g. start a ffmpeg encode session for source and destination media on the SMB network share, wait for other disks to spin down, ffmpeg chugs along, open file explorer and browse around the SMB filesystem, every time you hit a share with disks spun down there will be a delay while the disks will spin up, while the disks are spinning up ffmpeg transcoding halts until the disk is spun up.

     

    Expected behavior is that existing IO is not halted while unrelated disks are spun up that have nothing to do with servicing that IO.

    This is usually controller related, i.e., some controllers do this, some don't.

    Seems highly unlikely that this is a LSI controller issue.

    My guess is the user share fuse code locks all IO while waiting for a disk mount to spin up.
