• dcache error on cmspn02.ihep.ac.cn, 4/8 disk, sda1 sdb1 sdc1 sde1 failure.
    1. /etc/init.d/dcache stop => umount /storage/disk=> do xfs_check /dev/sd1 => xfs_repair => but after a while it will happen again.
    2. suspect that the network device have problem => change a fibre-optical fbi => switch two fibre-optical, get the results that another 4/8 disk error.
    3. waiting for change a disk storage array controller.
    4. Due to we can only get little time after a xfs repair, it's not available to migrate all the datas on cmspn02 to another dcache pool.
    5. We think that's the main reason for transfer failure to IN2P3.
