FAT got unmounted every time, but XFS does not, /dev/sda2 on /dtv/usb/sda2 type xfs (rw,relatime,nouuid,attr2,noquota) /dev/sdb2 on /dtv/usb/sdb2 type xfs (rw,relatime,nouuid,attr2,noquota) If I do sync on Shell I got below error. xfs_force_shutdown(sda2,0x1) called from line 1004 of file fs/xfs/linux-2.6/xfs_ buf.c.
