I mounted my xfs_disk. Then I run : xfs_db -f -c "sb 0" -c "p" ./loop | egrep 'agcount|inopblog|agblklog' It said: xfs_db: unexpected XFS SB magic number 0x2e524d46 Floating point exception I don't know what the problem is. But if I umount my xfs_disk, Then I run xfs_db {my_xfs_device} xfs_db>sb xfs_db>p It's OK.But I can not see things about ./myfile now, since my xfs_disk is umounted. 2) I have to umount my xfs_disk before I use xfs_db, correct? 3) If I want to read the inode content of a file, say, myfile, I should "ls -li myfile" to get the inode number of myfile Then "xfs_db> inode " to read the content of inode Is what I said correct?
