My OS is redhat7.1, the version of Linux kernel is “Linux version 3.10.0-229.el7.x86_64”
Sometime xfs give a message like this
Aug 11 15:51:05 localhost kernel: XFS (dm-4): metadata I/O error: block 0x7d9a010 ("xfs_trans_read_buf_map") error 117 numblks 16 Aug 11 15:51:05 localhost kernel: XFS (dm-4): xfs_imap_to_bp: xfs_trans_read_buf() returned error 117.

So is this a bug of xfs? or is the device’s error(the device actually did not save the data, but give xfs success message)?
