Also,

Not sure if this helps but when this happened, any file that was open()
for read/write seem to have also been corrupted..

$ /usr/sbin/xfs_bmap -v myconfig.txt.orig
myconfig.txt.orig:
  EXT: FILE-OFFSET      BLOCK-RANGE        AG AG-OFFSET        TOTAL
    0: [0..7]:          64601112..64601119 14 (52040..52047)       8
$ /usr/sbin/xfs_bmap -v myconfig.txt
myconfig.txt:

$ strings -a myconfig.txt.orig

$ od -c myconfig.txt.orig

Seems like it was NULL'd out?
