I don't think anyone will hit this unless they are using an updated<br>
xfsprogs or have explicitly enabled crc. The shipped xfsprogs is 3.2.2<br>
which does not enable crc checking on file systems by default. E.g.:<br>
<br>
# xfs_info /<br>
meta-data=/dev/sda7 isize=256 agcount=4, agsize=4874176 blks<br>
= sectsz=512 attr=2, projid32bit=1<br>
= crc=0 finobt=0<br>
data = bsize=4096 blocks=19496704, imaxpct=25<br>
= sunit=0 swidth=0 blks<br>
naming =version 2 bsize=4096 ascii-ci=0 ftype=0<br>
log =internal bsize=4096 blocks=9519, version=2<br>
= sectsz=512 sunit=0 blks, lazy-count=1<br>
realtime =none extsz=4096 blocks=0, rtextents=0<br>
<br>
Notice the crc=0.<br>
<br>
If someone has enabled crc=1, then yes I imagine they could run into this.<br>
