Hello,<br>
<br>
I have an XFS file system that's getting 'No space left on device'
errors. xfs_fsr also complains of 'No space left'. The XFS Info
is:<br>
<br>

xfs_db freesp shows that AG 0 seems to be full. I've included the
freesp for the first few AGs, but the rest seem pretty consistent
with AGs 1 - 4 that I've included below. <br>

Is there any way to figure out which files/directories are clogging
up AG 0? Any other ways to abate this issue? Any way to assure
proportional usage of AGs?<br>
<br>
Thanks.<br>
