Hi,

I updated kernel from 2.6.27 to 2.6.35 and noticed that free size on my 
xfs volume changed. Before update there was 7MB free space, now there is 
none.

After some investigation I found that default size for reserved block 
pool changed [1].
On this volume I have one very big file which is exported as iSCSI disk 
via SCST and one small configuration file. The big file size will never 
change. Small file size can change only by some KB.

With this assumptions, can I revert this change and set reserved blocks 
pool size to 1024 blocks?

Reagards,
