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 .
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?
