Hi,
We would like to do some operations on a ext2 disk while it is mounted
read-only.
The problem is that our operations have no effects because everithing is
cached.
Is it possible to shrink all the caches, especially the superblock
caches and to reload the changes?
We used prune_dcache (kernel 2.2.14) and dev_fsync . It has some effect
but none on the superblock and
the root of the disk.
Thanks by advance
-- Fred and Tom
