The solution appears to be to apply the patches in the other order. To create a kernel capable of making a snapshot of an active ext3 or reiserfs volume, the drill appears to be to apply the VFS-lock patch for the appropriate kernel version to the un-patched kernel tree, and only THEN to apply the generated LVM patch. This makes me wonder if it would be possible to add this to the configure script, so that I could say configure --with-VFS-lock I envisage makeing --with-ext3 and --with-reiserfs aliases for the above. Just an idea. > -----Original Message----- > From: C R Ritson > Sent: 09 May 2003 16:51 > To: 'linux-lvm@sistina.com' > Subject: stock kernel 2.4.20 + LVM 1.0.7 + ext3fs => snapshot problem? > > ... cannot make a snapshot of a mounted > ext3 filesystem.
