2.4.25--pre4 VFS lvm_snapshots
Quoted 2 lines · Christoph Hellwig
The patch still doesn't get better by that. And even if it was this would clearly be a feature for 2.6, not 2.4.
Without this patch there is no warranty that a LVM_snapshot is updated like the FS that is trying to replicate. DANGER !!!
I only see one solution:
to stop FS IO, and then # sync; sync; sync; lvcreate -s ...
Maybe it's needed to write, in the code or a doc, some warning about this or to put a pointer to this patch :-?
