| Is it possible to make snapshots in a *cluster* LVM environment ?
| Last time I
| read the manual it was not possible.
I highly suspect Nick was talking about _hardware_ snapshotting that is
supported by some SANs, _not_ our clustered snapshot software.
You are right, I don't beleive our enclosure support hw snapshot. It's not
that smart...
But in our case, I don't see what good a snapshot would do.
A little bit more on our client's process. They work on documenting and
publishing documents and images to a so-called "work version" named
doctravail/ (in french ;-). Once they decides a document, image, whatever is
good for production it is copied into the so-called "curent version"
directory named doccourant/.
On theire web sites, there is 3 databases used in rotation, doca, b and c.
At night, data is fetch from their intranet database and pumped into the
next to be used database, and then the data from the doccourant/ is rsync-ed
into the corresponding document directory of the web server.
So I during the night, data from the doctravail/ directory doesn't move. It
won't help if I use a snapshot of that volume to rsync to the destination. I
think...
