Write barriers are not supported in LVM until kernel 2.6.29. There is a
claim of a bug in the implementation, I don't know if it got fixed in
the next release.
So don't depend on your data forced to disk if you're using LVM and
kernel 2.6.29 or earlier.

Subject: [firebird-support] Live backup firebird database using LVM

I need to hot backup large Firebird databases to other physical
locations.
This databases are in LVM partitions.
It's safe to snapshot the filesystem and copy the file database (from
the snapshot of course) to the other location using rsync?
There are any risk to get a corrupted database?

Regards
Christian
