Hello!
I'm wondering about MySQL LVM2 preformance, but cant found any
comparisions. I know that there is some speed decrease with LVM,
something about 30%. But how this decrease impacts overal MySQL performance?
Now we are backuping replication slave server with mysqldump w full
table locks, this takes some time. I think better solution is to use LVM
snapshots, but this performance decrease really scares me. Has anyone
some advices on this?
