We're a Solaris shop looking at RedHat Enterprise Linux and one of the things we're wondering is if we should keep Veritas Volume Manager + FileSystem or go with LVM+ext3 or RedHat's preferred cluster filesystem solution, GFS.
One of the things we like about Veritas is that it can use Veritas Volume Replicator to have a remote copy of important filesystems. This functionality seems to be missing from RedHat, DRBD doesn't seem to be packaged in RHEL...
So my questions are:
- Does anybody use VxFS/VxVM/VVR on Linux? Thoughts, experiences? Comparison with LVM+ext3?
- Anybody using GFS? Thoughts, experiences?
- Do you do remote replication for disaster recovery, and if so, how? Is there a standard RedHat way?
