Hi, I was wondering if the Logical Volume Manager (LVM) on for example SuSE 7.3 is any good in a proffesional "24 x 7 x Forever" "many GB/TB's SAN" production enviroment. In my/our company's case being able to logically expand hardware raid sets and partitions in a real production enviroment is important. We plan to use linux because Linux itself is stable and robust enough and a good alternative to say SUN Solaris. But downtime due to a problem with the Linux LVM is not an option. Normally, we would add an array within the SAN and then create a new (very big) filesystem on it and mount it. But when we could expand a partition on the fly that would be better. And can the LVM be used with RedHat 7.2 as well (i can't find it on the distro) ? How does EXT3 (we need journaling) behave on very large filesystems (many GB/TB's) ? I like EXT3 because loss of the journal do not pose big problems because the partition can be mounted EXT2 and run until a time-window arrives to repair the journal and mount it back again with EXT3. It's all about MASSIVE fileserving. In short: are LVM and EXT3 mature/stable enough ?
