Re: How to Know the Online file system in LINUX

"Online filesystem" is not a standard term - perhaps you mean the capability for online extension, like OnlineJFS product on HP-UX?

In Linux, online filesystem extension is not a separate product, but a standard feature. The "resize2fs" tool is always included in a RHEL5 installation.

Resize2fs works on ext2 and ext3 filesystems (and also ext4 if you have the appropriate RHEL 5.x updates installed). It will automatically detect if a filesystem is mounted, and will perform an online extension operation in that case.

If you mean VxFS (aka the OE'd from Veritas OJFS product on HP-UX) - then :

$ rpm -qa|grep VRTSvxfs
VRTSvxfs-platform-5.0.30.00-MP3_RHEL5

or

$ man mount_vxfs

or check /opt if there are VRTS bits there.
