Hi,
I wish to verify things.
Any application is aware only of the file system and not aware of what logical volume is underneath.right?So if one logical volume (from an mirror logical volume) fails,the application still continue to work on this file system.The application open i-node then work with them,and those things are in superblock,means in file system.
The maximum size of the logical volume i can create is limited by the maximum size the file system could support.Right?
The advantages of having vxvm over having only disk partitions are:
- migration online of the logical volume
-take snapshot and then online backup
-convert from linear vxvm to raid and vice versa
-extend,shrink online
All the time is an trade off having vxvm as an intermediate layer over not having this layer but only simple disk partitions.
thanks.
