Impact of large logical volumes

[Ana Lúcia Moreira]

Hi,

I have a volume group with a 73G hard disk.

What impact if I create only 1 logical volume with all this space, instead of dividing it into 3 or more logical volumes?

Thanks,

Joice.

Hi,

Depending on the type of disk and exactly
what you put on it, you shouldn't have
any problem. The only difference would
be from a manageability viewpoint.
These days many SA's are creating
bigger and bigger logical volumes and
filesystems.

Have a look at this chart for current sizings.

hi,

I would always prefer to have a bunch of reasonable spaced filesystems (size around 25 gb), unless the user applications really demands a huge filesystem (which is an exception).

That way, if there is a filesystem corruption, you isolate the problem to only one filesystem and not a huge 73 gb piece.

You will also have the flexibility of unmounting, mounting the filesystems without and dependency.
