parallel extendfs?

Are there any issues with running extendfs many times concurrently?

Hi

There is no problem providing you dont try to use the same fs simultaneously.

try it out on a development or test box.

Hi

The only problem with extendfs is that the filesystem must be unmounted. IF you have OnLine JFS you can do the same thing whilst the filesystem is still mounted with "fsadm"

When doing maintenance on the LVM, you can only do one action at a time. The system puts a lock somewhere and when you try to do a second action, it waits for the lock to be released.

Hi Daniel

Ther copuld be no issues , but this a admin command typically to be run by root or one at a time and anyone would prefer not to run this concurrently as it is not rquired to be run . Also if you dont have a online JFS then you need to unmount it befroer you run so it can be run by the peron who umounts it , alos if you have online JFS then also it would be always better for one person to run it .

I've got a lot of file systems, and running two or three at a time worked just fine - and saved a bit of time.

Thanks for the replies.
