Problem when resize ext3 file system online

Latest response

Dear All,

 

Is there anyone who do research into resize ext3 file system online (mountedt with rw mode). I have tested some cases in which I used dd command to create some files ( > 1G each file) and resize file system at the same time. After that, I usually encountered some problems, such as "Free blocks count wrong" or "Free inodes count wrong", like bellow. If I choose Yes (y) to fix the problems, there are many files were lost. Dit you do some test case like mime?

 

I feel that ext3/ext4 file system are more difficult to manage thatn jfs2 on AIX, especially when resize them. I live environment, some time I must resize online, and maybe in future I can use RHEL for core banking. So Down time seems to be unaccaptable. Did you compare these file system, Pros and Cons of these?

 

Thanks for your ideas.
