Online jfs filesystem resizing when it has mount points active below it...

[compiler]

I've been testing fsadm to do "online vfxs resizing" and it's working nicely:

(example: fsadm -F vxfs -b 102400M /myfs)

My question is ... Is it possible and safe to do online JFS resizing on a filesystem that has other partitions mounted into it?

Example. We have:

/myfs /dev/vg01/lvol1
/myfs/logs /dev/vg01/lvol2
/myfs/data /dev/vg01/lvol3


Would be safe to extend /myfs without umounting /myfs/logs and /myfs/data ?

Thanks.

Hi:

You should not have any problem. Each is a separate filesystem to VxFS (JFS).

Thanks a lot :)

The answer is "Yes. It's supposed to be safe and possible".
