If you have OnlineJFS installed on your system then you can extend the FS online.

Re: extending the FS on clusters in online..
> if we need to extend or reduce the file system on the cluster servers, can we do it online or offline.
- Yes you can do it online, OnlineJFS will take care of it just like extending normal filesystem. Make sure you have free PE.
- Unless you are adding disk, it is online and straight forward, for adding disk in case of shortage of space you have to , export and take map file and import the vg in the failover node, so that correct disk information will be present in both the node.
- If Free space is available on the vg , you can extend it online.

Re: extending the FS on clusters in online..
- To extend the FS:
1.# check space: # vgdisplay vg_name | grep -e "Free PE" -e "PE Size"
2. # lvextend -L
3. # fsadm -b
4. # bdf /mount_point
Cheers,
Raj.

Re: extending the FS on clusters in online..
The best information you can get on MC/SG is to read the documentation. Then when you run into an issue, post the problem here and folks will try to help you.
The Forums is not intended to replace the value of the book that was written to answer all of the questions being posted here. Honestly, you are not learning service guard properly this way. Read the book, schedule some training classes if possible where you will have plenty of labs to play with it.
Please....download and read the documentation.
