I booted one up and sure enough the LVM program has the option => Expand !
Yes, that is where it is done. ECS has the same menu item.
Don't Expand.
In this case it's impossible recover data from broken JFS volume.
Two comments on that: 1) It is almost impossible to recover data from a normal volume, broken or not. That is what backups are for. 2) It has been a number of years since I saw a broken volume.
I will agree that merging them might cause new problems, but that is one of the reasons why I want to give it a try. There is also one line in CONFIG.SYS, that doesn't need to be there, if it is not going to work.
But I fear I don't fully understand what you're want to do as the answer is too simple.
I am in a position where I want to merge a couple of volumes, and the LVM Expand option would seem to be an obvious answer to how to do it. I have done the method where both volumes are deleted, then create a single volume in the freed area. In fact I have two machines, with pretty much the same requirement (all on one disk), with a third that has the two volumes on separate physical disks. The third one is an old test machine, so I may try that first. I should have enough room to put all of the data on the one volume, then expand it into the freed area where the other volume is now (after freeing it). I don't think I can just paste the two volumes, and their contents, together, but I may see if there is a way to do that. In the third case, it is not possible to simply delete the two volumes, and create one in the freed area.
Since it seems that nobody has actually done it, I will need to do a bit more research, and see what happens. Somebody may find the information useful.
Thanks for the comments...
