Extending filesystem.

[rveri]

Hi, what is the procedure to extend a striped logical volume, the VG contains 8 disk. The Striping is 2 . And online JFS is installed. Free PE available to 3 disk and 0 PE to 5 disk.

Thanks in advance.

Shalom,

There is no need to offer 10 points to every reply. This may result in clutter in your thread making the solutions harder to find.

That being said, this is a very complex, probably needlessly complex Logical volume.

If possible, I would.

1) Back up all the data, and rebuild the entire thing. Extending under these circumstances could create hot spots and major performance problems.

2) If option 1 is no good, you can lvextend, maybe sam would be helpful. After lvextend fsadm extends th filesystem not. Note that for true striping, you will need to lvexent in small chunks, rotatinig them across the three disks. I'd use a script to accomplish this. Again, performance problems are VERY likely under this scenario. The fsadm hot extension can wait until after all the scripted lvextend work is complete.

You asked.

I'd go for option 1 if at all possible.
