[Ocfs-users] Resize ocfs....?

[Marcos Matsunaga]

Resize ocfs....?Well,

When I talked about dynamically expanding the partition, and that partition is in a clustered drive, the utility has to be cluster aware.

In this case, if you use parted or fdisk (they are not cluster aware), you would have to unload/load  the HBA driver (easiest way) on all other nodes in order to see the changes that nodeA made. 

As rule for any operation that may involve loss of data, don't forget to get a good backup before performing any changes.

  ok, will look into. sort of off topic....

  as the parition is located on a clustered drive.
  if I dynamically expand the partition on NodeA.  do I need to change any files on my other nodes?
  or should they dynamically determine the partition size avail?

  Have you resized your physical partition? Does it have the 100Gb for the filesystem? 

  Based on your description, your physical partition has only 59Gb. The filesystem size is limited by the partition size. If you have some utility that allows you to dynamic resize your physical partition, then good for you. If not, you have to take a backup, re-create the partition with 100Gb, reformat and restore the backup. In this case, better creating additional datafiles for the tablespace(s) in some other ocfs filesystem that has available space.

    I've tried several times to resize one of my ocfs volumes[see emcpowere1 below] 
    I'm on the latest [prod] version of ocfs/ocfs-tools as of 3pm EST on 18JUL04. 
    Per instructions... 
    Take down db, unmount all ocfs drives, use ' tuneocfs -F -S 100G /dev/emcpowere1 ' 

    Supposedly this should work, but I get get.... 
    The size specified, 100G, is larger than the device size, 59G. 
    Aborting. 



    What am I doing wrong?
