How to extend a filesystem on serviceguard cluster?

[Fernando Boza]

I have a cluster serviceguard with 2 nodes HP-UX 11.11.
How I extend a filesystem on the cluster?
I need down the pakage? or only I need umount the filesystem?

[Emil Velez]

lvextend
fsadm -F vxfs -b XXXXM /


assuming you have onlinejfs and space in the volume group

Hi

Well, the question is, is this file system shared by both nodes? Or is it local to each node like /opt in vg00?

For a shared file system between both nodes, once you extend the logical volume and then the file system on one node, then you're done. When the cluster package fails over the change will still be there.

See above response and lvextend, fsadm -b commands to complete.

For a local file system like /opt, then you have to perform the procedure on both.

if you have Online Jfs - Installed, You can extend your file system on the cluster by Online


lvextend -L /dev/vgxx/lvolxx

fsadm -f vxfs -b /file_system_name

or only I need umount the filesystem?<<<


if you d'not have Online - Jfs, you need to halt the package-

lvextend -L /dev/vgxx/lvolxx
extendfs -F vxfs /dev/vgxx/rlvolxx

to check Online Jfs Installed.

swlist -l product |grep -i jfs

Hi Fernando,

You can refer below link:

Start from step 6.

can you provide the FS details which u need to extend . Is it part of Vg00 ? Is it part of pkg ?
Is there any free PE on that Vg ?
Online jfs is there ?

Extending is File system in serviceguard env.

if spcae is avaible then ;

Lvextend -L Lvname
fsadm -b M mountpoint

if space is not there and addition of disk then

pvcreate
vgextend with new disk.
lvextend
fsadm
export mapfile

and importing the mapfile on alternate node.

Hope you aware of commands.
