How to increase filesystem when running HAGEO in AIX

[lblauen]

How do you increase the filesystems space when running hageo. I know how to do it in AIX and with hacmp running but hageo with its gmd's i'm not sure how to do it. Any help I would invite. I think you must have to shutdown hageo then mount the real filesystem not the gmd then increase it then what....

hi ,

Firstly what version of hageo do you have installed ?
If the latest ( thats if there is one) is there an option to increase the filesystems using DARE like HACMP if not
then you will need downtime to increase the filesystems

Have a look at the following procedure , its been a long time since we have done this but hopefully it'll give you some idea , and if you can try it out first i.e. create a test LV and GMD may be worth while.

Manually
1. stop application using the filesystem
2. you have to create a dummy JFSLOG
3. edit /etc/filesystems and change dev= and log= to point to dummy JFSLOG
4. Change the log attribute to use the dummy log
chfs -a log=dummy jfslog /filesystem point
5. Increase the size of the filesystem
6. increase the size of the logical volume on the remote
server
7. Re-instate the original /etc/filesystems
8. THen sync the GMDS but first you have to make them dirty
i.e, gmddirty -l ( GMD)
then sync the GMDS

Hope this gives you some insight.

I'm running 2.4.0.4 hageo
AIX 5.1 fixpack 5
hacmp 4.5.0.10

I will look around and see if DARE is installed. If not I guess I have to do it manualy. I'll see what happens. Thanks

It took me a while but I found out in the High Availabilty Geographic Cluster for AIX Guide the following command:

geo_chfs -a size=20643840 /db2dump

It increased the filesystem on both primary and secondary system and then synced it up. I didn't have to shut hageo or hacmp off. I works on the fly.
