We recently applied TL on few of our test servers. All of them were running fine except on one server. TL upgrade was successful on all these servers.
i see below errors on a server.

I understand that, it is because we do not have enough space on jfs2log lv.
because the (rootvg) pp size is only 8 MB on this server.
is there any procedure to increase the jfs2log size on the fly (dynamically). with out bringing the server ?
The above link says, we need to boot the server into service mode and run logform etc .
The problem is: to change the log volume you need to unmount all the file systems using the log LV you want to change. As you said this is your rootvg you would have to unmount all the filesystems vital to the OS to do so. This is why you need to boot into service mode.
On the other hand, i suggest you do a fresh install anyway. Even for a rootvg a PP size of 8MB is way too small todays. I suggest you take a backup, then reinstall the server using a reasonable PP size, like 32MB, 64MB or even bigger, depending on the size of your rootvg disk(s).
As Bakunin suggested you don't want to play with your rootvg, generally speaking logfile is created automatically (it gets created, when 1st lv is defined in the VG), and you are not creating it manually.
What version of OS are you running?
What other file systems do you have apart from native rootvg's filesystems?
You might also want to take a look at the TL level you jumped to for any known bugs or additional APAR's.
The error type says 'INFO'. So you may not need to do anything at this moment. Wait and watch if more errors are being logged before you make any changes
Can someone please help me understand what it is I am doing incorrectly?

Hi Guys,
I wonder if after enabling CIO/DIO at the filesystem level and assuming that CIO/DIO will bypass the JFS2 read ahead available when not using CIO/DIO my questionis what parameters I can play with to tune/improve the CIO in order to obtain similar performance for sequential reads (... (7 Replies)
We are using AIX 5.2 using jfs2 almost all excpt one mount.

Please advise if this is possible
Thanks (2 Replies)
