Today I tried to increase the logical volume on a UTM-1 appliance as described before in this blog.
I got the errorresize2fs: Operation not permitted While trying to add group #128
when issuing the resize2fs command.
The solution to this problem: the journal was to small and had to be re-created:
[Expert@firewall]# dumpe2fs /dev/vg_splat/lv_log | grep Journal\ size
Journal size: 32M
[Expert@firewall]# tune2fs -O ^has_journal /dev/vg_splat/lv_log
[Expert@firewall]# tune2fs -j /dev/vg_splat/log
Creating journal inode:
done
[Expert@firewall]# dumpe2fs /dev/vg_splat/lv_log | grep Journal\ size
Journal size: 128M
After that do a filesystem check and issue the resize2fs command, which will succeed.
