disk size on /vol_HDB/shared

Hi all,

When I check disk usage, I observe that 94% on the /vol_HDB/shared volume.

But this time it is coming from following directories

22G on /vol_HDB/shared/HDB/global/hdb/log/mnt00001/

14G on /vol_HDB/shared/HDB/exe/

When I have a look at /vol_HDB/shared/HDB/global/hdb/log/mnt00001/

I see that there are 4 directories (hdb00001, hdb00002, hdb00003, hdb00004) and in each directory there are some dat files also says DO_NOT_TOUCH_FILES_IN_THIS_DIRECTORY as you can see below in the pic.

So I didn't delete these dat files. Should I delete them to make more free space or what do you suggest to me? Or is it normal to have 94% on /vol_HDB/shared ?

Thanks,

Inanc
