We haven't installed VM yet. The Linux test LPAR has 512MB of memory, of which over 480MB is shown as the buffer, crippling the system.
Would you know how FSCK works ? Is it supposed to allocate and free the buffer space for the file system ? Would you recommend that we run FSCK regularly ? Is there a way to force the system to free the buffer ?

Almost all available memory had been taken up for the buffer (480 MB of 512MB), and the OSA failed on IPL due to a memory shortage. Would someone know how the buffers are allocated and freed ? Thanks Kay
