Hello again. I'm having a problem with LVM, and I'm really, really hoping you won't tell me it's because of: # CONFIG_NOHIGHMEM is not set CONFIG_HIGHMEM4G=y # CONFIG_HIGHMEM64G is not set CONFIG_HIGHMEM=y CONFIG_HIGHIO=y (linux kernel 2.4.21, lvm 1.0.7 stuff installed) I've got 8 boxes with 4 gig of memory, and 6 200 gig drives in a raid 0 setup, and I need to use LVM+Snapshots. I can setup and create a 1.09T logical volume, but when I go to create a snaphot, I get: lvcreate -- INFO: using default snapshot chunk size of 64 KB for "/dev/vg0/test" lvcreate -- ERROR "Cannot allocate memory" creating VGDA for "/dev/vg0/test" in kernel Now, in reading past posts there is some talk of how having "high memory" turned on will cause problems with snapshots. The problem is that on these machines I *need* 4 gig of memory, and I *need* snapshots.
