I'm having an issue with glusterfs exceeding its cache-size value. Right now I have it set to 4000MB and I've seen it climb as high as 4800MB. If I set it to 5000, I've seen it go as high as 6000MB. This is a problem because it causes me to set the value very low so that my apps don't get pushed into swap. Is there any way to fix this? To get it to stick to the limit I set and not exceed?
It's possible you are running into the same memory leak that I'm seeing, and I'm not using io-cache or any other performance translators at all. With rootfs on Gluster, doing a kernel compile (kernel source tree being on NFS, so this won't be contributing to the bloat, hopefully) makes the glusterfsd bloat by about 80MB per pass, and never frees it.
