The operation that causes major leakage is making the initrd for Open Shared Root (much more involved than normal mkinitrd, as it makes repeated calls to the rpm database, which, in this instance, is in SQLite format because BDB flatly refuses to work on GlusterFS). Leakage is approximately 1MB every 5 seconds during the operation, and GlusterFS uses 100% of CPU while the operation is occurring (which is in itself a tad worrying even if it is running on a 1.6GHz Atom 330, which is not exactly an underpowered machine). rootfs is AFR, but the machine is operating standalone (no peers connected).
I have just put it back as it was (mounted with -o direct-io-mode=off,log-level=NONE,log-file=/dev/nulland sure enough the leak disappeared. The CPU usage is also down to a much more reasonable 25-30%.
Should I bother with a bugzilla report, or is this already a known issue in 2.0.2?
