Hi, I have a Ceph cluster, used through radosgw. In that cluster, I write files each seconds: input files are known, predictible and stable, there is always the same number of new fiexd-size files, each second.
Theses files are kept a few days, then remove after a fixed duration. And thus, I want to remove the same stable number of files each second (I want to remove them faster than store them, or my cluster will grow to death) On a daily-basis, I look at my files, remove the useless ones, and force the gc process. The first part of the process is quite fast (couple of minutes). The last part (gc process) is, however, a bit slow. Is there a way to speed up the garbage collection ? Is the GC dedicated to a radosgw (meaning : if I remove & gc process from multiple radosgw, will the process be faster ?) >From my experiment, multithreading the gc process using some stuff like parallel is not efficient (I guess gc processes are locking each others or something): is that true ? Thanks for advises! _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
