2013/12/6 Sebastien Han <sebastien.han@xxxxxxxxxxxx>: > @James: I think that Gandalf’s main idea was to save some costs/space on the servers so having dedicated disks is not an option. (that what I understand from your comment “have the OS somewhere else” but I could be wrong) You are right. I don't have space for one or two disks to be used as OS. I was talking about RAID1 just for OS partition (stored on SSD) and not for the journal. Actually I'm testing OS stored on a USB pen drive with /tmp /var/run /var/lock placed on a tmpfs (ram) and log stored externally via rsyslog. This should avoid USB read/writes (that are slow) as much as possible. It's also very easy to restore to a new pen drive from a failure: dd if=/backup.img of=/dev/sdX bs=4M _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
