Hello. I'm new to ceph, so suggestions and guidance and advice as to what works and what fails is most appreciated. Hardware (3) FX8350, 32G ram, (2)-2T drives each, running gentoo. Each system has btrfs-raid one set up like so: Disklabel type: gpt Device Start End Size Type /dev/sda1 2048 8191 3M BIOS boot partition /dev/sda2 8192 1024000 496M Linux filesystem /dev/sda3 1026048 3907029134 1.8T Linux filesystem Found valid GPT with protective MBR; using GPT. # blkid /dev/loop0: TYPE="squashfs" /dev/sda1: UUID="85cd9d86-4f4d-4113-b14e-cf5339373e20" TYPE="ext4" PARTLABEL="grub2biosboot" PARTUUID="f88a8259-a4e4-4db8-86df-e709d135fe47" /dev/sda2: LABEL="BOOT" UUID="d67a8d19-64bc-4ee1-bebf-48c935b039fa" UUID_SUB="3eb62dd8-3f07-440f-8606-0c6d99362f6e" TYPE="btrfs" PARTLABEL="boot" PARTUUID="8a6f7b5f-28a8-4f87-938f-386a93ebe07f" /dev/sda3: LABEL="BTROOT" UUID="b7753366-a9a9-4074-8e0e-3beea50fee56" UUID_SUB="e546ce31-098f-4897-bffd-6c5628f6b62e" TYPE="btrfs" PARTLABEL="root" PARTUUID="6a8fa54b-3d58-4ac5-8784-6d540f2e65fc" /dev/sdb2: LABEL="BOOT" UUID="d67a8d19-64bc-4ee1-bebf-48c935b039fa" UUID_SUB="02034edf-c537-4fc6-9375-1599e8af2737" TYPE="btrfs" PARTLABEL="boot" PARTUUID="b7b88ea7-b59a-4a4d-b857-4f55a1be3830" /dev/sdb3: LABEL="BTROOT" UUID="b7753366-a9a9-4074-8e0e-3beea50fee56" UUID_SUB="8a76be85-6106-47ea-90ae-756fb8c37bf1" TYPE="btrfs" PARTLABEL="root" PARTUUID="3c2c6f88-a1da-40de-83be-21af71a5ce26" /dev/sr0: UUID="2014-08-28-06-08-20-22" LABEL="Gentoo Linux amd64 20140828" TYPE="iso9660" PTUUID="1047d058" PTTYPE="dos" /dev/sdb1: PARTLABEL="grub2biosboot" PARTUUID="3c7a0935-57d4-4bff-a492-aaa261e62212" Goals: To set up a simple (3) nodes with cephfs for experimentation with cluster codes; Mesos and Spark being first in line. Right now I'm working to get v 0.87 (Giant) into gentoo as an overlay. Comments on witch version of Ceph to use, including the daily (9999) version are welcome. After reading, it seem that COW operations are still troublesome with ceph? So using a raid1 on each node with btrfs will allow me to turn off COW if/when those sorts of issues arise. What I need help with right now is setting up the UUID based /etc/fstab and suggestions on exactly how to configure ceph(fs). My desire is to keep the btrfs-gentoo installs stable but to be able to use ansible or other (ceph based tools) to reconfigure ceph or recover from ceph failures.
