My problem is I can;t find a "5 minute quickstart guide" for RHEL 6. and I didn't get a "running ceph cluster" by trying to follow the existing (ubuntu) guide and adjust for centos 6.3. So I'm stuck at a point way before those guides become relevant: once I had one OSD/MDS/MON box up, I got "HEALTH_WARN 384 pgs degraded; 384 pgs stuck unclean; recovery 21/42 degraded (50.000%)" (384 appears be the number of placement groups created by default). What does that mean? That I only have one OSD? Or is it genuinely unhealt= hy? --=20 Dimitri Maziuk Programmer/sysadmin BioMagResBank, UW-Madison -- http://www.bmrb.wisc.edu --------------enig28301531FBA5F7AEC010D049 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iD8DBQFRAHwMxzG8ttqkbbgRAkPTAKCz4sBaf0CSUC1I7Tx6yRl1dGd80ACeMTbX QXyjsZ4/ww/sKRrw6PjPUpc= =1uco -----END PGP SIGNATURE----- --------------enig28301531FBA5F7AEC010D049--
