Thanks Kyle,
--I'll look into and try out udev and upstart.
-- yes on set noout, definitely a good idea, until for sure that osd is gone
for good.
If osd disk is totally gone,
Then down-n'-out.
Remove from crushmap/Update crushmap.
Verify crushmap
Then used ceph-deploy to add a replacement
This Just happened to me yesterday:
A 90 32GB VM ROOT IMAGES stored in one 3TB RBD/XFS volume.
Mounting this volume gave an error, structure needs cleaning and won't mount.
Ran xfs_check.
Ran xfs_repair.
Mouted rbd volume, no error.
Booted all 90 VM ROOT IMAGES.
Have not used EXT4 on OSD's or
kernel-3.4.59-8.el6.centos.alt.x86_64 is what you want, it has ceph rbd.ko
driver.
