Using ceph version 0.3 and the ceph kernel that comes with ubuntu 11.04. I've setup 5 osds and one one mon and mds on one machine. When I first started, without writing any data to the ceph fs my mds would keep crashing. I fixed that problem by deleting the mod data directory and the ceph data directories and restarting ceph. I then started copying test data from a 2tb external drive to my ceph fs. I left my computer and came back and could not login to my machine. I saw that the external drive light was blinking so something was going on. I did a hard power off thinking I would just delete the last file that was copied over and start over.
As expected, I could not start up ceph again. I had to delete all the data directories again to get ceph up again. Is there any way to flush whatever to get ceph back to some sort of stage where you can enter back into the fs without having to purge everything a start over? -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
