So let me make sure I understand what happened. Ceph made sure no file existed with this name, and created with the first write log entry: 2011-07-31 23:06:49.173941 7f23c048c700 filestore(/osd.0) write temp/10000000483.000005d6/head 0~1048576 = 1048576 It then linked it into this directory: 2011-07-31 23:06:50.114287 7f23c048c700 filestore(/osd.0) collection_add 0.69_head/10000000483.000005d6/head temp/10000000483.000005d6/head = 0 … and removed it from the temp directory: 2011-07-31 23:06:50.114316 7f23c048c700 filestore(/osd.0) collection_remove temp/10000000483.000005d6/head = 0 and then created three inodes that totaled approximately 240 bytes in length or so (including the name and headers) 2011-07-31 23:06:50.114384 7f23c048c700 filestore(/osd.0) setattrs 0.69_head/10000000483.000005d6/head '_' len 161 = 161 2011-07-31 23:06:50.114406 7f23c048c700 filestore(/osd.0) setattrs 0.69_head/10000000483.000005d6/head 'snapset' len 26 = 26 2011-07-31 23:06:50.114413 7f23c048c700 filestore(/osd.0) setattrs 0.69_head/10000000483.000005d6/head = 26 … and then presumably the file was closed and that would have been the end of this file being touched by ceph, correct?
