Hi, i am trying to port a local file system other than ext3,ext4,btrfs to manage the OSD. There are some reasons for us to do it. the mkcephfs stopped at this point: 2013-02-07 11:39:32.009889 7effe43d17a0 -1 filestore(/mnt/osd.0) mkfs failed to create leveldb: IO error: /mnt/osd.0/current/omap/MANIFEST-000001: Invalid argument 2013-02-07 11:39:32.009907 7effe43d17a0 -1 OSD::mkfs: FileStore::mkfs failed with error -1 2013-02-07 11:39:32.009949 7effe43d17a0 -1 ** ERROR: error creating empty object store in /mnt/osd.0: (1) Operation not permitted
Does your ssh user have permission to create dirs in /mnt? (I'll grant you it looks like you're doing root, but, still)
failed: 'ssh root@mon-mds /usr/local/sbin/mkcephfs -d /tmp/mkfs.ceph.2686 --init-daemon osd.0'
You could certainly try this command on the failing system as root, and look with strace to see what system call is actually failing.
look into the code, it failed at os/FileStore.cc --> leveldb::Status status = leveldb::DB::Open(options, omap_dir, &db); Does anyone have any suggestions? Thanks, Sheng
