Hi, In my testing I make repeated use of the "manual" mkcephfs sequence described in the man page: master# mkdir /tmp/foo master# mkcephfs -c /etc/ceph/ceph.conf --prepare-monmap -d /tmp/foo osdnode# mkcephfs --init-local-daemons osd -d /tmp/foo mdsnode# mkcephfs --init-local-daemons mds -d /tmp/foo master# mkcephfs --prepare-mon -d /tmp/foo monnode# mkcephfs --init-local-daemons mon -d /tmp/foo Using current master branch (commit ca79f45a33f9), the "mkcephfs --init-local-daemons osd" phase breaks like this: 2012-05-24 13:24:06.325905 7fdcd61d4780 -1 filestore(/ram/mnt/ceph/data.osd.0) could not find 23c2fcde/osd_superblock/0 in index: (2) No such file or directory 2012-05-24 13:24:06.326768 7fdcd1ee2700 -1 filestore(/ram/mnt/ceph/data.osd.0) async snap create 'snap_1' transid 0 got (17) File exists os/FileStore.cc: In function 'void FileStore::sync_entry()' thread 7fdcd1ee2700 time 2012-05-24 13:24:06.326792 os/FileStore.cc: 3564: FAILED assert(0 == "async snap ioctl error") ceph version 0.47.1-157-gb003815 (commit:b003815c222add8bdcf645d9ba4ef7e13f34587e) 1: (FileStore::sync_entry()+0x34f0) [0x68e190] 2: (FileStore::SyncThread::entry()+0xd) [0x6a2abd] 3: (Thread::_entry_func(void*)+0x1b9) [0x803499] 4: (()+0x77f1) [0x7fdcd58637f1] 5: (clone()+0x6d) [0x7fdcd4cb4ccd] NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to interpret this. 2012-05-24 13:24:06.327991 7fdcd1ee2700 -1 os/FileStore.cc: In function 'void FileStore::sync_entry()' thread 7fdcd1ee2700 time 2012-05-24 13:24:06.326792 os/FileStore.cc: 3564: FAILED assert(0 == "async snap ioctl error") FWIW, with commit 598dea12411 (filestore: mkfs: only create snap_0 if we created current_op_seq) reverted, I am able to create a new filesystem using the above sequence, and a typical "mkcephfs --init-local-daemons osd" looks like this: 2012-05-24 13:06:25.918663 7fe7ac829780 -1 filestore(/ram/mnt/ceph/data.osd.0) could not find 23c2fcde/osd_superblock/0 in index: (2) No such file or directory 2012-05-24 13:06:26.301738 7fe7ac829780 -1 created object store /ram/mnt/ceph/data.osd.0 journal /dev/mapper/cs32s01p2 for osd.0 fsid f8cc9fa2-a300-45a1-ae6d-e0c0ef418d0f creating private key for osd.0 keyring /mnt/ceph/misc.osd.0/keyring.osd.0 creating /mnt/ceph/misc.osd.0/keyring.osd.0 Thanks -- Jim -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
