Hi all,
As of my knowledge, bluestore has label which can be shown by "ceph-bluestore-tool show-label --dev /dev/ol/osd0"
{
"/dev/ol/osd0": {
"osd_uuid": "e8a4422f-4f01-4d7a-9b3c-65ff25101d8b",
"size": 5368709120,
"btime": "2022-12-22T13:29:52.351106+0800",
"description": "main",
"bfm_blocks": "1310720",
"bfm_blocks_per_key": "128",
"bfm_bytes_per_block": "4096",
"bfm_size": "5368709120",
"bluefs": "1",
"ceph_fsid": "881cc772-0b19-4ce9-9a69-2637fb9bd91e",
"kv_backend": "rocksdb",
"magic": "ceph osd volume v026",
"mkfs_done": "yes",
"osd_key": "AQBO66Nj1kGpMxAAW8vgakGmaTc+yFWYX0a03g==",
"ready": "ready",
"require_osd_release": "16",
"whoami": "0"
}
}
After I reboot my VM, and try to run this command again, I will get error:
unable to read label for /dev/ol/osd0: (2) No such file or directory
The partition is there, and can even be recognize by "ceph-volume lvm list", but due to the label is lost, I can't activate it.
Has anyone encountered such issue before?
Any input is appreciated.
Thanks a lot.
Regards,
Isaiah Tang
