Thanks. I was forced to change some journal, using some partition (MBR); i've stopped osd, flushed old journal, changed symplink and then do a 'journal format': root@deadpool:/var/lib/ceph/osd/ceph-6# ls -la totale 64 drwxr-xr-x 3 root root 199 feb 6 17:45 . drwxr-xr-x 6 root root 4096 dic 14 2016 .. -rw-r--r-- 1 root root 751 dic 14 2016 activate.monmap -rw-r--r-- 1 root root 3 dic 14 2016 active -rw-r--r-- 1 root root 37 dic 14 2016 ceph_fsid drwxr-xr-x 378 root root 20480 feb 6 17:12 current -rw-r--r-- 1 root root 37 dic 14 2016 fsid lrwxrwxrwx 1 root root 9 feb 6 17:45 journal -> /dev/sda5 -rw------- 1 root root 56 dic 14 2016 keyring -rw-r--r-- 1 root root 21 dic 14 2016 magic -rw-r--r-- 1 root root 6 dic 14 2016 ready -rw-r--r-- 1 root root 4 dic 14 2016 store_version -rw-r--r-- 1 root root 53 dic 14 2016 superblock -rw-r--r-- 1 root root 0 feb 6 17:10 sysvinit -rw-r--r-- 1 root root 2 dic 14 2016 whoami root@deadpool:/var/lib/ceph/osd/ceph-6# ceph-osd -i 6 --mkjournal 2019-02-06 17:45:35.030359 7ff679c24880 -1 journal check: ondisk fsid 00000000-0000-0000-0000-000000000000 doesn't match expected 70357923-3227-4d57-980f-92b8c853dc76, invalid (someone else's?) journal 2019-02-06 17:45:35.038522 7ff679c24880 -1 created new journal /var/lib/ceph/osd/ceph-6/journal for object store /var/lib/ceph/osd/ceph-6 Clearly i've changed the journal partition by hand (eg, direct link) so i'm expecting that link is 'direct to partition'; but, and see the warning about fsid, still there's no 'id' associated to that partition (eg, no link in /dev/disk/by-*/). If i rerun the 'mkjournal': root@deadpool:/var/lib/ceph/osd/ceph-6# ceph-osd -i 6 --mkjournal 2019-02-06 17:45:37.621855 7f3391377880 -1 created new journal /var/lib/ceph/osd/ceph-6/journal for object store /var/lib/ceph/osd/ceph-6 So seems that effectively journal partition get 'tagged' in someway. But i'm still confused... using ID link in journal partitions works only for GPO partitioning? Thanks. -- dott.
