Hi Loic, Yes I upgraded the cluster, it is definately not new. I ran into several other issues as well, for instance legacy tunables that had to be changed.
These are the directory contents you asked for: # ls -al /usr/lib64/ceph/erasure-code totaal 776 drwxr-xr-x. 2 root root 4096 12 jun 21:36 . drwxr-xr-x. 3 root root 4096 12 jun 21:36 .. lrwxrwxrwx. 1 root root 22 12 jun 21:36 libec_example.so -> libec_example.so.0.0.0 lrwxrwxrwx. 1 root root 22 12 jun 21:36 libec_example.so.0 -> libec_example.so.0.0.0 -rwxr-xr-x. 1 root root 381240 14 mei 17:44 libec_example.so.0.0.0 lrwxrwxrwx. 1 root root 33 12 jun 21:36 libec_fail_to_initialize.so -> libec_fail_to_initialize.so.0.0.0 lrwxrwxrwx. 1 root root 33 12 jun 21:36 libec_fail_to_initialize.so.0 -> libec_fail_to_initialize.so.0.0.0 -rwxr-xr-x. 1 root root 6032 14 mei 17:44 libec_fail_to_initialize.so.0.0.0 lrwxrwxrwx. 1 root root 31 12 jun 21:36 libec_fail_to_register.so -> libec_fail_to_register.so.0.0.0 lrwxrwxrwx. 1 root root 31 12 jun 21:36 libec_fail_to_register.so.0 -> libec_fail_to_register.so.0.0.0 -rwxr-xr-x. 1 root root 6032 14 mei 17:44 libec_fail_to_register.so.0.0.0 lrwxrwxrwx. 1 root root 20 12 jun 21:36 libec_hangs.so -> libec_hangs.so.0.0.0 lrwxrwxrwx. 1 root root 20 12 jun 21:36 libec_hangs.so.0 -> libec_hangs.so.0.0.0 -rwxr-xr-x. 1 root root 6024 14 mei 17:44 libec_hangs.so.0.0.0 lrwxrwxrwx. 1 root root 23 12 jun 21:36 libec_jerasure.so -> libec_jerasure.so.2.0.0 lrwxrwxrwx. 1 root root 23 12 jun 21:36 libec_jerasure.so.2 -> libec_jerasure.so.2.0.0 -rwxr-xr-x. 1 root root 364696 14 mei 17:44 libec_jerasure.so.2.0.0 lrwxrwxrwx. 1 root root 34 12 jun 21:36 libec_missing_entry_point.so -> libec_missing_entry_point.so.0.0.0 lrwxrwxrwx. 1 root root 34 12 jun 21:36 libec_missing_entry_point.so.0 -> libec_missing_entry_point.so.0.0.0 -rwxr-xr-x. 1 root root 5944 14 mei 17:44 libec_missing_entry_point.so.0.0.0 Kind regards, Erik.
