Description

I have a pacific cluster with 129 osds.
When I use the rbd map command it fails with :

rbd: sysfs write failed
In some cases useful info is found in syslog - try "dmesg | tail".
rbd: map failed: (110) Connection timed out.

When I check the dmesg this is what it reports:

[3744063.722353] libceph: mon0 .*..*:6789 io error
[3744063.722414] libceph: mon0 .*..*:6789 session lost, hunting for new mon
[3744063.723915] libceph: mon2 .*..*:6789 session established

[3744063.785524] libceph: mon1 .*..*:6789 session established
[3744063.842524] libceph: mon1 .*..*:6789 io error

I have tried everything possible but to no avail. Also do not know if rbd_config_pool_override_update_timestamp 1652886042
in my config setting is causing a problem.
