The issue was introduced by https://github.com/ceph/ceph/commit/0887ea42e2e5585580d4a8a387f24ad6dafb091e#diff-7b2752174570bb104c55d6bce2c9ab5b.

Also see https://github.com/ceph/ceph/pull/30943.

After adding some commands for debugging the issue i got this in Teuthology.

+ cd src/pybind/mgr/dashboard
+ timeout 7200 ./run-frontend-e2e-tests.sh
+ ls -alh /dev/tty
crw-rw-rw-. 1 root tty 5, 0 Oct 29 10:06 /dev/tty
+ '[' -e /dev/tty -a '!' -t 2 ']'
+ tee /dev/tty
+ echo '** going verbose **'
tee: /dev/tty: No such device or address
** going verbose **

+ cd src/pybind/mgr/dashboard
+ timeout 7200 ./run-frontend-e2e-tests.sh
+ ls -alh /dev/tty
+ ls -al /proc/self/fd/

I'm not familar with how Teuthology and Jenkis are working together, but i found some blog posts that let me think that Jenkins does not provide a /dev/tty console when running the run-frontend-e2e-tests.sh script (what is strange because the device file eixts, see post above). Now trying to use /dev/stderr instead as suggested in a blog post.

+ cd src/pybind/mgr/dashboard
+ timeout 7200 ./run-frontend-e2e-tests.sh
+ ls -alh /dev/stderr
lrwxrwxrwx. 1 root root 15 Oct 29 12:31 /dev/stderr -> /proc/self/fd/2
+ ls -al /proc/self/fd/
