mds container dies during deployment - ceph-users

25 May 2020

Hello everyone

I've got a fresh ceph octopus installation and I'm trying to set up a cephfs with
erasure code configuration.
The metadata pool was set up as default.
The erasure code pool was set up with this command:
-> ceph osd pool create ec-data_fs 128 erasure default
Enabled overwrites:
-> ceph osd pool set ec-data_fs allow_ec_overwrites true
And create fs:
-> ceph fs new ec-data_fs meta_fs ec-data_fs --force

Then I tried deploying the mds, but this fails:
-> ceph orch daemon add mds ec-data_fs magma01
returns:
-> Deployed mds.ec-data_fs.magma01.ujpcly on host 'magma01'

The mds daemon is not there.

Aparently the container dies without any information, as seen in the journal:

Can someone help me debugging this?
