Hi All,
Having a few problems removing cephfs file systems.
I want to remove my current pools (was used for test data) - wiping all current
data, and start a fresh file system on my current cluster.
I have looked over the documentation but I can't find anything on this. I have
an object store pool, Which I don't want to remove - but I'd like to remove the
cephfs file system pools and remake them.
My cephfs is called 'data'.
Running ceph fs delete data returns: Error EINVAL: all MDS daemons must be
inactive before removing filesystem
To make an MDS inactive I believe the command is: ceph mds deactivate 0
Which returns: telling mds.0 135.248.53.134:6809/16692 to deactivate
Checking the status of the mds using: ceph mds stat returns: e105: 1/1/0 up
{0=node2=up:stopping}
This has been sitting at this status for the whole weekend with no change. I
don't have any clients connected currently.
When trying to manually just remove the pools, it's not allowed as there is a
cephfs file system on them.
I'm happy that all of the failsafe's to stop someone removing a pool are all
working correctly.
If this is currently undoable. Is there a way to quickly wipe a cephfs
filesystem - using RM from a kernel client is really slow.
Many thanks
Warren Jeffs
