Hi!
We have a CephFS directory /baremetal mounted as /cephfs via FUSE on
our clients.
There are no specific settings configured for /baremetal.
As a result, trying to get the directory layout via getfattr does not work
getfattr -n 'ceph.dir.layout' /cephfs
/cephfs: ceph.dir.layout: No such attribute
Using a dummy file I can work around this to get at least at the pool name:
➜ touch dummy.txt
➜ getfattr -n 'ceph.file.layout' dummy.txt
# file: dummy.txt
ceph.file.layout="stripe_unit=4194304 stripe_count=1
object_size=4194304 pool=cephfs"
(BTW: Why doesn't getfattr -d -m - dummy.txt show any of the Ceph attributes?)
Now, say I wanted to put /baremetal into a different pool, how would I
go about this?
Can I setfattr on the /cephfs mountpoint and assign it a different pool
with e. g. different replication settings?
Or would I need to mount the CephFS / directory somewhere and modify
the settings for /baremetal from there?
Can I change this after the fact at all, or do I have to mount both
pools at the same time and move data between them manually?
Thanks a lot!
Daniel
