Subject: [ceph-users] cephfs issue with moving files between data pools
gives Input/output error
Looks like that if I move files between different data pools of the
cephfs, something is still refering to the 'old location' and gives an
Input/output error. I assume this, because I am using different client
ids for authentication.
With the same user as configured in ganesha, mounting (kernel) erasure
code cephfs m can create file out4
At nfs4 client, same location m
I can read out4
I can create out5
I can read out5
Mounted root cephfs create file in folder t (test replicated 1) I can
create out6 I can move out6 to a the folder m (erasure coded) I can read
out6
At nfs4 client, m location
[@m]# cat out6
cat: out6: Input/output error
