I will explain the test again, I think you might have some bug in your cephfs copy between data pools. c04 has mounted the root cephfs /a (has data pool a, ec21) /test (has data pool b, r1) test2 has mounted /m (nfs mount of cephfs /a) /m2 (cephfs mount of /a) Creating the test file. [root@c04 test]# echo asdfasdfasdfasdfasdfasdfasdfasdfasdf > testfile.txt Then I am moving on c04 the test file from the test folder(pool b) to the a folder/pool Now on test2 [root@test2 m]# ls -arlt -rw-r--r-- 1 nobody nobody 21 Oct 1 20:48 r1.txt -rw-r--r-- 1 nobody nobody 21 Oct 1 20:49 r1-copy.txt -rw-r--r-- 1 nobody nobody 37 Oct 1 21:02 testfile.txt [root@test2 /]# cat /mnt/m/testfile.txt cat: /mnt/m/old/testfile.txt: Input/output error [root@test2 /]# cat /mnt/m2/testfile.txt cat: /mnt/m2/old/testfile.txt: Operation not permitted Now I am creating a copy of the test file in the same directory back on c04 [root@c04 a]# cp testfile.txt testfile-copy.txt [root@c04 a]# ls -alrt -rw-r--r-- 1 root root 21 Oct 1 20:49 r1-copy.txt -rw-r--r-- 1 root root 37 Oct 1 21:02 testfile.txt -rw-r--r-- 1 root root 37 Oct 1 21:07 testfile-copy.txt Now I trying to access the copy of testfile.txt back on test2 (without unmounting, or changing permissions) [root@test2 /]# cat /mnt/m/testfile-copy.txt asdfasdfasdfasdfasdfasdfasdfasdfasdf [root@test2 /]# cat /mnt/m2/testfile-copy.txt asdfasdfasdfasdfasdfasdfasdfasdfasdf -----Original Message----- From: Yan, Zheng [mailto:ukernel@xxxxxxxxx] Sent: zaterdag 29 september 2018 6:55 To: Marc Roos Subject: Re: cephfs issue with moving files between data pools gives Input/output error check_pool_perm on pool 30 ns need Fr, but no read perm client does not permission to read the pool. ceph-fuse did return EPERM for the kernel readpage request.
