Bug #47236
Updated by Patrick Donnelly over 3 years ago
In an Ubuntu 20.04 environment with Ceph Nautilus (ceph version 14.2.11-99-gaf0268dc91 (af0268dc910f84b47655e83a83ca54b6fb92dbaf) nautilus (stable)) I get a "Cannot send after transport endpoint shutdown" when the access mode for a volume is changed. Steps to reproduce: - Create subvolume - Mount subvolume - Grant RW access to the subvolume - Write some data - Change RW access to RO access to the subvolume - Try to access the subvolume Expected output: - Access the subvolume and read written data. Try to write data and get a operation forbidden error Actual output: <pre> manila@ubuntu:~$ sudo ceph-fuse ~/mnt --id=vkmc --conf=ceph.conf --keyring=vkmc.keyring --client-mountpoint=/volumes/_nogroup/59c7a611-6c43-4633-b919-500cd043941f 2020-08-31T22:17:10.512+0000 7f8f21b52080 -1 init, newargv = 0x5605c2d7eb40 newargc=9 ceph-fuse[604]: starting ceph client ceph-fuse[604]: starting fuse manila@ubuntu:~$ cd mnt/ manila@ubuntu:~/mnt$ sudo touch x manila@ubuntu:~/mnt$ sudo touch y manila@ubuntu:~/mnt$ sudo touch z manila@ubuntu:~/mnt$ ls x y z manila@ubuntu:~/mnt$ sudo vim x manila@ubuntu:~/mnt$ sudo vim y manila@ubuntu:~/mnt$ sudo vim z manila@ubuntu:~/mnt$ cat x foo manila@ubuntu:~/mnt$ cat y bar manila@ubuntu:~/mnt$ cat z foobar manila@ubuntu:~/mnt$ cd .. manila@ubuntu:~$ ls ls: cannot access 'mnt': No such file or directory another-mnt ceph.conf mnt vkmc.keyring manila@ubuntu:~$ ls ls: cannot access 'mnt': No such file or directory another-mnt ceph.conf mnt vkmc.keyring manila@ubuntu:~$ cd mnt manila@ubuntu:~/mnt$ ls ls: cannot open directory '.': Cannot send after transport endpoint shutdown manila@ubuntu:~/mnt$ cd ,, -bash: cd: ,,: Cannot send after transport endpoint shutdown manila@ubuntu:~/mnt$ cd .. manila@ubuntu:~$ ls ls: cannot access 'mnt': No such file or directory another-mnt ceph.conf mnt vkmc.keyring manila@ubuntu:~$ ls -la ls: cannot access 'mnt': No such file or directory total 44 drwxr-xr-x 6 manila manila 4096 Aug 31 22:16 . drwxr-xr-x 3 root root 4096 Aug 17 17:47 .. -rw-r--r-- 1 manila manila 220 Feb 25 2020 .bash_logout -rw-r--r-- 1 manila manila 3771 Feb 25 2020 .bashrc drwx------ 2 manila manila 4096 Aug 31 22:06 .cache -rw-r--r-- 1 manila manila 807 Feb 25 2020 .profile drwx------ 2 manila manila 4096 Aug 31 22:05 .ssh -rw------- 1 manila manila 1614 Aug 31 22:16 .viminfo drwxrwxr-x 2 manila manila 4096 Aug 31 22:11 another-mnt -rw-rw-r-- 1 manila manila 76 Aug 31 22:16 ceph.conf d????????? ? ? ? ? ? mnt -rw-rw-r-- 1 manila manila 69 Aug 31 22:08 vkmc.keyring manila@ubuntu:~$ cat vkmc.keyring [client.vkmc] key = AQAwdE1f7FV/NRAAEBrHgLVr6a84D0mkm0qlcA== manila@ubuntu:~$ ls -la ls: cannot access 'mnt': No such file or directory total 44 drwxr-xr-x 6 manila manila 4096 Aug 31 22:28 . drwxr-xr-x 3 root root 4096 Aug 17 17:47 .. -rw-r--r-- 1 manila manila 220 Feb 25 2020 .bash_logout -rw-r--r-- 1 manila manila 3771 Feb 25 2020 .bashrc drwx------ 2 manila manila 4096 Aug 31 22:06 .cache -rw-r--r-- 1 manila manila 807 Feb 25 2020 .profile drwx------ 2 manila manila 4096 Aug 31 22:05 .ssh -rw------- 1 manila manila 2039 Aug 31 22:28 .viminfo drwxrwxr-x 2 manila manila 4096 Aug 31 22:11 another-mnt -rw-rw-r-- 1 manila manila 76 Aug 31 22:16 ceph.conf d????????? ? ? ? ? ? mnt -rw-rw-r-- 1 manila manila 69 Aug 31 22:28 vkmc.keyring manila@ubuntu:~$ cd mnt manila@ubuntu:~/mnt$ ls ls: cannot open directory '.': Cannot send after transport endpoint shutdown manila@ubuntu:~/mnt$ cd .. manila@ubuntu:~$ umount mnt umount: mnt: No such file or directory manila@ubuntu:~$ sudo ceph-fuse ~/mnt --id=vkmc --conf=ceph.conf --keyring=vkmc.keyring --client-mountpoint=/volumes/_nogroup/59c7a611-6c43-4633-b919-500cd043941f 2020-08-31T22:28:31.932+0000 7fb3789fc080 -1 init, newargv = 0x55ec8baeb7a0 newargc=9 fuse: bad mount point `/home/manila/mnt': No such file or directory 2020-08-31T22:28:31.936+0000 7fb3789fc080 -1 fuse_parse_cmdline failed. ceph-fuse[690]: fuse failed to initialize </pre>
