Re: [ceph-users] client with uid
Hi Patrick, Thanks for the info. Looking at the fuse options in the man page, I should be able to pass "-o uid=$(id -u)" at the end of the ceph-fuse command. However, when I do, it returns with an unknown option for fuse and segfaults. Any pointers would be greatly appreciated. This is the result I get: daemoneye@wolterk:~$ ceph-fuse --id=kwolter_test1 -r /user/kwolter/ /home/daemoneye/ceph/ --client-die-on-failed-remount=false -o uid=$(id -u) ceph-fuse[25156]: starting ceph client fuse: unknown option `uid=1000' ceph-fuse[25156]: fuse failed to start *** Caught signal (Segmentation fault) ** in thread 7efc7da86100 thread_name:ceph-fuse ceph version 12.2.2 (cf0baba3b47f9427c6c97e2144b094b7e5ba) luminous (stable) 1: (()+0x6a8784) [0x5583372d8784] 2: (()+0x12180) [0x7efc7bb4f180] 3: (Client::_ll_drop_pins()+0x67) [0x558336e5dea7] 4: (Client::unmount()+0x943) [0x558336e67323] 5: (main()+0x7ed) [0x558336e02b0d] 6: (__libc_start_main()+0xea) [0x7efc7a892f2a] 7: (_start()+0x2a) [0x558336e0b73a] ceph-fuse [25154]: (33) Numerical argument out of domain daemoneye@wolterk:~$ Thanks, Keane On Thu, Jan 25, 2018 at 5:50 PM, Patrick Donnelly wrote: > On Wed, Jan 24, 2018 at 7:47 AM, Keane Wolter wrote: > > Hello all, > > > > I was looking at the Client Config Reference page > > (http://docs.ceph.com/docs/master/cephfs/client-config-ref/) and there > was > > mention of a flag --client_with_uid.

The uid/gid should be provided by FUSE so you don't need to do anything. If you're using the client library, you provide the uid/gid via the UserPerm struct to each operation.

[ceph-users] client with uid
Hello all, I was looking at the Client Config Reference page ( http://docs.ceph.com/docs/master/cephfs/client-config-ref/) and there was mention of a flag --client_with_uid. The way I read it is that you can specify the UID of a user on a cephfs and the user mounting the filesystem will act as the same UID. I am using the flags --client_mount_uid and --client_mount_gid set equal to my UID and GID values on the cephfs when running ceph-fuse. Is this the correct action for the flags or am I misunderstanding the flags? Thanks, Keane ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
