Backgroup: my pod run user is app, but my cephfs-csi created pvc storage is root so ,I hope the running identity I created is a normal user app, not root, how to solve it

Can you try with --setuser=appops and try again?

[lu-you]

--setuser=appops

yes

And my host ceph-fuse version v14, cephcsi container ceph-fuse version is v18

[lu-you]

Can you try with --setuser=appops and try again?

And k8s version is 1.21，cephfs-csi is latest

[lu-you]

Can you try with --setuser=appops and try again?

is it because of the reason of ',' ?

-o nonempty --setuser appops --setgroup appops

So , I strongly suspect that the problem is caused by ","

[nixpanic]

maybe try without spaces and leading --, like setuser=appops,setgroup=appops.

No, I tried

you can have a look code， https://github.com/ceph/ceph-csi/blob/devel/internal/util/util.go#L357 or https://github.com/ceph/ceph-csi/blob/3410687855f8fa10a4addfb337e2d2512634a980/internal/cephfs/mounter/fuse.go#L50

[lu-you]

maybe try without spaces and leading --, like setuser=appops,setgroup=appops.

And i think it's still a problem ---> ","

[nixpanic]

The -o option can take a single string with options separated by ,, so -o setuser=appops,setgroup=appops should be valid.

look at it is , I tried, really can't

[nixpanic]

that is unfortunate, it seems the -o option does not accept the setuser parameter :disappointed:

I do not see a setuser option in the cephfs-fuse manual, are you certain that the option is supported?

[lu-you]

that is unfortunate, it seems the -o option does not accept the setuser parameter 😞

I do not see a setuser option in the cephfs-fuse manual, are you certain that the option is supported?

ceph-fuse -h usage: ceph-fuse [-n client.username] [-m mon-ip-addr:mon-port] [OPTIONS] --client_mountpoint/-r <sub_directory> use sub_directory as the mounted root, rather than the full Ceph tree.

usage: ceph-fuse mountpoint [options]

general options: -o opt,[opt...] mount options -h --help print help -V --version print version

FUSE options: -d -o debug enable debug output (implies -f) -f foreground operation -s disable multi-threaded operation

--conf/-c FILE read configuration from the given configuration file --id ID set ID portion of my name --name/-n TYPE.ID set name --cluster NAME set cluster name (default: ceph) --setuser USER set uid to user or uid (and gid to user's gid) --setgroup GROUP set gid to group or gid --version show version and quit

Aha，I checked the ceph-use -h

Can this parameter be supported?
