Dear all,
I want to mirror a snapshot in Ceph v16.2.6 deployed with cephadm
using the stock quay.io images. My source file system has a folder
"/src/folder/x" where "/src/folder" has mode "ug=r,o=", in other words
no write permissions for the owner (root).
The sync of a snapshot "initial" now fails with the following log excerpt.
remote_mkdir: remote epath=./src/folder/x
remote_mkdir: failed to create remote directory=./src/folder/x: (13)
Permission denied
do_synchronize: closing local directory=./src/folder
do_synchronize: closing local directory=./src/
do_synchronize: closing local directory=.
post_sync_close_handles
do_sync_snaps: failed to synchronize dir_root=/src/folder, snapshot=initial
sync_snaps: failed to sync snapshots for dir_root=/src/folder
The capabilities on the remote site are:
client.mirror-tier-2-remote
key: REDACTED
caps: [mds] allow * fsname=cephfs
caps: [mon] allow r fsname=cephfs
caps: [osd] allow * tag cephfs data=cephfs
I also just reported this in the tracker [1]. Can anyone think of a
workaround (in the lines of "sudo make me a sandwich ;-)?"
Best wishes,
Manuel
