Hello,
we have set up a snap-mirror for a directory on one of our clusters -
running ceph version
ceph version 16.2.7 (dd0603118f56ab514f133c8d2e3adfc983942503) pacific
(stable)
to get mirrorred our other cluster - running ceph version
ceph version 16.2.9 (4c3647a322c0ff5a1dd2344e039859dcbd28c830) pacific
(stable)
The initial setup went ok, when the first snapshot was created data
started to flow at a decent (for our HW) rate of 100-200MB/s. As the
directory contains ~200TB this was expected to take some time - but now
the process has stalled completely after ~100TB were mirrored and ~7d
running.
Up to now I do not have any hints why it has stopped - I do not see any
error messages from the cephfs-mirror daemon. Can the small version
mismatch be a problem?
Any hints where to look to find out what has got stuck are welcome.
Regards,
Holger
