Hey,
I'm trying to find the last two objects on an old data pool for a cephfs
cluster that seemingly aren't found via find && getfattr.
More generically though, is there a low level tool or (C++ or Python)
library for reading and analyzing cephfs metadata?

Is the balancer activated? (upmap?)

Hey,
I'm running ceph version 18.2.1 (reef) but this problem must have existed a
long time before reef.
The documentation says the autoscaler will target 100 pgs per OSD but I'm
only seeing ~10. My erasure encoding is a stripe of 6 data 3 parity.
Could that be the reason? PGs numbers for that EC

I recently moved to quincy and cephadm.
I noticed that when I moved some drives from one machine to another they at
some point got marked as weight 0 in the crushmap.
The first time that was fine, I just fixed it and figured it was something
I did wrong with moving the drives.
The second time it
Do you think maybe you should issue an immediate change/patch/update to
quincy to change the default to wpq? Given the cluster ending nature of the
problem?

median CPU usage of some multiple of 100% (eg. a multiple of a machine
core/thread usage per osd).

Also never had problems with backfill / rebalance / recovery but now seen
runaway CPU usage even with very conservative recovery settings after
upgrading to quincy from pacific.
osd_recovery_sleep_hdd = 0.1
osd_max_backfills = 1
osd_recovery_max_active = 1
osd_recovery_delay_start = 600

Does a stripe aware file copier exist for cephfs to parallelize the copying
of one larger file?
