Hi
We're having problems getting our erasure coded ec82pool to upmap balance.
"ceph version 14.2.11 (f7fdb2f52131f54b891a2ec99d8205561242cdaf)
nautilus (stable)": 554
The pool consists of 20 nodes in 10 racks, each rack containing a pair
of nodes 1@45*8TB drives and 1@10*16TB.
https://pastebin.com/YLwu8VVi
The problem is the 8TB drives are roughly 62-74% full, while the 16TB
drives are 84-87% full.
https://pastebin.com/j7Dx883i
Neither osdmaptool or reweight-by-utilization are able to improve the
distribution .
There's an osdmap ftp://ftp.mrc-lmb.cam.ac.uk/pub/toby/osdmap.2135441.
Any thoughts/pointers much appreciated.
Cheers
Toby
