Some time ago on Luminous I also had to change the crush rules on a all hdd cluster to hdd (to prepare for adding ssd's and ssd pools). And pg's started migrating while everything already was on hdd's, looks like this is still not fixed? -----Original Message----- From: Raymond Berg Hansen [mailto:raymondbh@xxxxxxxxx] Sent: dinsdag 1 oktober 2019 14:32 To: ceph-users@xxxxxxx Subject: Re: Nautilus pg autoscale, data lost? You are absolutly right, I had made a crush rule for device class hdd. Did not put this in connection with this problem. When I put the pools back in the default crush rule things are starting to fix itself it seems. Have I done something wrong with this crush rule? # rules rule replicated_rule { id 0 type replicated min_size 1 max_size 10 step take default step chooseleaf firstn 0 type host step emit } rule replicated-hdd { id 1 type replicated min_size 1 max_size 10 step take default class hdd step chooseleaf firstn 0 type datacenter step emit } _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
