Hi all,
I'm playing with my testing cluster with ceph 12.2.8 installed.
It happened to me for the second time, that I have 1 unfound objects on erasure coded pool.
I have erasure with 3+1 configuration.
First time I was adding additional disk. During cluster rebalance I noticed one unfound object. I hoped, that it will be fixed after cluster
rebalance, but it was not.
I coped with marking object as lost, because disk IO on that object stuck.
Yesterday I was trying to remove one disk so I marked it out.
After few hours I noticed also one object unfound. This is dump of pg list_missing.
There is strange pool number, snapid (I'm not using snapshots on that pool, it is just pool for cephfs data), also locations array looks
strange.
I decided to put disk I wanted to remove back "in" and unfound object disappeared.
Can you give me additional informations to this problem? Should I debug it more?
Thank you
