Hello,
I have suddenly let 2 OSDs in our small 2 node cluster to be filled.
Reading from the docs, i move 2 pgs dirs to another disk, so that free some disk space.
Unfortunately after this the osd cannot start.
Please advice! This happened before the 2:2 replication end, so it is absolutely needed to get the data back.
Thank you very much!
Here's the log from the osd from which i moved directories:
