Hello
I have a ceph cluster of 6 osd 146gb each. I have copied a lot of data
filling to 87%. Between the osd's the data is not evenly distributed
host1
/dev/sdb 137G 119G 15G 90% /data/osd0
/dev/sdc 137G 126G 7.4G 95% /data/osd1
host2
/dev/sdc 137G 114G 21G 85% /data/osd2
/dev/sdd 137G 130G 3.6G 98% /data/osd3
host3
/dev/sdb 137G 107G 27G 81% /data/osd4
/dev/sdc 137G 98G 36G 74% /data/osd5
During the copy i got I/O error, but after restarting the cluster it seems fine.
By some reason osd3 seems to have much more data than osd5. Is there a way of geting the data distributed better ?.
