Hi All,
Recently our ceph storage is running at low performance. Today, we can not write to the folder. We tried to unmount the ceph storage then to re-mount it, however, we can not even mount it now:
# mount -v -t ceph igc-head,is1,i1,i2,i3:6789:/ /mnt/igcfs/ -o name=admin,secretfile=/etc/admin.secret
parsing options: rw,name=admin,secretfile=/etc/admin.secret
mount error 5 = Input/output error
Previously there are some nearly full osd, so we did the "ceph osd reweight-by-utilization" to rebalance the usage. The ceph health is not ideal but it should still alive. Please help me to mount the disk again.
